Cypress Semiconductor 1Mbit NVRAM, 8-Pin DFN, CY14B101Q2-LHXI

1-Mbit nonvolatile static random access memory (nvSRAM)
Internally organized as 128K ´ 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 (except for CY14B101Q1)
High reliability
Infinite read, write, and RECALL cycles
1 million STORE cycles to QuantumTrap
Data retention: 20 years
