STK12C68-M  
CMOS nvSRAM  
8K x 8 AutoStore™  
Nonvolatile Static RAM  
MIL-STD-883 / SMD # 5962-94599  
DESCRIPTION  
FEATURES  
The Simtek STK12C68-M is a fast static RAM (40, 45  
and 55ns), with a nonvolatile EEPROM element incor-  
porated in each static memory cell. The SRAM can be  
• 40, 45 and 55ns Access Times  
• 15 mA I at 200ns Access Speed  
CC  
• Automatic STORE to EEPROM on Power Down  
• Hardware or Software initiated STORE to  
EEPROM  
read and written an unlimited number of times, while  
independent nonvolatile data resides in EEPROM.  
Data transfers from the SRAM to the EEPROM (the  
STOREoperation)takeplaceautomaticallyuponpower  
down using charge stored in an external 100 µF  
capacitor. Transfers from the EEPROM to the SRAM  
(the RECALL operation) take place automatically on  
power up. Software sequences may also be used to  
• Automatic STORE Timing  
• 100,000 STORE cycles to EEPROM  
• 10 year data retention in EEPROM  
• Automatic RECALL on Power Up  
• Software initiated RECALL from EEPROM  
• Unlimited RECALL cycles from EEPROM  
• Single 5V±10% Operation  
initiate both STORE and RECALL operations.  
STORE can also be initiated via a single pin.  
A
The STK12C68-M is available in the following pack-  
ages: a 28-pin 300 mil ceramic DIP and 28-pad LCC.  
• Available in multiple standard packages
