DESCRIPTION
The DS1244 256k NV SRAM with a Phantom clock is a fully static nonvolatile RAM (NV SRAM)
(organized as 32k words by 8 bits) with a built-in real-time clock. The DS1244 has a self-contained
lithium energy source and control circuitry, which constantly monitors V
CC
for an out-of-tolerance
condition. When such a condition occurs, the lithium energy source is automatically switched on and
write protection is unconditionally enabled to prevent garbled data in both the memory and real-time
clock.
The phantom clock provides timekeeping information for hundredths of seconds, seconds, minutes, hours,
days, date, months, and years. The date at the end of the month is automatically adjusted for months with
fewer than 31 days, including correction for leap years. The phantom clock operates in either 24-hour or
12-hour format with an AM/PM indicator.
PACKAGES
The DS1244 is available in two packages: 28-pin DIP and 34-pin PowerCap module. The 28-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
DS1244P 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.
