Description

The Simtek STK12C68-M is a fast static RAM (40, 45 and 55ns), with a nonvolatile EEPROM 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 EEPROM. Data transfers from the SRAM to the EEPROM (the STORE operation) take place automatically upon power down using charge stored in an external 100 F capacitor. Transfers from the EEPROM to the SRAM (the RECALL operation) take place automatically on power up. Software sequences may also be used to initiate both STORE and RECALL operations. A STORE can also be initiated via a single pin.

The STK12C68-M is available in the following packages: a 28-pin 300 mil ceramic DIP and 28-pad LCC.
