STK20C04

CMOS nvSRAM

High Performance

512 x 8 Nonvolatile Static RAM

FEATURES

DESCRIPTION

The Simtek STK20C04 is a fast static RAM (30, 35,

45ns), with a nonvolatile electrically-erasable PROM

(EEPROM)elementincorporatedineachstaticmemory

cell. The SRAM can be read and written an unlimited

number of times, while independent nonvolatile data

resides in EEPROM. Data may easily be transferred

from the SRAM to the EEPROM (STORE), or from the

EEPROM to the SRAM (RECALL) using the NE pin. It

combines the high performance and ease of use of a

fast SRAM with nonvolatile data integrity.

• 30, 35 and 45ns Access Times

• 15, 20 and 25ns Output Enable Access

• Unlimited Read and Write to SRAM

• Hardware STORE Initiation

• Automatic STORE Timing

• 10 STORE cycles to EEPROM

• 10 year data retention in EEPROM

• Automatic RECALL on Power Up

• Hardware RECALL Initiation

• Unlimited RECALL cycles from EEPROM

• Single 5V±10% Operation

The STK20C04 features the industry standard pinout

for nonvolatile RAMs in a 28-pin 600 mil plastic DIP.

• Commercial and Industrial Temperatures

• Available in 600 mil PDIP package
