Features  
Functional Description  
25 ns and 45 ns access times  
The Cypress STK22C48 is a fast static RAM with a nonvolatile  
element in each memory cell. The embedded nonvolatile  
Hands off automatic STORE on power down with external 68  
µF capacitor  
elements incorporate QuantumTrap technology producing the  
world’s most reliable nonvolatile memory. The SRAM provides  
unlimited read and write cycles, while independent nonvolatile  
data resides in the highly reliable QuantumTrap cell. Data  
transfers from the SRAM to the nonvolatile elements (the  
STORE operation) takes place automatically at power down. On  
power up, data is restored to the SRAM (the RECALL operation)  
from the nonvolatile memory. A hardware STORE is initiated with  
the HSB pin.  
STORE to QuantumTrap™ nonvolatile elements is initiated by  
software, hardware, or AutoStore™ on power down  
RECALL to SRAM initiated by software or power up  
Unlimited Read, Write, and Recall cycles  
1,000,000 STORE cycles to QuantumTrap  
100 year data retention to QuantumTrap  
Single 5V+10% operation  
Commercial and industrial temperatures  
28-pin 300 mil and (330 mil) SOIC package  
RoHS compliance
