CY14C256Q CY14B256Q CY14E256Q
256-Kbit (32 K × 8) SPI nvSRAM
Not Remended for New Designs
256-Kbit (32 K × 8) SPI nvSRAM
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)
- High reliability
- Infinite read, write, and RECALL cycles
- 1million STORE cycles to QuantumTrap
