CY14B256Q1/CY14B256Q2/CY14B256Q3  
Automatic STORE on power-down with a small capacitor  
(except for CY14B256Q1)  
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 cell provides highly reliable nonvolatile storage of  
data. Data transfers from SRAM to the nonvolatile elements  
(STORE operation) takes place automatically at power-down  
(except for CY14B256Q1). On power-up, data is restored to the  
SRAM from the nonvolatile memory (RECALL operation). The  
STORE and RECALL operations can also be initiated by the user  
through SPI instruction.  
High reliability  
Infinite read, write, and RECALL cycles  
1 million STORE cycles to QuantumTrap  
Data retention: 20 years  
High-speed serial peripheral interface (SPI)
