STK10C68  
CMOS nvSRAM  
High Performance  
8K x 8 Nonvolatile Static RAM  
FEATURES  
DESCRIPTION  
The Simtek STK10C68 is a fast static RAM (25, 30, 35,  
• 25, 30, 35 and 45ns Access Times  
• 12, 15, 20 and 25ns Output Enable Access  
• Unlimited Read and Write to SRAM  
• Hardware STORE Initiation  
and45ns),withanonvolatileelectrically-erasablePROM  
(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.  
• Automatic STORE Timing  
• 1,000,000 STORE cycles to EEPROM  
• 100 year data retention in EEPROM  
• Automatic RECALL on Power Up  
• Hardware RECALL Initiation  
• Unlimited RECALL cycles from EEPROM  
• Single 5V±10% Operation  
• Commercial and Industrial Temperatures  
The STK10C68 features industry standard pinout for  
nonvolatile RAMs in a 28-pin 300 mil plastic or ceramic  
DIP, and a 28-pin SOIC package. MIL-STD-883 and  
Standard Military Drawing (SMD #5962-93056) de-  
vices are also available.  
• Available in multiple standard packages
