■ Industry standard configurations  
❐ Industrial temperature  
❐ CY14B256Q1 has identical pin configuration to industry  
standard 8-pin NV memory  
Features  
■ 256-Kbit nonvolatile static random access memory (nvSRAM)  
❐ Internally organized as 32 K × 8  
❐ 8-pin dual flat no-lead (DFN) package and 16-pin small  
❐ STORE to QuantumTrap nonvolatile elements initiated

The  
Cypress  
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)  
❐ 40-MHz clock rate  
❐ Supports SPI mode 0 (0,0) and mode 3 (1,1)  
■ Write protection  
❐ Hardware protection using Write Protect (WP) pin  
❐ Software protection using Write Disable instruction  
❐ Software block protection for 1/4,1/2, or entire array  
Configuration  
■ Low power consumption
