STK11C48

2K x 8 nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• 20ns, 25ns, 35ns and 45ns Access Times

• STORE to EEPROM Initiated by Software

The Simtek STK11C48 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), 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.

• RECALL to SRAM Initiated by Software or

Power Restore

• 10mA Typical I_CCat 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 300 mil PDIP, 300 mil SOIC and

350 mil SOIC Packages
