CY14B256Q Overview
CY14C256Q CY14B256Q CY14E256Q 256-Kbit (32 K × 8) SPI nvSRAM Not Remended for New Designs 256-Kbit (32 K × 8) SPI.
CY14B256Q Key Features
- 256-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 32 K × 8
- STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using SPI instruction
- 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 CY14X256Q1A)
- 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 cycle delay
