Board LayoutSince spread spectrum affects the m counter values, all spread-spectrumPLL outputs are effected. Therefore, if only one spread-spectrum signal isneeded, the clock signal should use a separate PLL without other outputsfrom that PLL.No special considerations are needed when using spread spectrum withthe clock switchover feature. This is because the clock switchover featuredoes not affect the m and n counter values, which are the counter valuesswitching when using spread spectrum.Board Layout The enhanced and fast PLL circuits in Stratix II and Stratix II GX devicescontain analog components embedded in a digital device. These analogcomponents have separate power and ground pins to minimize noisegenerated by the digital components. Stratix II and Stratix II GXenhanced and fast PLLs use separate V CC and ground pins to isolatecircuitry and improve noise resistance.V CCA and GNDAEach enhanced and fast PLL uses separate V CC and ground pin pairs fortheir analog circuitry. The analog circuit power and ground pin for eachPLL is called VCCA_PLL<PLL number> and GNDA_PLL<PLL number>.Connect the V CCA power pin to a 1.2-V power supply, even if you do notuse the PLL. Isolate the power connected to V CCA from the power to therest of the Stratix II or Stratix II GX device or any other digital device onthe board. You can use one of three different methods of isolating theV CCA pin: separate V CCA power planes, a partitioned V CCA island withinthe V CCINT plane, and thick V CCA traces.Separate V CCA Power PlaneA mixed signal system is already partitioned into analog and digitalsections, each with its own power planes on the board. To isolate the V CCApin using a separate V CCA power plane, connect the V CCA pin to theanalog 1.2-V power plane.Partitioned V CCA Island Within V CCINT PlaneFully digital systems do not have a separate analog power plane on theboard. Since it is expensive to add new planes to the board, you can createislands for VCCA_PLL. Figure1–35 shows an example board layout withan analog power island. The dielectric boundary that creates the islandshould be 25 mils thick. Figure1–36 shows a partitioned plane withinV CCINT for V CCA.Advanced Featuresthe primary to the secondary clock for PLL reference. The design sendsout the clk0_bad, clk1_bad, and the clk_loss signals from the PLLto implement a custom switchover circuit.Figure1–17.Automatic Clock Switchover Circuit Block DiagramThere are two possible ways to use the clock switchover feature.■Use the switchover circuitry for switching from a primary tosecondary input of the same frequency. For example, in applicationsthat require a redundant clock with the same frequency as theprimary clock, the switchover state machine generates a signal thatcontrols the multiplexer select input shown on the bottom ofFigure1–17. In this case, the secondary clock becomes the referenceclock for the PLL. This automatic switchover feature only works forswitching from the primary to secondary clock.■Use the CLKSWITCH input for user- or system-controlled switchconditions. This is possible for same-frequency switchover or toswitch between inputs of different frequencies. For example, ifinclk0 is 66 MHz and inclk1 is 100 MHz, you must control theswitchover because the automatic clock-sense circuitry cannotmonitor primary and secondary clock frequencies with a frequencydifference of more than 20%. This feature is useful when clocksources can originate from multiple cards on the backplane,requiring a system-controlled switchover between frequencies ofoperation. You should choose the secondary clock frequency so thePLLs in Stratix II and Stratix II GX DevicesTable1–11 shows the physical pins and their purpose for the fast PLLs.For inclk port connections to pins, see “Clocking” on page1–62.Table1–11.Fast PLL Pins(Part 1 of2)Note(1)Pin DescriptionCLK0p/n Single-ended or differential pins that can drive the inclk port for PLLs 1, 2, 7 or 8.CLK1p/n Single-ended or differential pins that can drive the inclk port for PLLs 1, 2, 7 or 8.CLK2p/n Single-ended or differential pins that can drive the inclk port for PLLs 1, 2, 7 or 8.CLK3p/n Single-ended or differential pins that can drive the inclk port for PLLs 1, 2, 7 or 8.

The charge current is programmable to USB100, USB500 or ISET mode and the CV mode voltage is fixed at 4.2V. The pre-charge threshold is fixed at 2.5V. If the battery voltage is below the pre-charge threshold, the RT9524 charges the battery with a trickle current until the battery voltage rises above the pre-charge threshold. The RT9524 is capable of being powered up from AC adapter and USB (Universal Serial Bus) port inputs. Moreover, the RT9524 include a linear regulator (LDO 4.9V, 50mA) for supplying low power external circuitry.ACIN Over Voltage ProtectionThe input voltage is monitored by the internal comparator and the input over voltage protection threshold is set to 6.9V. However, input voltage over 28V will still cause damage to the RT9524. When the input voltage exceeds the threshold, the comparator outputs a logic signal to turn off the power P-MOSFET to prevent the high input voltage from damaging the electronics in the handheld system. When the input over voltage condition is removed, the comparator re-enables the output by running through the soft-start.Charger Enable and mode SettingEN/SET is used to enable or disable the charger as well as to select the charge current limit. Drive the EN pin to low or leave it floating to enable the charger. The EN/SET pin has a 200kΩ internal pull down resistor. So, when left floating, the input is equivalent to logic low. Drive this pin to high to disable the charger. After the EN/SET pin pulls low for 50μs, the RT9524 enters the USB500 mode and wait for the setting current signal. EN/SET can be used to program the charge current during this cycle. The RT9524 will change its charge current by sending different pulse to EN/SET pin. If no signal is sent to EN/SET, the RT9524 will remain in USB500 mode. A correct period of time for high pulse is between 100μs and 700μs and the period of pulse to pulse must be between 100μs and 700μs to be properly read. Once EN/SET is held low for 1.5ms,the number of pulses is locked and sent to the control logic and then the mode changes. The RT9524 needs to be restarted to reset the charge current. Once the EN/ SET input is held high for more than 1.5ms, the RT9524 is disabled.Table 1. Pulse Counting Map for EN/SET InterfaceFigure .1 (b)Battery Charge ProfileThe RT9524 charges a Li-Ion battery with a constant current (CC) or a constant voltage (CV).The constant current is decided by the operation mode of USB100, USB500 or ISET mode. The constant current is set with the external resistor R ISET and the constant voltage is fixed at 4.2V. If the battery voltage is below the Pre-Charge Threshold, the RT9524 charges the battery with a trickle current until the battery voltage rises above the trickle charge threshold. When the battery voltage reaches 4.2V, the charger enters CV mode and regulates the battery voltage at 4.2V to fully charge the battery without the risk of over chargingFigure .1 (a)IIDS9524-01 April 2011Battery Pre-Charge CurrentDuring a charge cycle, if the battery voltage is below the pre-charge threshold, the RT9524 enters the pre-charge mode. This feature revives deeply discharged cells and protects battery. Under USB100 Mode, the pre-charge current is internally set to 95mA. When the RT9524 is under USB500 and ISET Mode, the pre-charge current is 20% of fast-charge current set by external resistor R ISET .Battery Fast-Charge Current ISET ModeThe RT9524 offers ISET pin to program the charge current.The resistor R ISET is connected to ISET and GND. The parameter K ISET is specified in the specification table.ISEF Charge ISEF ISETKI = ; K = 530R USB500 and USB100 ModeThe fast-charge current is 95mA in USB100 mode and 395mA in USB500 mode. Note that if the fast-charge current set by external resistor is smaller than that in USB500 mode (395mA), the RT9524 charges the battery in ISET mode.Battery Voltage Regulation (CV Mode)The battery voltage regulation feedback is through the BATT pin. The RT9524 monitors the battery voltage between BATT and GND pins. When the battery voltage closes in on the battery regulation voltage threshold, the voltage regulation phase begins and the charging current begins to taper down. When the charging current falls below the programmed end-of-charge current threshold,the CHGSB pin goes high to indicate the termination of charge cycle.The end-of-charge current threshold is set by the IEOC pin. The resistor R EOC is connected to IEOC and GND.The parameters K EOC and IEOC are specified in the specification table.EOC EOC EOC EOC RI (%) = ; K = 200K The current threshold of IEOC (%) is defined as the percentage of fast-charge current set by R ISET . After the CHGSB pin is pulled high, the RT9524 still monitors the battery voltage. Charge current is resumed when the battery voltage goes to lower than the battery regulation voltage threshold.Factory ModeThe RT9524 provides factory mode for supplies up to 2.3A for powering external loads with no battery installed and BATT is regulated to 4.2V. The factory mode allows the user to supply system power with no battery connected.In factory mode, thermal regulation is disabled but thermal protection (155°C) is still active. When using currents greater than 1.5A in factory mode, the user must limit the duty cycle at the maximum current to 20% with a maximum period of 10ms.LDOThe RT9524 integrates one low dropout linear regulator(LDO) that supplies up to 50mA. The LDO is active whenever the input voltage is between POR threshold andFigure 2Figure 32004006008001000120014000.40.60.81 1.2 1.4 1.61.82 2.22.4 2.62.83R SET ∠)B a t t e r yC h a r g e C u r r e n t (m A )(k ΩOVP threshold. It is not affected by the EN/SET input.Note that the LDO current is independence and not monitored by the charge current limit.Charge Status Outputs (CHGSB and PGB)The open-drain CHGSB and PGB outputs indicate various charger operations as shown in the following table. These status pins can be used to drive LEDs or communicate to the host processor. Note that ON indicates the open-drain transistor is turned on and LED is bright.Table 2Sleep ModeThe RT9524 enters sleep mode if the power is removed from the input. This feature prevents draining the battery during the absence of input supply.Temperature Regulation and Thermal Protection In order to maximize charge rate, the RT9524 features a junction temperature regulation loop. If the power dissipation of the IC results in a junction temperature greater than the thermal regulation threshold (125°C), the RT9524 limits the charge current in order to maintain a junction temperature around the thermal regulation threshold (125°C). The RT9524 monitors the junctiontemperature, T J , of the die and disconnects the battery from the input if T J exceeds 125°C. This operation continues until junction temperature falls below thermal regulation threshold (125°C) by the hysteresis level. This feature prevents maximum power dissipation from exceeding typical design conditions.Selecting the Input and Output CapacitorsIn most applications, all that is needed is a high-frequency decoupling capacitor on the input. A 1μF ceramic capacitor,placed in close proximity to input to GND, works well. Insome applications depending on the power supplycharacteristics and cable length, it may be necessary toadd an additional 10μF ceramic capacitor to the input.The RT9524 requires a small output capacitor for loop stability. A typical 1μF ceramic capacitor placed between the BATT pin and GND is sufficient.Thermal ConsiderationsFor continuous operation, do not exceed absolutemaximum operation junction temperature. The maximum power dissipation depends on thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. Themaximum power dissipation can be calculated by thefollowing formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum operation junctiontemperature, T A is the ambient temperature, and θJA is thejunction to ambient thermal resistance.For recommended operating conditions specification of RT9524, the maximum junction temperature is 125°C and T A is the maximum ambient temperature. The junction to ambient thermal resistance, θJA , is layout dependent. For WDFN-10L 3x2 packages, the thermal resistance, θJA , is 90°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formula :P D(MAX) = (125°C − 25°C) / (90°C/W) = 1.111W for WDFN-10L 3x2 packageThe maximum power dissipation depends on operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . For RT9524 package, the derating curveRT952411DS9524-01 April 2011in Figure 4 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 4. Derating Curve for RT9524 Package Layout ConsiderationThe RT9524 is a fully integrated low cost single-cell Li-Ion battery charger IC ideal for portable applications. Careful PCB layout is necessary. For best performance, place all peripheral components as close to the IC as possible. A short connection is highly recommended. The following guidelines should be strictly followed when designing a PCB layout for the RT9524.`Input capacitor should be placed close to the IC and connected to ground plane. The trace of input in the PCB should be placed far away from the sensitive devices or shielded by the ground.`The GND should be connected to a strong ground plane for heat sinking and noise protection.`The connection of R ISET and R IEOC should be isolated from other noisy traces. The short wire is recommended to prevent EMI and noise coupling.`Output capacitor should be placed close to the IC and connected to ground plane to reduce noise coupling.Figure 5.

Chapter 3:Memory Blocks in Arria II DevicesMemory Modes Figure3–18 shows the memory block in shift-register mode.Figure3–18.Shift-Register Memory ConfigurationROM ModeAll Arria II memory blocks support ROM mode. A .mif initializes the ROM contentsof these blocks. The address lines of the ROM are registered on M9K and M144Kblocks; however, they can be unregistered on MLABs. The outputs can be registeredor unregistered. Output registers can be asynchronously cleared. The ROM readoperation is identical to the read operation in the single-port RAM configuration.FIFO ModeAll memory blocks support FIFO mode. MLABs are ideal for designs with manysmall, shallow FIFO buffers. To implement FIFO buffers in your design, you can usethe FIFO MegaWizard Plug-In Manager in the Quartus II software. Both single- anddual-clock (asynchronous) FIFOs are supported.f For more information about implementing FIFO buffers, refer to the SCFIFO andDCFIFO Megafunctions User Guide.1MLABs do not support mixed-width FIFO mode.Arria II Device Handbook Volume 1: Device Interfaces and IntegrationChapter 9:Configuration, Design Security, and Remote System Upgrades in Arria II DevicesJTAG ConfigurationYou must connect the nCE pin to GND or drive it low during JTAG configuration. Inmulti-device FPP, AS, and PS configuration chains, the nCE pin of the first device isconnected to GND, while its nCEO pin is connected to nCE of the next device in thechain. The nCE input of the last device comes from the previous device, while its nCEOpin is left floating. In addition, the CONF_DONE and nSTATUS signals are all shared inmulti-device FPP, AS, or PS configuration chains so the devices can enter user mode atthe same time after configuration is complete. When the CONF_DONE and nSTATUSsignals are shared among all the devices, you must configure every device when JTAGconfiguration is performed.1If you only use JTAG configuration, Altera recommends connecting the circuitry as shown in Figure9–17, where each of the CONF_DONE and nSTATUS signals are isolated toenable each device to enter user mode individually.After the first device completes configuration in a multi-device configuration chain,its nCEO pin drives low to activate the nCE pin of the second device, which prompts thesecond device to begin configuration. Therefore, if these devices are also in a JTAGchain, ensure the nCE pins are connected to GND during JTAG configuration or thatthe devices are JTAG configured in the same order as the configuration chain. As longas the devices are JTAG configured in the same order as the multi-deviceconfiguration chain, the nCEO of the previous device drives the nCE of the next devicelow when it has successfully been JTAG configured.You can place other Altera devices that have JTAG support in the same JTAG chain fordevice programming and configuration.1JTAG configuration support is enhanced and allows more than 17 Arria II devices to be cascaded in a JTAG chain.f For more information about configuring multiple Altera devices in the sameconfiguration chain, refer to the Configuring Mixed Altera Device Chains chapter involume2 of the Configuration Handbook.You can configure Arria II devices using multiple configuration schemes on the sameboard. Combining JTAG configuration with a PS or AS configuration on your board isuseful in the prototyping environment because it allows multiple methods toconfigure your FPGA.f For more information about combining JTAG configuration with other configurationschemes, refer to the Combining Different Configuration Schemes chapter in volume2 ofthe Configuration Handbook.Arria II Device Handbook Volume 1: Device Interfaces and IntegrationChapter 3:Memory Blocks in Arria II DevicesDesign ConsiderationsPower-Up Conditions and Memory InitializationM9K and M144K block outputs power up to zero (cleared), regardless of whether theoutput registers are used or bypassed. MLABs power up to zero if the output registersare used and power up reading the memory contents if the output registers are notused. You must take this into consideration when designing logic that might evaluatethe initial power-up values of the MLAB memory block. For Arria II devices, theQuartus II software initializes the RAM cells to zero unless there is a .mif filespecified.All memory blocks support initialization using a .mif. You can create .mif files in theQuartus II software and specify their use with the RAM MegaWizard Plug-InManager when instantiating a memory in your design. Even if a memory ispre-initialized (for example, using a .mif), it still powers up with its outputs cleared.f For more information about .mif files, refer to the Internal Memory (RAM and ROM)Megafunction User Guide and the Quartus II Handbook.Power ManagementArria II memory block clock enables allow you to control clocking of each memoryblock to reduce AC-power consumption. Use the read-enable signal to ensure thatread operations only occur when you need them to. If your design does not requireread-during-write, you can reduce your power consumption by deasserting theread-enable signal during write operations or any period when no memoryoperations occur.The Quartus II software automatically places any unused memory block in low powermode to reduce static power.Arria II Device Handbook Volume 1: Device Interfaces and Integration。

automatically adjusts to the value required by the input frequency and resolution. This value ranges from zero to a maximum depen-dent on the oscillator frequency that is set via register FCTR.Serial Data OutputFor BiSS or SSI output the maximum possible con-verter frequency can be adjusted to suit the maxi-mum input frequency;an automatic converter resolu-tion step-down feature can be enabled via the FCTR register.Should the input frequency exceed the fre-quency limit of the selected converter resolution,the LSB is kept stable and not resolved any further;the interpolation resolution halves.If the next frequency limit is overshot,the LSB and LSB +1are kept stable and so on.If the input frequency again sinks below this frequency threshold,fine reso-lution automatically returns.With the programming of CRC6=1a resolution step-down will be signalled via the BiSS warning bit.Table14:Maximum converter frequency for serial data output.Rev D3,Page14/30Incremental Output to A,B and ZSettings for the maximum possible converter fre-quency using register FCTR are governed by two cri-teria:1.The maximum input frequency2.System restrictions caused by slow counters or data transmission via cableIn this case it is sensible to preselect a minimum tran-sition distance for the output signals.These settings also make a suitable zero-delay digital glitchfilter that acts on ESD impact on the sensor and keeps the out-put signals spike free through temporal separation,for example.Serial data output is possible at any time in BiSS or SSI protocol.However,for the transfer of angle data to the output register the incremental output is halted for one period of the clock signal at pin MA.Table15:Maximum possible converter frequency for incremental A/B/Z output, defined by the maximum input frequencyTable16:Maximum possible converter frequency for incremental A/B/Z

key on the left.T wo error bits are provided to enable communication via the I/O interface;these bits can decode four differ-ent types of error.If NERR is held at low by an external source,such as an error message from the system,for example,this can also be verified via the I/O interface.Error are stored until the sensor data is output via the I/O interface and then deleted.Errors at NERR are displayed for a minimum of ca.10ms unless they are deleted beforehand by a data output.Rev D3,Page 18/30If an error in amplitude occurs,conversion is termi-nated and the incremental output signals halted.Anerror in amplitude rules out the possibility of an errorin frequency.Table 30:T est modeT able 31:Analog test modeSDA: Sin+A: COS+5 VX/Y 0 V1 V/Div vert. 1 V/Div hor.Y/T 1 V/Div vert.Figure

adjust-ments;X/Y mode is preferable for PHASE.T est signals COS-(pin B)and SIN-(pin SCL)must be selected to set negative values for OFFS.Rev D3,Page19/30The serial I/O interface operates in BiSS C protocol mode and enables sensor data to be output in uninter-ruptible cycles(data channel SCD).At the same time parameters can be exchanged via bidirectional register communication(data channel CD).The sensor data produced by iC-NQC contains the an-gle value(S)with3to13bits,the period count(P)with 0,8,12or24bits,two error bits(E1and E0)and5or 6CRC bits(CRC).Figure16:Example line signals(BiSS

number of period counter bits sent as sensor data.The counter bits are trans-mitted before the angle value,with the MSB leading.The5-bit CRC output is based on polynomial0x25 (100101b),with the6-bit CRC output based on poly-nomial0x43(1000011b)automatically coming active with longer SCD data,or when preselected by CRC6. As a rule,CRC bits are sent inverted.An additional zero bit can be output following the CRC bits.However,disabling the zero bit by NZB=1is rec-ommended when the output data length does not need to comply with existing applications.To obtain a position data output being compatible to the BiSS B protocol parameter ENCDS=0does switch off the CDS bit,without a replacement by a zero bit.Thus, the output data length is shorten by one bit and register communication is limited to the direction of the master to the slave.The bidirectional BiSS C register commu-nication must be enabled by setting ENCDS=1.

Other storage areas are addressed dynamically and in blocks.BiSS addresses0x00to0x3F aim for a reg-ister bank consisting of64bytes,the physical storage address of which is determined by Bank Select n.iC-NQC supports up to16storage banks,making it possible to use an8-bit EEPROM to its full capacity. There is therefore also enough storage space for an ID plate(EDS)and OEM data.Information regarding memory map and addressing via BiSS is given on page25).Internal Reset FunctionA write access at RAM address0x00(BiSS address 0x00with Bank Select n=0)triggers an internal reset. Based on the current configuration in the RAM,iC-NQC restarts without reading the EEPROM.The con-figured interface timeout and write protect settings be-come active,the period counter is set to zero and any stored configuration errors are deleted.The data out-put via SLO and the incremental signals at A,B and Z are released.Providing no amplitude error is present, the converter again counts up from an angle value of zero to the current angle position.Short BiSS TimeoutFor programming via the I/O interface iC-NQC has a short BiSS timeout function according to the descrip-tion of the BiSS C protocol(see page19,T able2,El. Char.no.6).Rev D3,Page21/30Regardless of register protection settings a short time-out of typically1.8µs can be temporarily activated by writing value0x07to address0x7C(address124d).A controller can then transmit the device configuration over a shorter period.Table42:Short timeout(via BiSS device ID)The value written to address0x7C is also transferred to the EEPROM,provided an EEPROM has been con-nected up and is available.On reading address0x7C the byte stored in the EEP-ROM is output as part of the BiSS device ID.Here, high-order bits7:3are part of the manufacturer’s ID; low-order bits2:0act as an indicator of the timeout op-tions(regular or short timeout,see T able42).Rev D3,Page22/30iC-NQC can transmit position data in SSI protocol mode;the parameters described in the following give the necessary settings andoptions.Figure 17:Example line signal (SSI)Table 43:Protocol versionTable 44:Timeout configuration for SSIT able 45:Period counter for SSI data outputT able

SCL and SDA and enables read and write access to a serial EEPROM with I2C interface(with at least128 bytes,5V type with a3.3V function; e.g.24C01, 24C02,24C08and maximal24C16).The configuration data in the EEPROM,of addresses 0x00to0x0F,is secured by a CRC check value to ad-dress0x0F.When the device is powered up,the ad-dress range from0x00to0x0F is mapped onto iC-NQC’s configuration RAM.The higher memory area contains BiSS C slave registers and optional memory banks available to the sensor system.The register access to the configuration data and the memory banks1to7(intended for EDS)can be re-stricted by parameter RPL.N.B.When writing configuration data to the EEPROM (BiSS addresses0x10to0x1F)a wait time of at least 4ms must be allowed after each register.Example of CRC Calculation

addressingStartup With A Configured EEPROMAfter the supply has been turned on (power-on reset),iC-NQC reads the configuration data from the EEP-ROM.During this phase it actively keeps error pin NERR at a low signal (open drain output),and data output SLO and the incremental signals at A,B and Z at a high signal.After a successful CRC the data output to SLO and to the incremental A,B,and Z outputs is released and the error indication at pin NERR reset;an external pull-up resistor at pin NERR can supply a high signal.iC-NQC then switches to normal operation and determines the current angle position,providing that a sensor is con-nected up to it and there is no amplitude error (or this is deactivated).Should the CRC prove unsuccessful due to a data er-ror (disrupted transmission,no EEPROM or the EEP-ROM is not programmed),the configuration phase is automatically repeated.After a third failed attempt,the procedure is aborted and error pin NERR displays a permanent low;data output SLO and the incremental signals at A,B and Z remain at a high signal.Startup Without An EEPROMThe configuration RAM contains random values after startup;iC-NQC does not have a default configuration.Error pin NERR shows a low signal (open drain out-put);data output SLO and the incremental signals at A,B and Z indicate a high signal.T o reduce the device configuration time,a short time-out of 3µs maximum (cf.TIMO =1and TOA =0)can be temporarily activated by writing value 0x07to ad-dress 0x7C (address 124d).When operated without an EEPROM,iC-NQC does not respond to higher addresses -with the exception of the BiSS addresses reserved for manufacturer and device IDs (0x78to 0x7F).This address area supplies the chip version from the ROM.Initialization After Configuration FailureSo that it is always possible to talk to iC-NQC via the I/O interface,iC-NQC first ignores the register values of TIMO,TOA,RPL and TMA.Instead,iC-NQC ap-plies the longest timeout (cf.TIMO =0and TOA =0),ignores safety settings (cf.RPL =0x0)and evaluates the BiSS register communication (CDM bit from the CD data channel).Rev D3,Page 26/30During this phase regular bidirectional BiSS register communication is not yet possible,as data output SLO is permanently kept at high.Writing the configuration to RAM addresses 0x01to 0x0C and to address 0x00must be executed without evaluating a reply.Data in-put SLI is ignored;iC-NQC always uses slave ID 0.lowing figures each show a single cycle with CDM =0and CDM =1.A wide range of 100ns to 12.5µs is per-missible for clock period T(MA);the timeout must last at least 30µs.A complete write cycle requires 14cycles at CDM =0Rev D3,Page 27/30or current source signals with ground ref-current source outputs,such as for op-toencoder

The systeminterface, SDRAM state machine, and SDRAM interface logic fits into this device with theutilization results shown in Table3.Table 3: CoolRunner-II Design UtilizationParameter Used Available% UtilizationI/O Pins8610086%Macrocells10212880%Product Terms18044840%Registers10012878%Function Block Inputs12632039%System InterfaceThe SDRAM design described in this document includes a generic system interface. Thesystem interface illustrates the basic control signals needed for the SDRAM logic block. Thesesignals include a system clock, reset, 24-bit address bus, 16-bit data bus, and 4-bit commandbus. Excluding the system clock, all signals are asynchronous and registered in the CPLD.Modeling of the system interface in this design is done with testbench logic. The testbench isresponsible for generating the address, data and command signals for any operation with the XAPP394 (v1.1) December 1, 2003Expanding I/O Expanding I/O Designers faced with accommodating a keypad requiring more I/O might find their existingprocessor (or ASIC) does not have enough GPIO ports. One solution is to use a CPLD as anI/O expander that reduces the I/O requirement of the processor.Figure2 shows a CPLD interfacing to the keypad rows/columns on one side, and theprocessor’s available GPIO on the other. In this example, an 8 x 8 keypad requires the samenumber of processor GPIO ports as the 4 x 4 keypad (actually one less) when a CPLD is used.Without a CPLD, the processor would require 16 GPIO ports instead of 7.Figure 2: CPLD Expands I/O and Reduces the Processor’s GPIOScanning and Encoding Besides reducing the processor’s GPIO requirements, the CPLD also scans the rows and monitors the columns for a change in state. When a key is pressed, the CPLD stops scanning and immediately sends an encoded word out to the processor. The encoded word indicates which key was pressed.In the example shown in Figure2, there are six bits used to represent the encoded word. Six bits provides 26 or 64 different values each representing a different key. However, one value needs to be used to represent the state when no keys are pressed. Therefore, only 63 keys can be represented in this example.All 64 keys most likely would not be needed in a typical application. If they were, there are many options with a programmable CPLD. For instance, a CPLD could generate an enable signal to the processor that would indicate when a key is being pressed (that is, when the encoded value was valid). This would require one more GPIO on the processor.The processor is still required to monitor for changes on its GPIO, only it would not have to deduce which key was pressed since this information is encoded in the six bit word. Debounce will also be required. This can be performed in the CPLD or the processor. Performing this inthe processor would keep the size of the CPLD to a minimum.XAPP512 (v1.1) May 6, 2005。
