CY14V101Q3
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) and mode 3 (1,1)
■ Write protection ❐ Hardware protection using Write Protect (WP) pin ❐ Software pro
