RECALL to SRAM initiated on power-up (Power-Up  
RECALL) or by SPI instruction (Software RECALL)  
Functional Overview  
Support automatic STORE on power-down with a small  
capacitor (except for CY14X256Q1A)  
The Cypress CY14X256Q combines a 256-Kbit nvSRAM[1] with  
a nonvolatile element in each memory cell with serial SPI  
interface. The memory is organized as 32 K words of 8 bits each.  
The embedded nonvolatile elements incorporate the  
QuantumTrap technology, creating the world’s most reliable  
nonvolatile memory. The SRAM provides infinite read and write  
cycles, while the QuantumTrap cells provide highly reliable  
nonvolatile storage of data. Data transfers from SRAM to the  
nonvolatile elements (STORE operation) takes place automati-  
cally at power-down (except for CY14X256Q1A). On power-up,  
data is restored to the SRAM from the nonvolatile memory  
(RECALL operation). You can also initiate the STORE and  
RECALL operations through SPI instruction.  
High reliability  
Infinite read, write, and RECALL cycles
