DESCRIPTION
The DS1225Y 64k Nonvolatile SRAM is a 65,536-bit, fully static, nonvolatile RAM organized as 8192
words by 8 bits. Each NV SRAM 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
data corruption. The NV SRAM can be used in place of existing 8k x 8 SRAMs directly conforming to
the popular bytewide 28-pin DIP standard. The DS1225Y also matches the pinout of the 2764 EPROM or
the 2864 EEPROM, allowing direct substitution while enhancing performance. There is no limit on the
number of write cycles that can be executed and no additional support circuitry is required for micro-
processor interfacing.
