Note: The manufacturer provides a single datasheet file (CY14C256Q-CypressSemiconductor.pdf) that lists specifications for multiple related part numbers.
CY14C256Q CY14B256Q CY14E256Q
256-Kbit (32 K × 8) SPI nvSRAM Not Recommended for New Designs 256-Kbit (32 K × 8) SPI.
Key Features
256-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 32 K × 8.
STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using SPI instruction (Software STORE) or HSB pin (Hardware STORE).
RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL).
Support automatic STORE on power-down with a small capacitor (except for CY14X256Q1A).
