STK11C88-3 32K x 8 nvSRAM 3.3V QuantumTrap CMOS Nonvolatile Static RAM ADVANCE FEATURES Operating VCC Range: 3.0V-3.6V 45ns and 55ns Access Times STORE to EEPROM Initiated by Software RECALL to SRAM Initiated by Software or Power Restore 8mA Typical ICC at 200ns Cycle Time Unlimited READ, WRITE and RECALL Cycles 1,000,000 STORE Cycles to EEPROM 100-Year Data Retention in EEPROM Commercial and Industrial Temperatures 28-Pin DIP and SOIC Packages DESCRIPTION The Simtek STK11C88-3 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 EEPROM. Data transfers from the SRAM to the EEPROM (the STORE operation), or from EEPROM to SRAM (the RECALL operation) take place using a software sequence. Transfers from the EEPROM to the SRAM (the RECALL operation) also take place automatically on restoration of power.
