Features  
Functional Description  
35 ns access time  
The Cypress CY14V256LA is a fast static RAM, with a  
nonvolatile element in each memory cell. The memory is  
organized as 32 K bytes of 8 bits each. The embedded  
nonvolatile elements incorporate QuantumTrap technology,  
producing the world’s most reliable nonvolatile memory. The  
SRAM provides infinite 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. Both the STORE and RECALL  
operations are also available under software control.  
Internally organized as 32 K × 8  
Hands off automatic STORE on power down with only a small  
capacitor  
STORE to QuantumTrap nonvolatile elements initiated by  
software, device pin, or AutoStore on power down  
RECALL to SRAM initiated by software or power up  
Infinite read, write, and recall cycles  
1 million STORE cycles to QuantumTrap  
20 year data retention  
Core VCC = 3.0 V to 3.6 V; I/O VCCQ = 1.65 V to 1.95 V  
Industrial temperature  
48-ball fine-pitch ball grid array (FBGA) package  
Pb-free and restriction of hazardous substances (RoHS)
