CY14C256I CY14B256I, CY14E256I 2
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 I2C mand (Software STORE) or HSB pin (Hardware STORE)
- RECALL to SRAM initiated on power-up (Power-Up RECALL) or by I2C mand (Software RECALL)
- Automatic STORE on power-down with a small capacitor
- High reliability
- -
- -
Infinite read, write, and RECALL cycles 1 million STORE cycles to QuantumTrap
- Data retention:...
