cf745电路工作原理CF745是一种基于Microchip技术的8位Flash单片机，以下是其工作原理：1. 时钟信号：CF745需要一个时钟信号来同步其内部操作。

时钟信号可以通过外部晶体振荡器提供，或者通过内部RC振荡器生成。

2. 存储器：CF745具有内部Flash存储器和RAM存储器。

Flash存储器用于存储程序代码和常量数据，RAM存储器用于存储临时变量和数据。

3. 输入/输出：CF745具有多个通用输入/输出引脚，可以与外部电路或外设连接。

通过配置寄存器，可以将这些引脚配置为输入模式或输出模式，并设置相应的电平。

4. 中断：CF745支持多级中断，并且具有多个中断源可供选择。

当外部事件触发中断源时，CF745将中断标志设置为高，并跳转到相应的中断服务程序执行。

5. 定时器：CF745具有多个定时器，可用于生成定时延迟、测量时间间隔和产生PWM信号等功能。

通过配置寄存器，可以设置定时器的计数模式、时钟源和预分频器等参数。

6. 串口通信：CF745通过串口进行与外部设备的通信。

它支持多种串口协议，如UART、SPI和I2C等。

通过配置寄存器，可以设置串口的波特率、数据位数、校验位和停止位等参数。

7. 算术逻辑单元(ALU)：CF745具有一组算术逻辑单元，用于执行算术和逻辑运算。

它支持常见的算术操作（如加法、减法）和逻辑操作（如与、或）等。

8. 控制单元：CF745的控制单元负责对指令进行解码和执行。

它从存储器中读取指令，并根据指令执行相应的操作。

控制单元还管理中断、定时器和外设等各个模块的协调工作。

通过上述组成部分的协同工作，CF745能够执行各种任务，包括数据处理、外设控制、通信和定时等。

它是一种功能强大的单片机，被广泛应用于各种应用领域，如工业自动化、智能家居和消费电子产品等。

These parts operate from a single 3 V or 5 V power supply and use advanced design techniques to achieve very low power dissipation at throughput rates up to 1 MSPS. The SAR architecture of these parts ensures that there are no pipeline delays.The parts contain a low noise, wide bandwidth, differential track-and-hold amplifier (T/H) that can handle input frequencies up to 3.5 MHz. The reference voltage is applied externally to the V REF pin and can be varied from 100 mV to 3.5 V depending on the power supply and what suits the application. The value of the reference voltage determines the common-mode voltage range of the part. With this truly differential input structure and variable reference input, the user can select a variety of input ranges and bias points.The conversion process and data acquisition are controlled using CS and the serial clock, allowing the device to interface with microprocessors or DSPs. The input signals are sampledFUNCTIONAL BLOCK DIAGRAM351-A-1V REFGNDVV IN+V IN–Figure 1.on the falling edge of CS; the conversion is also initiated at this point. The SAR architecture of these parts ensures that there are no pipeline delays. The AD7440 and the AD7450A use ad-vanced design techniques to achieve very low power dissipation at high throughput rates.PRODUCT HIGHLIGHTS1.Operation with either 3 V or 5 V power supplies.2.High throughput with low power consumption.With a 3 V supply, the AD7440/AD7450A offer 4 mWmax power consumption for 1 MSPS throughput.3.Fully differential analog input.4.Flexible power/serial clock speed management.The conversion rate is determined by the serial clock,allowing the power to be reduced as the conversion timeis reduced through the serial clock speed increase. Theseparts also feature a shutdown mode to maximize powerefficiency at lower throughput rates.5.Variable voltage reference input.6.No pipeline delay.7.Accurate control of the sampling instant via a CS input andonce-off conversion control.8.ENOB > eight bits typically with 100 mV reference.1 Protected by U.S. Patent Number 6,681,332.AD7440/AD7450ARev.

All input signals are specified with tr = tf = 5 ns (10% to 90% of V DD ) and timed from a voltage level of 1.6 V . See Figure 2, Figure 3, and the Serial Interface section.Table 3. V DD = 2.7 V to 3.6 V, f SCLK = 18 MHz, f S = 1 MSPS, V REF = 2.0 V; V DD = 4.75 V to 5.25 V, f SCLK = 18 MHz, f S = 1 MSPS,11 Common-mode voltage.2Mark/space ratio for the SCLK input is 40/60 to 60/40. 3Measured with the load circuit of Figure 4 and defined as the time required for the output to cross 0.8 V or 2.4 V with V DD = 5 V or 0.4 V or 2.0 V for V DD = 3 V. 4t 8 is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 4. The measured number is then extrapolated back to remove the effects of charging or discharging the 25 pF capacitor. This means that the time, t 8, quoted in the Timing Specifications is the true bus relinquish time of the part and is independent of the bus loading. 5See Power-Up Time section.CSSCLKFigure 2.

C | Page 10 of 28TERMINOLOGYSignal-to-(Noise + Distortion) RatioThis is the measured ratio of signal to (noise + distortion) at the output of the ADC. The signal is the rms amplitude of the fundamental. Noise is the sum of all nonfundamental signals up to half the sampling frequency (f S /2), excluding dc. The ratio is dependent on the number of quantization levels in the digitization process; the more levels, the smaller the quanti-zation noise. The theoretical signal-to-(noise + distortion) ratio for an ideal N-bit converter with a sine wave input is given by the following:Signal-to-(Noise + Distortion) = (6.02N + 1.76)dB . Thus for a 12-bit converter, this is 74 dB; and for a 10-bit converter, this is 62 dB.Total Harmonic Distortion (THD)THD is the ratio of the rms sum of harmonics to the fundamental. For the AD7440/AD7450A, it is defined as12625242322V V V V V THD ++++=log20)dB (where V 1 is the rms amplitude of the fundamental and V 2, V 3, V 4, V 5, and V 6 are the rms amplitudes of the second to the sixth harmonics.Peak Harmonic or Spurious NoisePeak harmonic (spurious noise) is the ratio of the rms value of the next largest component in the ADC output spectrum (up to f S /2 and excluding dc) to the rms value of the fundamental. Normally, the value of this specification is determined by the largest harmonic in the spectrum, but for ADCs where the harmonics are buried in the noise floor, it is a noise peak.Intermodulation DistortionWith inputs consisting of sine waves at two frequencies,fa and fb, any active device with nonlinearities creates distortion products at the sum and difference frequencies of mfa ± nfb where m, n = 0, 1, 2, 3, and so on. Intermodulation distortion terms are those for which neither m nor n is equal to 0. For example, the second-order terms include (fa + fb) and (fa – fb), while the third-order terms include (2fa + fb), (2fa – fb), (fa + 2fb), and (fa – 2fb).The AD7440/AD7450A is tested using the CCIF standard of two input frequencies near the top end of the input bandwidth. In this case, the second-order terms are distanced in frequency from the original sine waves, while the third-order terms are at a frequency close to the input frequencies. As a result, the second- and third-order terms are specified separately. The calculation of theintermodulation distortion is as per the THD specification, where it is the ratio of the rms sum of the individual distortion products to the rms amplitude of the sum of the fundamentals, expressed in dB.Aperture DelayThis is the amount of time from the leading edge of the sampling clock until the ADC actually takes the sample.Aperture JitterThis is the sample-to-sample variation in the effective point in time at which the actual sample is taken.Full Power BandwidthThe full power bandwidth of an ADC is the input frequency at which the amplitude of the reconstructed fundamental is reduced by 0.1 dB or 3 dB for a full-scale input.Common-Mode Rejection Ratio (CMRR)The common-mode rejection ratio is the ratio of the power in the ADC output at full-scale frequency, f , to the power of a 100 mV p-p sine wave applied to the common-mode voltage of V IN+ and V IN– of frequency f S as follows:CMRR (dB) = 10 log (Pf/Pfs )Pf is the power at the frequency f in the ADC output; Pfs is the power at frequency f S in the ADC output.Integral Nonlinearity (INL)This is the maximum deviation from a straight line passing through the endpoints of the ADC transfer function.Differential Nonlinearity (DNL)This is the difference between the measured and the ideal 1 LSB change between any two adjacent codes in the ADC.Zero-Code ErrorThis is the deviation of the midscale code transition(111...111 to 000...000) from the ideal V IN+ − V IN– (i.e., 0 LSB).Positive Gain ErrorThis is the deviation of the last code transition (011...110 to 011...111) from the ideal V IN+ – V IN– (i.e., +V REF − 1 LSB), after the zero code error has been adjusted out.Negative Gain ErrorThis is the deviation of the first code transition (100...000 to 100...001) from the ideal VIN+ − VIN– (i.e., –VREF + 1 LSB), after the zero code error has been adjusted out.Track-and-Hold Acquisition TimeThe track-and-hold acquisition time is the minimum time required for the track-and-hold amplifier to remain in track mode for its output to reach and settle to within 0.5 LSB of the applied input signal.元器件交易网AD7440/AD7450APower Supply Rejection Ratio (PSRR)The power supply rejection ratio is the ratio of the power in the ADC output at full-scale frequency, f, to the power of a 100 mV p-p sine wave applied to the ADC VDD supply of frequency fS. The frequency of this input varies from 1 kHz to 1 MHz. PSRR (dB) = 10log(Pf/PfS) Pf is the power at frequency f in the ADC output; Pfs is the power at frequency fS in the ADC output.Rev.

C | Page 14 of 2803051-A-022元器件交易网AD7440/AD7450A CIRCUIT INFORMATIONThe AD7440/AD7450A are 10-bit and 12-bit fast, low power, single-supply, successive approximation analog-to-digital converters (ADCs). They can operate with a 5 V or 3 V power supply and are capable of throughput rates up to 1 MSPS when supplied with an 18 MHz SCLK. They require an external reference to be applied to the VREF pin, with the value of the reference chosen depending on the power supply and what suits the application. When they are operated with a 5 V supply, the maximum reference that can be applied is 3.5 V. When they are operated with a 3 V supply, the maximum reference that can be applied is 2.2 V (see the Reference section). The AD7440/AD7450A have an on-chip differential track-andhold amplifier, a successive approximation (SAR) ADC, and a serial interface housed in either an 8-lead SOT-23 or an MSOP package. The serial clock input accesses data from the part and provides the clock source for the successive approximation ADC. The AD7440/AD7450A feature a power-down option for reduced power consumption between conversions. The powerdown feature is implemented across the standard serial interface as described in the Modes of Operation section. When the ADC starts a conversion (Figure 24), SW3 opens and SW1 and SW2 move to Position B, causing the comparator to become unbalanced. Both inputs are disconnected once the conversion begins. The control logic and the charge redistribution DACs are used to add and subtract fixed amounts of charge from the sampling capacitor arrays to bring the comparator back into a balanced condition. When the comparator is rebalanced, the conversion is complete. The control logic generates the ADC’s output code. The output impedances of the sources driving the VIN+ and the VIN– pins must be matched; otherwise, the two inputs have different settling times, resulting in errors.CAPACITIVE DAC B VIN+ A A B CS SW1 SW3 VIN– SW2 VREF CS COMPARATOR CAPACITIVE DAC03051-A-024CONTROL LOGICFigure 24. ADC Conversion PhaseCONVERTER OPERATIONThe AD7440/AD7450A are successive approximation ADCs based around two capacitive DACs. Figure 23 and Figure 24 show simplified schematics of the ADC in acquisition and conversion phase, respectively. The ADC is comprised of control logic, an SAR, and two capacitive DACs. In Figure 23 (acquisition phase), SW3 is closed, SW1 and SW2 are in Position A, the comparator is held in a balanced condition, and the sampling capacitor arrays acquire the differential signal on the input.CAPACITIVE DAC B VIN+ A A B CS SW1 SW3 VIN– SW2 VREF CS COMPARATOR CAPACITIVE DAC03051-A-023ADC TRANSFER FUNCTIONThe output coding for the AD7440/AD7450A is twos complement.

Shared-Queue QoS PoliciesIn This SectionThis section provides information to configure shared-queue QoS policies using the commandline interface.Topics in this section include:•Overview on page 690•Basic Configurations on page 697•Default Shared Queue Policy Values on page 702OverviewOverviewShared-queue QoS policies can be implemented to facilitate queue consumption on the router. It isespecially useful when VPLS, IES, and VPRN services are scaled to very high numbers. Instead ofallocating multiple hardware queues for each unicast queue defined in a SAP ingress QoS policy,SAPs with the shared-queuing feature enabled only allocate one hardware queue for each SAPingress QoS policy unicast queue.However, as a trade-off, the total amount of traffic throughput at the ingress of the node is reducedbecause any ingress packet serviced by a shared-queuing SAP is recirculated for furtherprocessing. This can reduce the bandwidth by half. Shared-queuing can add latency. Networkplanners should consider these restrictions while trying to scale services on the router.Multipoint Shared QueuingMultipoint shared queuing is supported to minimize the number of multipoint queues created foringress VPLS, IES or VPRN SAPs or ingress subscriber SLA profiles. Normally, ingressmultipoint packets are handled by multipoint queues created for each SAP or subscriber SLAprofile instance. In some instances, the number of SAPs or SLA profile instances are sufficient forthe in use multipoint queues to represent many thousands of queues on an ingress forwardingplane. If multipoint shared queuing is enabled for the SAPs or SLA profile instances on theforwarding plane, the multipoint queues are not created. Instead, the ingress multipoint packets arehandled by the unicast queue mapped to the forwarding class of the multipoint packet.Functionally, multipoint shared queuing is a superset of shared queuing. With shared queuing on aSAP or SLA profile instance, only unicast packets are processed twice, once for the initial servicelevel queuing and a second time for switch fabric destination queuing. Shared queuing does notaffect multipoint packet handling. Multipoint packet handling in normal (service queuing) is thesame as shared queuing. When multipoint shared queuing is enabled, shared queuing for unicastpackets is automatically enabled.Ingress Queuing Modes of OperationThree modes of ingress SAP queuing are supported for multipoint services (IES, VPLS andVPRN); service, shared, and multipoint shared. The same ingress queuing options are available forIES and VPLS subscriber SLA profile instance queuing.Shared Queue QoS PoliciesIngress Service QueuingNormal or service queuing is the default mode of operation for SAP ingress queuing. Service queuing preserves ingress forwarding bandwidth by allowing a service queue defined in an ingress SAP QoS policy to be represented by a group of hardware queues. A hardware queue is created for each switch fabric destination to which the logical service queue must forward packets. For a VPLS SAP with two ingress unicast service queues, two hardware queues are used for eachdestination forwarding engine the VPLS SAP is forwarding to. If three switch fabric destinations are involved, six queues are allocated (2 unicast service queues multiplied by 3 destination forwarding complexes equals six hardware queues). Figure 35 demonstrates unicast hardware queue expansion. Service multipoint queues in the ingress SAP QoS policy are not expanded to multiple hardware queues, each service multipoint queue defined on the SAP equates to a single hardware queue to the switch fabric.When multiple hardware queues represent a single logical service queue, the system automatically monitors the offered load and forwarding rate of each hardware queue. Based on the monitored state of each hardware queue, the system imposes an individual CIR and PIR rate for each queue that provides an overall aggregate CIR and PIR reflective of what is provisioned on the service queue.Figure 35: Unicast Service Queue Mapping to Multiple Destination Based Hardware Queueson ClassFig_22Multipoint Shared QueuingIngress Shared QueuingTo avoid the hardware queue expansion issues associated with normal service based queuing, thesystem allows an ingress logical service queue to map to a single hardware queue when sharedqueuing is enabled. Shared queuing uses two passes through the ingress forwarding plane toseparate ingress per service queuing from the destination switch fabric queuing. In the case ofshared queuing, ingress unicast service queues are created one-for-one relative to hardwarequeues. Each hardware queue representing a service queue is mapped to a special destination inthe traffic manager that ‘forwards’ the packet back to the ingress forwarding plane allowing asecond pass through the traffic manager. In the second pass, the packet is placed into a ‘shared’queue for the destination forwarding plane. The shared queues are used by all services configuredfor shared queuing.When the first SAP or SLA profile instance is configured for shared queuing on an ingressforwarding plane, the system allocates eight hardware queues per available destination forwardingplane, one queue per forwarding class. Twenty-four hardware queues are also allocated formultipoint shared traffic, but that is discussed in the following section. The shared queueparameters that define the relative operation of the forwarding class queues are derived from theShared Queue policy defined in the QoS CLI node. Figure 36 demonstrates shared unicastqueuing. SAP or SLA profile instance multipoint queuing is not affected by enabling sharedqueuing. Multipoint queues are still created as defined in the ingress SAP QoS policy and ingressmultipoint packets only traverse the ingress forwarding plane a single time.Enabling shared queuing may affect ingress performance due to double packet processing throughthe service and shared queues.Shared Queue QoS PoliciesFigure 36: Unicast Service Queuing With Shared Queuing EnabledMultipoint Shared QueuingMultipoint Service Queue isrepresentated by a singleHardware Queue (Single Pass)Fig_24 Figure 37: Multipoint Queue Behavior with Shared Queuing EnabledShared Queue QoS PoliciesIngress Multipoint Shared QueuingIngress multipoint shared queuing is a variation to the unicast shared queuing defined in IngressShared Queuing on page 692. Ingress unicast service queues are mapped one-for-one withhardware queues and unicast packets traverse the ingress forwarding plane twice. In addition to theabove, the multipoint queues defined in the ingress SAP QoS policy are not created. Instead,multipoint packets (broadcast, multicast and unknown unicast destined) are treated to the samedual pass ingress forwarding plane processing as unicast packets. In the first pass, the forwardingplane uses the unicast queue mappings for each forwarding plane. The second pass uses themultipoint shared queues to forward the packet to the switch fabric for special replication to allegress forwarding planes that need to process the packet.The benefit of defining multipoint shared queuing is the savings of the multipoint queues perservice. By using the unicast queues in the first pass and then the aggregate shared queues in thesecond pass, per service multipoint queues are not required. The predominant scenario wheremultipoint shared queuing may be required is with subscriber managed QoS environments using asubscriber per SAP model. Usually, ingress multipoint traffic is minimal per subscriber and theextra multipoint queues for each subscriber reduces the overall subscriber density on the ingressforwarding plane. Multipoint shared queuing eliminates the multipoint queues sparing hardwarequeues for better subscriber density. Figure 2.3 demonstrates multipoint shared queuing.One caveat of enabling multipoint shared queuing is that multipoint packets are no longermanaged per service (although the unicast forwarding queues may provide limit benefit in thisarea). Multipoint packets in a multipoint service (VPLS, IES and VPRN) use significant resourcesin the system, consuming ingress forwarding plane multicast bandwidth and egress replicationbandwidth. Usually, the per service unicast forwarding queues are not rate limited to a degree thatallows adequate management of multipoint packets traversing them when multipoint sharedqueuing is enabled. It is possible to minimize the amount of aggregate multipoint bandwidth bysetting restrictions on the multipoint queue parameters in the QoS nodes Shared Queue policy.Aggregate multipoint traffic can be managed per forwarding class for each of the three forwardingtypes (broadcast, multicast or unknown unicast – broadcast and unknown unicast are only used byVPLS).Another caveat for multipoint shared queuing is that multipoint traffic now consumes double theingress forwarding plane bandwidth due to dual pass ingress processing.Multipoint Shared QueuingFigure 38: Multipoint Shared Queuing Using First Pass Unicast QueuesNote that multipoint shared queuing cannot be enabled on the following services:•Epipe •Apipe •Fpipe •Ipipe •Routed COFor information about the tasks and commands necessary to access the command line interface and to configure and maintain your router, refer to CLI Usage chapter in the Basic System Configuration Guide.Unicast Service Queue is representated by a singleHardware Queue But Dual Pass Fig_25Shared Queue QoS PoliciesBasic ConfigurationsThe default shared queue QoS policy conforms to the following:•There is only one default shared queue policy in the system.•The default shared queue policy has fixed forwarding classes, queues and FC-queuemapping, which cannot be modified, added, or deleted.The only configurable entities in the default shared queue policy are the queue attributes, queuepriority, and the description string.

DS7400-XI报警主机的简单调试和编程方法当入侵报警系统设备之间连接好之后，主要的调试和编程设置都是在键盘上完成的。

DS7400XI 报警控制系统主机是一种大型的防火/防盗报警系统。

它可与各种防盗探测器及防火探测器相连接。

主机板自带8 个防区，可扩充240 个防区（4.0 版）。

一共248个防区。

扩充采用两线总线方式。

扩充设备的类型有8 防区，扩展模块DS7432、单防区扩展模块DS7457i、单防区带输出的模块DS7465i、双防区扩展模块DS7460i、DS3MX、DS6MX 以及各种带地址码的红外，门磁，烟感器等。

总线驱动器可采用DS7430（单总线）或DS7436（双总线）。

在我们实验室里报警主机主要由自带8防区的主机板，总线驱动器DS7436（直接嵌在主机板上），单防区扩展模块DS7457i，前端红外对射探测器自带8防区的主机板 1个总线驱动器DS7436 1个单防区扩展模块DS7457i 2块前端红外对射探测器 2对在编程之前我们要对DS7457i地址码进行设置DS7457i 上有八组手动拨码开关，用来设置DS7457i 的防区号。

方法是将八组开关分别对应的数字相加，所得出的数就是防区号。

并把需要相加的数对应的开关拨到ON 的位置。

如图所示的开关位置表示33 防区。

这里要说明一下这里编号必须要大于等于9，因为前8个地址已经被主机板上的8个防区所占据。

调试之前暂时不要接入探测设备这样便于在调试过程中排除探测器问题的干扰前期的准备做完之后就可以进入编程调试阶段第一步：闭合接入交流电源开关（会听到“嘟”的一声）检查前端探测器电路是否是闭路状态如果不是请恢复到闭路状态在键盘上输入9876#0输入4058 01# （对原先设置的程序清空恢复到出厂时设置便于对系统重新编程） 综合编程地址（0000）输入0000 14#系统自动跳转到0001确定防区功能编程地址（0001-0030）输入22#（输入完后地址自动跳转到0002）这里输入的22就是数据1和数据2中分别输入数字2表示防区功能是:连续报警声输出，开路报警24小时防区。
