Datasheet Summary
1 Mbit (128 K × 8) Serial SPI nvSRAM
Features
- 1-Mbit nonvolatile static random access memory (nvSRAM)
- Internally organized as 128 K × 8
- STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by user using HSB pin (Hardware STORE) or SPI instruction (Software STORE)
- 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
- High reliability
- Infinite read, write, and RECALL cycles
- 1 million STORE cycles to QuantumTrap
- Data retention: 20 years
- High speed serial peripheral interface (SPI)
- 30 MHz clock rate
- Supports SPI mode 0 (0,0)...
