STK14C88  
32K x 8 AutoStore™ nvSRAM  
QuantumTrap™ CMOS  
Nonvolatile Static RAM  
FEATURES  
DESCRIPTION  
20ns, 25ns, 35ns and 45ns Access Times  
The Simtek STK14C88 is a fast static RAM with a  
• “Hands-offAutomatic STORE with External  
68µF Capacitor on Power Down  
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) can take place  
automatically on power down. A 68µF or larger  
capacitor tied from VCAP to ground guarantees the  
STORE operation, regardless of power-down slew  
rate or loss of power from “hot swapping”. Transfers  
from the EEPROM to the SRAM (the RECALL opera-  
tion) take place automatically on restoration of  
power. Initiation of STORE and RECALL cycles can  
also be software controlled by entering specific read  
sequences. A hardware STORE may be initiated with  
the HSB pin.  
STORE to EEPROM Initiated by Hardware,  
Software or AutoStoreon Power Down  
RECALL to SRAM Initiated by Software or  
Power Restore  
10mA 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  
Single 5V + 10% Operation  
Not Sensitive to Power On/Off Ramp Rates  
No Data Loss from Undershoot
