Features
- -
512-Kbit nonvolatile static random access memory (nvSRAM)
- Internally organized as 64 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: 20...
