DS1244, DS1244P 256k NV SRAM With Phantom Clock

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 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 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.
