General Description

The Simtek STK25CA8 is a fast static RAM with a nonvolatile, electrically erasable PROM element incorporated in each static memory cell.

The SRAM can be read and written an unlimited number of times, while independent nonvolatile data resides in the EEPROM.

Data transfers from the SRAM to the EEPROM (the STORE operation) can take place automatically on power down using charge stored in system capacitance.

Key Features
