CY14B256Q1 Description
CY14B256Q1 CY14B256Q2 CY14B256Q3 256-Kbit (32 K × 8) Serial (SPI) nvSRAM 256-Kbit (32 K × 8) Serial (SPI).
CY14B256Q1 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 user using HSB pin (Ha
- RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL)
- Automatic STORE on power-down with a small capacitor (except for CY14B256Q1) 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
