DESCRIPTION
The DS1243Y 64K NV SRAM with Phantom Clock is a fully static nonvolatile RAM (organized as 8192
words by 8 bits) with a built-in real time clock. The DS1243Y has a self-contained lithium energy source
and control circuitry, which constantly monitors VCC 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 corrupted data in both the memory and real time clock. The Phantom
Clock provides timekeeping information including hundredths of seconds, seconds, minutes, hours, day,
date, month, and year information. 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.
