CY14C512Q CY14B512Q CY14E512Q
512-Kbit (64K × 8) SPI nvSRAM
512-Kbit (64K × 8) SPI nvSRAM
Features
■ 512-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 64K × 8 ❐ STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using SPI instruction (Software STORE) or HSB pin (Hardware STORE) ❐ RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL) ❐ Support automatic STORE on power-down with a small capacitor (except for CY14X512Q1A)
■ High reliability
❐ Infinite read, write, and RECALL cycles ❐ 1million STORE cycles to QuantumTrap ❐ Data retention: 20 years at 85 C
■ 40-MHz, and 104-MHz High-speed serial peripheral interface (SPI) ❐ 40-MHz clock rate SPI write and read with zero cyc
