The device provides 14 bytes of real-time clock/calendar, alarm, and control/status registers and 114 bytes of nonvolatile, battery-backed static RAM. A time-of-day alarm, three maskable interrupts with a common interrupt output, and a programmable square-wave output are available. The DS12R885 also operates in either 24-hour or 12-hour format with an AM/PM indicator. A precision temperature-compensat-ed circuit monitors the status of V CC . If a primary power-supply failure is detected, the device automati-cally switches to a backup supply. The backup supply input supports either a rechargeable battery or a super cap, and includes an integrated trickle charger. The trickle charger is always enabled. The DS12R885 is accessed through a multiplexed address/data bus that supports Intel and Motorola modes.The DS12R887 is a surface-mount package using the DS12R885 die, a 32.768kH z crystal, and a recharge-able battery. The device provides a real-time clock/cal-endar, one time-of-day alarm, three maskable interrupts with a common interrupt output, a programmable square wave, and 114 bytes of nonvolatile, battery-backed static RAM. The date at the end of the month is automatically adjusted for months with fewer than 31days, including correction for leap years. It also oper-ates in either 24-hour or 12-hour format with an AM/PM indicator. A precision temperature-compensated circuit monitors the status of V CC . If a primary power failure is detected, the device automatically switches to a back-up battery included in the package. The device is accessed through a multiplexed byte-wide interface,which supports both Intel and Motorola modes.The DS12CR887 EDIP integrates a DS12R885 die with a crystal and battery. The charging circuit on theDS12R885 die is disabled. The battery has sufficient capacity to power the oscillator and registers for five years in the absence of V CC at +25°C.The DS12R887 BGA includes a crystal and a recharge-able battery. A fully charged battery can power the oscil-lator and registers (typical current at +25°C) in the absence of V CC for approximately 11 days (10% of capacity consumed) or 98 days (90% capacity con-sumed). When the discharge depth is 10% of capacity,the battery can be recharged up to 1,000 times. If the dis-charge depth is 90% of capacity, the battery can be recharged up to 30 times. Thus, the life of the device would be approximately 30 years (11 days X 1,000cycles) or 8 years (98 days x 30 cycles). Charging time to full capacity is approximately two days with V CC applied.Please consult related application notes for detailed information on battery lifetime versus depth of dis-charge, and expected product lifetime based upon battery cycles.Oscillator CircuitThe DS12R885 uses an external 32.768kHz crystal. The oscillator circuit does not require any external resistors or capacitors to operate. Table 1 specifies several crys-tal parameters for the external crystal. Figure 1 shows a functional schematic of the oscillator circuit. An enable bit in the control register controls the oscillator.Oscillator startup times are highly dependent upon crystal characteristics, PC board leakage, and layout.High ESR and excessive capacitive loads are the major contributors to long startup times. A circuit using a crystal with the recommended characteristics and proper layout usually starts within one second.An external 32.768kH z oscillator can also drive the DS12R885. In this configuration, the X1 pin is connected to the external oscillator signal and the X2 pin is floated.Figure 1. Oscillator Circuit Showing Internal Bias NetworkTable 1. Crystal Specifications**The crystal, traces, and crystal input pins should be isolated from RF generating signals. Refer to Application Note 58:Crystal Considerations for Dallas Real-Time Clocks for additional specifications.Clock Accuracy The accuracy of the clock is dependent upon the accu-racy of the crystal and the accuracy of the match between the capacitive load of the oscillator circuit and the capacitive load for which the crystal was trimmed. Additional error is added by crystal frequency drift caused by temperature shifts. External circuit noise cou-pled into the oscillator circuit can result in the clock run-ning fast. Figure2 shows a typical PC board layout for isolation of the crystal and oscillator from noise. Refer to Application Note 58: Crystal Considerations with Dallas Real-Time Clocks for more detailed information.The DS12R887 and DS12CR887 are calibrated at the factory to an accuracy of ±1 minute per month at +25°C during data-retention time for the period t OR.Power-Down/Power-UpConsiderations The real-time clock continues to operate regardless of the V CC input level, and the RAM and alarm memory locations remain nonvolatile. V BACKUP must remain within the minimum and maximum limits when V CC is not applied. When V CC is applied and exceeds V PF (power-fail trip point), the device becomes accessible after t REC—if the oscillator is running and the oscillator countdown chain is not in reset (Register A). This time allows the system to stablize after power is applied. If the oscillator is not enabled, the oscillator-enable bit is enabled on power-up, and the device becomes imme-diately accessible.Time, Calendar, and AlarmLocations The time and calendar information is obtained by read-ing the appropriate register bytes. The time, calendar, and alarm are set or initialized by writing the appropri-ate register bytes. The contents of the 10 time, calen-dar, and alarm bytes can be either binary or binary-coded decimal (BCD) format.The day-of-week register increments at midnight, incre-menting from 1 through 7. The day-of-week register is used by the daylight savings function, so the value 1 is defined as Sunday. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including correction for leap years.Before writing the internal time, calendar, and alarm reg-isters, the SET bit in Register B should be written to logic1 to prevent updates from occurring while access isbeing attempted. In addition to writing the 10 time, calen-dar, and alarm registers in a selected format (binary or BCD), the data mode bit (DM) of Register B must be setto the appropriate logic level. All 10 time, calendar, andalarm bytes must use the same data mode. The SET bitin Register B should be cleared after the data mode bithas been written to allow the RTC to update the time and calendar bytes. Once initialized, the RTC makes all updates in the selected mode. The data mode cannot be changed without reinitializing the 10 data bytes. Tables2A and 2B show the BCD and binary formats of the time, calendar, and alarm locations.The 24-12 bit cannot be changed without reinitializing thehour locations. When the 12-hour format is selected, the higher-order bit of the hours byte represents PM when itis logic 1. The time, calendar, and alarm bytes are always accessible because they are double-buffered. Once per second the seven bytes are advanced by one secondand checked for an alarm condition.If a read of the time and calendar data occurs duringan update, a problem exists where seconds, minutes, hours, etc., may not correlate. The probability of read-ing incorrect time and calendar data is low. Several methods of avoiding any possible incorrect time and calendar reads are covered later in this text.DS12R885/DS12CR887/DS12R887D S 12R 885/D S 12C R 887/D S 12R 887The three alarm bytes can be used in two ways. First,when the alarm time is written in the appropriate hours,minutes, and seconds alarm locations, the alarm inter-rupt is initiated at the specified time each day, if the alarm-enable bit is high. In this mode, the “0” bits in the alarm registers and the corresponding time registers must always be written to 0 (Table 2A and 2B). Writing the 0 bits in the alarm and/or time registers to 1 can result in undefined operation.The second use condition is to insert a “don’t care”state in one or more of the three alarm bytes. The don’t-care code is any hexadecimal value from C0 to FF. The two most significant bits of each byte set the don’t-carecondition when at logic 1. An alarm is generated each hour when the don’t-care bits are set in the hours byte.Similarly, an alarm is generated every minute with don’t-care codes in the hours and minute alarm bytes.The don’t-care codes in all three alarm bytes create an interrupt every second.All 128 bytes can be directly written or read, except for the following:1)Registers C and D are read-only.2)Bit 7 of register A is read-only.3)The MSB of the seconds byte is read-only.Note: Unless otherwise specified, the state of the registers is not defined when power is first applied. Except for the seconds regis-ter, 0 bits in the time and date registers can be written to 1, but may be modified when the clock updates. 0 bits should always be written to 0 except for alarm mask bits.Note: Unless otherwise specified, the state of the registers is not defined when power is first applied. Except for the seconds regis-ter, 0 bits in the time and date registers can be written to 1, but may be modified when the clock updates. 0 bits should always be written to 0 except for alarm mask bits.DS12R885/DS12CR887/DS12R887D S 12R 885/D S 12C R 887/D S 12R 887flag that can be monitored. When the UIP bit is a 1, the update transfer occurs soon. When UIP is a 0, the update transfer does not occur for at least 244µs. The time, calendar, and alarm information in RAM is fully available for access when the UIP bit is 0. The UIP bit is read-only and is not affected by RESET . Writing the SET bit in Register B to a 1 inhibits any update transfer and clears the UIP status bit.Bits 6, 5, and 4: DV2, DV1, DV0. These three bits are used to turn the oscillator on or off and to reset the countdown chain. A pattern of 010 is the only combina-tion of bits that turn the oscillator on and allow the RTC to keep time. A pattern of 11x enables the oscillator but holds the countdown chain in reset. The next update occurs at 500ms after a pattern of 010 is written to DV0,DV1, and DV2.These four rate-selection bits select one of the 13 taps on the 15-stage divider or disable the divider output.The tap selected can be used to generate an output square wave (SQW pin) and/or a periodic interrupt. The user can do one of the following:1)Enable the interrupt with the PIE bit;2)Enable the SQW output pin with the SQWE bit;3)Enable both at the same time and the same rate;or4)Enable neither.Table 3 lists the periodic interrupt rates and the square-wave frequencies that can be chosen with the RS bits.These four read/write bits are not affected by RESET .Control Register AControl RegistersThe DS12R885 has four control registers that are accessible at all times, even during the update cycle.DS12R885/DS12CR887/DS12R887Bit 7: SET. When the SET bit is 0, the update transfer functions normally by advancing the counts once per second. When the SET bit is written to 1, any update transfer is inhibited, and the program can initialize the time and calendar bytes without an update occurring in the midst of initializing. Read cycles can be executed in a similar manner. SET is a read/write bit and is not affected by RESET or internal functions of the DS12R885.Bit 6: Periodic Interrupt Enable (PIE). The PIE bit is a read/write bit that allows the periodic interrupt flag (PF) bit in Register C to drive the IRQ pin low. When the PIE bit is set to 1, periodic interrupts are generated by driving the IRQ pin low at a rate specified by the RS3–RS0 bits of Register A. A 0 in the PIE bit blocks the IRQ output from being driven by a periodic interrupt, but the PF bit is still set at the periodic rate. PIE is not modified by any internal DS12R885 functions, but is cleared to 0 on RESET .Bit 5: Alarm Interrupt Enable (AIE).This bit is a read/write bit that, when set to 1, permits the alarm flag (AF) bit in Register C to assert IRQ . An alarm interrupt occurs for each second that the three time bytes equal the three alarm bytes, including a don’t-care alarm code of binary 11XXXXXX. The AF bit does not initiate the IRQ signal when the AIE bit is set to 0. The internal functions of the DS12R885 do not affect the AIE bit, but is cleared to 0 on RESET .Bit 4: Update-Ended Interrupt Enable (UIE). This bit is a read/write bit that enables the update-end flag (UF)bit in Register C to assert IRQ . The RESET pin going low or the SET bit going high clears the UIE bit. UIE is not modified by any internal DS12R885 functions, but is cleared to 0 on RESET .Bit 3: Square-Wave Enable (SQWE).When this bit is set to 1, a square-wave signal at the frequency set by the rate-selection bits RS3–RS0 is driven out on the SQW pin. When the SQWE bit is set to 0, the SQW pin is held low. SQWE is a read/write bit and is cleared by RESET . SQWE is low if disabled, and is high imped-ance when V CC is below V PF . SQWE is cleared to 0 on RESET .Bit 2: Data Mode (DM).This bit indicates whether time and calendar information is in binary or BCD format.The DM bit is set by the program to the appropriate for-mat and can be read as required. This bit is not modi-fied by internal functions or RESET . A 1 in DM signifies binary data, while a 0 in DM specifies BCD data.Bit 1: 24/12. The 24/12 control bit establishes the for-mat of the hours byte. A 1 indicates the 24-hour mode and a 0 indicates the 12-hour mode. This bit is read/write and is not affected by internal functions or RESET .Bit 0: Daylight Savings Enable (DSE).This bit is a read/write bit that enables two daylight savings adjust-ments when DSE is set to 1. On the first Sunday in April, the time increments from 1:59:59 AM to 3:00:00AM. On the last Sunday in October when the time first reaches 1:59:59 AM, it changes to 1:00:00 AM. When DSE is enabled, the internal logic tests for the first/last Sunday condition at midnight. If the DSE bit is not set when the test occurs, the daylight savings function does not operate correctly. These adjustments do not occur when the DSE bit is 0. This bit is not affected by internal functions or RESET .Control Register BD S 12R 885/D S 12C R 887/D S 12R 887Bit 7: Interrupt Request Flag (IRQF).This bit is set to 1 when any of the following are true:PF = PIE = 1AF = AIE = 1UF = UIE = 1Any time the IRQF bit is 1, the IRQ pin is driven low.This bit can be cleared by reading Register C or with a RESET .Bit 6: Periodic Interrupt Flag (PF).This bit is read-only and is set to 1 when an edge is detected on the selected tap of the divider chain. The RS3 through RS0bits establish the periodic rate. PF is set to 1 indepen-dent of the state of the PIE bit. When both PF and PIE are 1s, the IRQ signal is active and sets the IRQF bit.This bit can be cleared by reading Register C or with a RESET .Bit 5: Alarm Interrupt Flag (AF). A 1 in the AF bit indi-cates that the current time has matched the alarm time.If the AIE bit is also 1, the IRQ pin goes low and a 1appears in the IRQF bit. This bit can be cleared by reading Register C or with a RESET .Bit 5: Update-Ended Interrupt Flag (UF).This bit is set after each update cycle. When the UIE bit is set to 1, the 1 in UF causes the IRQF bit to be a 1, which asserts the IRQ pin. This bit can be cleared by reading Register C or with a RESET .Bits 3 to 0: Unused. These bits are unused in Register C. These bits always read 0 and cannot be written.Control Register Cthe condition of the battery connected to the V BACKUP pin. This bit is not writeable and should always be 1when read. If a 0 is ever present, an exhausted internal lithium energy source is indicated and both the con-tents of the RTC data and RAM data are questionable.This bit is unaffected by RESET .are not usable. They cannot be written and they always read 0.Nonvolatile RAM (NV RAM) The 114 general-purpose NV RAM bytes are not dedi-cated to any special function within the DS12R885. They can be used by the processor program as battery-backed memory and are fully available during the update cycle.Interrupts The DS12R885 includes three separate, fully automatic sources of interrupt for a processor. The alarm interrupt can be programmed to occur at rates from once per second to once per day. The periodic interrupt can be selected for rates from 500ms to 122µs. The update-ended interrupt can be used to indicate to the program that an update cycle is complete. Each of these inde-pendent interrupt conditions is described in greater detail in other sections of this text.The processor program can select which interrupts, if any, are to be used. Three bits in Register B enable the interrupts. Writing a logic 1 to an interrupt-enable bit permits that interrupt to be initiated when the event occurs. A 0 in an interrupt-enable bit prohibits the IRQ pin from being asserted from that interrupt condition. If an interrupt flag is already set when an interrupt is enabled, IRQ is immediately set at an active level, although the interrupt initiating the event may have occurred earlier. As a result, there are cases where the program should clear such earlier initiated interrupts before first enabling new interrupts.When an interrupt event occurs, the relating flag bit is set to logic 1 in Register C. These flag bits are set inde-pendent of the state of the corresponding enable bit in Register B. The flag bit can be used in a polling mode without enabling the corresponding enable bits. The interrupt flag bit is a status bit that software can interro-gate as necessary. When a flag is set, an indication is given to software that an interrupt event has occurred since the flag bit was last read; however, care should be taken when using the flag bits as they are cleared each time Register C is read. Double latching is includ-ed with Register C so that bits that are set remain sta-ble throughout the read cycle. All bits that are set (high) are cleared when read, and new interrupts that are pending during the read cycle are held until after the cycle is completed. One, two, or three bits can be set when reading Register C. Each used flag bit should be examined when Register C is read to ensure that no interrupts are lost.The second flag bit method is used with fully enabled interrupts. When an interrupt flag bit is set and the cor-responding interrupt-enable bit is also set, the IRQ pinis asserted low. IRQ is asserted as long as at least oneof the three interrupt sources has its flag and enablebits set. The IRQF bit in Register C is a 1 whenever theIRQ pin is driven low. Determination that the RTC initiat-ed an interrupt is accomplished by reading Register C.A logic 1 in bit 7 (IRQF bit) indicates that one or more interrupts have been initiated by the DS12R885. Theact of reading Register C clears all active flag bits andthe IRQF bit.Oscillator Control BitsWhen the DS12R887 and DS12CR887 are shippedfrom the factory, the internal oscillator is turned off. This feature prevents the lithium energy cell from beingused until it is installed in a system.A pattern of 010 in bits 4 to 6 of Register A turns the oscillator on and enables the countdown chain. A pat-tern of 11x (DV2 = 1, DV1 = 1, DV0 = X) turns the oscil-lator on, but holds the countdown chain of the oscillatorin reset. All other combinations of bits 4 to 6 keep the oscillator off.Square-Wave Output Selection Thirteen of the 15 divider taps are made available to a 1-of-16 multiplexer, as shown in the functional diagram.The square-wave and periodic-interrupt generatorsshare the output of the multiplexer. The RS0–RS3 bits in Register A establish the output frequency of the multi-plexer (see Table1). Once the frequency is selected, the output of the SQW pin can be turned on and off under program control with the square-wave enable bit, SQWE.Periodic Interrupt SelectionThe periodic interrupt causes the IRQ pin to go to anactive state from once every 500ms to once every122µs. This function is separate from the alarm inter-rupt, which can be output from once per second toonce per day. The periodic interrupt rate is selectedusing the same Register A bits that select the square-wave frequency (Table1). Changing the Register A bits affects the square-wave frequency and the periodic-interrupt output. However, each function has a separate enable bit in Register B. The SQWE bit controls the square-wave output. Similarly, the PIE bit in Register B enables the periodic interrupt. The periodic interruptcan be used with software counters to measure inputs, create output intervals, or await the next needed soft-ware function.DS12R885/DS12CR887/DS12R887D S 12R 885/D S 12C R 887/D S 12R 887Update CycleThe DS12R885 executes an update cycle once per second regardless of the SET bit in Register B. When the SET bit in Register B is set to 1, the user copy of the double-buffered time, calendar, and alarm bytes is frozen and does not update as the time increments.H owever, the time countdown chain continues to update the internal copy of the buffer. This featureallows time to maintain accuracy independent of read-ing or writing the time, calendar, and alarm buffers, and also guarantees that time and calendar information is consistent. The update cycle also compares each alarm byte with the corresponding time byte and issues an alarm if a match or if a don’t-care code is present in all three positions.There are three methods that can handle RTC access that avoid any possibility of accessing inconsistent time and calendar data. The first method uses the update-ended interrupt. If enabled, an interrupt occurs after every update cycle that indicates over 999ms is avail-able to read valid time and date information. If this interrupt is used, the IRQF bit in Register C should be cleared before leaving the interrupt routine.A second method uses the update-in-progress bit (UIP)in Register A to determine if the update cycle is in progress. The UIP bit pulses once per second. After the UIP bit goes high, the update transfer occurs 244µs later. If a low is read on the UIP bit, the user has at least 244µs before the time/calendar data is changed.Therefore, the user should avoid interrupt service rou-tines that would cause the time needed to read valid time/calendar data to exceed 244µs.The third method uses a periodic interrupt to determine if an update cycle is in progress. The UIP bit in Register A is set high between the setting of the PF bit in Register C (Figure 3). Periodic interrupts that occur at a rate greater than t BUC allow valid time and date infor-mation to be reached at each occurrence of the period-ic interrupt. The reads should be complete within 1(t PI/2+ t BUC ) to ensure that data is not read during the update cycle.Figure 3. UIP and Periodic Interrupt Timing。
