DESCRIPTION
The DS1746 is a full function, year 2000 compliant (Y2KC), real-time clock/calendar (RTC) and 128k x
8 non-volatile static RAM. User access to all registers within the DS1746 is accomplished with a
bytewide interface as shown in Figure 1. The Real Time Clock (RTC) information and control bits reside
in the eight uppermost RAM locations. The RTC registers contain century, year, month, date, day, hours,
minutes, and seconds data in 24-hour BCD format. Corrections for the date of each month and leap year
are made automatically. The RTC clock registers are double buffered to avoid access of incorrect data
that can occur during clock update cycles. The double buffered system also prevents time loss as the
timekeeping countdown continues unabated by access to time register data. The DS1746 also contains its
own power-fail circuitry which deselects the device when the VCC supply is in an out of tolerance
condition. This feature prevents loss of data from unpredictable system operation brought on by low VCC
as errant access and update cycles are avoided.

PACKAGES
The DS1746 is available in two packages (32-pin DIP and 34-pin PowerCap module). The 32-pin DIP
style module integrates the crystal, lithium energy source, and silicon all in one package. The 34-pin
PowerCap Module Board is designed with contacts for connection to a separate PowerCap (DS9034PCX)
that contains the crystal and battery. This design allows the PowerCap to be mounted on top of the
DS1746P after the completion of the surface mount process. Mounting the PowerCap after the surface
mount process prevents damage to the crystal and battery due to the high temperatures required for solder
reflow. The PowerCap is keyed to prevent reverse insertion. The PowerCap Module Board and PowerCap
are ordered separately and shipped in separate containers. The part number for the PowerCap is
DS9034PCX.
CLOCK OPERATIONS-READING THE CLOCK
While the double buffered register structure reduces the chance of reading incorrect data, internal updates
to the DS1746 clock registers should be halted before clock data is read to prevent reading of data in
transition. However, halting the internal clock register updating process does not affect clock accuracy.
Updating is halted when a one is written into the read bit, bit 6 of the century register, see Table 2. As
long as a one remains in that position, updating is halted. After a halt is issued, the registers reflect the
count, that is day, date, and time that was current at the moment the halt command was issued. However,
the internal clock registers of the double buffered system continue to update so that the clock accuracy is
not affected by the access of data. All of the DS1746 registers are updated simultaneously after the
internal clock register updating process has been re-enabled. Updating is within a second after the read bit
is written to zero.

SETTING THE CLOCK
As shown in Table 2, bit 7 of the century register is the write bit. Setting the write bit to a one, like the
read bit, halts updates to the DS1746 registers. The user can then load them with the correct day, date and
time data in 24 hour BCD format. Resetting the write bit to a zero then transfers those values to the actual
clock counters and allows normal operation to resume.
STOPPING AND STARTING THE CLOCK OSCILLATOR
The clock oscillator may be stopped at any time. To increase the shelf life, the oscillator can be turned off
to minimize current drain from the battery. The OSC bit is the MSB (bit 7) of the seconds registers, see
Table 2. Setting it to a one stops the oscillator.
FREQUENCY TEST BIT
As shown in Table 2, bit 6 of the day byte is the frequency test bit. When the frequency test bit is set to
logic “1” and the oscillator is running, the LSB of the seconds register will toggle at 512 Hz. When the
seconds register is being read, the DQ0 line will toggle at the 512 Hz frequency as long as conditions for
access remain valid (i.e., CE low, OE low, WE high, and address for seconds register remain valid and
stable).
CLOCK ACCURACY (DIP MODULE)
The DS1746 is guaranteed to keep time accuracy to within ±1 minute per month at 25°C. The clock is
calibrated at the factory by Dallas Semiconductor using special calibration nonvolatile tuning elements.
The DS1746 does not require additional calibration and temperature deviations will have a negligible
effect in most applications. For this reason, methods of field clock calibration are not available and not
necessary.
CLOCK ACCURACY (POWERCAP MODULE)
The DS1746P and DS9034PCX are each individually tested for accuracy. Once mounted together, the
module is guaranteed to keep time accuracy to within ±1.53 minutes per month (35 ppm) at 25°C.

RETRIEVING DATA FROM RAM OR CLOCK
The DS1746 is in the read mode whenever OE (output enable) is low, WE (write enable) is high, and CE
(chip enable) is low. The device architecture allows ripple-through access to any of the address locations
in the NV SRAM. Valid data will be available at the DQ pins within tAA after the last address input is
stable, providing that the CE and OE access times and states are satisfied. If CE or OE access times and
states are not met, valid data will be available at the latter of chip enable access (tCEA ) or at output enable
access time (tOEA ). The state of the data input/output pins (DQ) is controlled by CE and OE. If the outputs
are activated before tAA , the data lines are driven to an intermediate state until tAA . If the address inputs
are changed while CE and OE remain valid, output data will remain valid for output data hold time (tOH
but will then go indeterminate until the next address access.
)
WRITING DATA TO RAM OR CLOCK
The DS1746 is in the write mode whenever WE, and CE are in their active state. The start of a write is
referenced to the latter occurring transition of WE, or CE. The addresses must be held valid throughout
the cycle. CE or WE must return inactive for a minimum of t WR prior to the initiation of another read or
write cycle. Data in must be valid t DS prior to the end of write and remain valid for tDH afterward. In a
typical application, the OE signal will be high during a write cycle. However, OE can be active provided
that care is taken with the data bus to avoid bus contention. If OE is low prior to WE transitioning low the
data bus can become active with read data defined by the address inputs. A low transition on WE will
then disable the outputs tWEZ after WE goes active.

DS1746/DS1746P
DATA RETENTION MODE
The 5 volt device is fully accessible and data can be written or read only when VCC is greater than VPF
.
However, when VCC is below the power fail point, VPF , (point at which write protection occurs) the
internal clock registers and SRAM are blocked from any access. At this time the power fail reset output
signal (RST) is driven active and will remain active until VCC returns to nominal levels. When VCC falls
below the battery switch point VSO (battery supply level), device power is switched from the VCC pin to the
backup battery. RTC operation and SRAM data are maintained from the battery until VCC is returned to
nominal levels. The 3.3 volt device is fully accessible and data can be written or read only when VCC is
greater than VPF . When VCC falls below the power fail point, VPF , access to the device is inhibited. At this
time the power fail reset output signal (RST) is driven active and will remain active until VCC returns to
nominal levels. If VPF is less than VBAT , the device power is switched from VCC to the backup supply (VBAT
)
when VCC drops below VPF . If VPF is greater than VBAT , the device power is switched from VCC to the
backup supply (VBAT ) when VCC drops below VBAT . RTC operation and SRAM data are maintained
from the battery until VCC is returned to nominal levels. The RST signal is an open drain output and
requires a pull up. Except for the RST, all control, data, and address signals must be powered down when
VCC is powered down.
BATTERY LONGEVITY
The DS1746 has a lithium power source that is designed to provide energy for clock activity, and clock
and RAM data retention when the VCC supply is not present. The capability of this internal power supply
is sufficient to power the DS1746 continuously for the life of the equipment in which it is installed. For
specification purposes, the life expectancy is 10 years at 25°C with the internal clock oscillator running in
the absence of VCC power. Each DS1746 is shipped from Dallas Semiconductor with its lithium energy
source disconnected, guaranteeing full energy capacity. When VCC is first applied at a level greater than
VPF , the lithium energy source is enabled for battery backup operation. Actual life expectancy of the
DS1746 will be much longer than 10 years since no lithium battery energy is consumed when VCC is
present.
BATTERY MONITOR
The DS1746 constantly monitors the battery voltage of the internal battery. The Battery Flag bit (bit 7) of
the day register is used to indicate the voltage level range of the battery. This bit is not writable and
should always be a one when read. If a zero is ever present, an exhausted lithium energy source is
indicated and both the contents of the RTC and RAM are questionable.

.
6. Each DS1746 has a built–in switch that disconnects the lithium source until V CC is first applied by
the user. The expected t DR is defined for DIP modules and assembled PowerCap modules as a
cumulative time in the absence of V CC starting from the time power is first applied by the user.
7. Real–Time Clock Modules (DIP) can be successfully processed through conventional wave–
soldering tecniques as long as temperatures as long as temperature exposure to the lithium energy
source contained within does not exceed +85°C. Post solder cleaning with water washing
techniques is acceptable, provided that ultra-sonic vibration is not used.
In addition, for the PowerCap:
a. Dallas Semiconductor recommends that PowerCap Module bases experience one pass through
solder reflow oriented with the label side up (“live – bug”).
b. Hand Soldering and touch–up: Do not touch or apply the soldering iron to leads for more than 3
(three) seconds. To solder, apply flux to the pad, heat the lead frame pad and apply solder.
To remove the part, apply flux, heat the lead frame pad until the solder reflows and use a
solder wick to remove solder.
8. t AH1 , t DH1 are measured from WE going high.
9. t AH2 , t DH2 are measured from CE going high.

NOTE:
Dallas Semiconductor recommends that PowerCap Module bases experience one pass through solder
reflow oriented with the label side up (“live – bug”).
Hand Soldering and touch–up: Do not touch or apply the soldering iron to leads for more than 3 (three)
seconds. To solder, apply flux to the pad, heat the lead frame pad and apply solder. To remove the part,
apply flux, heat the lead frame pad until the solder reflows and use a solder wick to remove solder.
