CY14ME064Q Overview
The Cypress CY14MX064Q bines a 64 Kbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. The memory is organized as 8K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating the world’s most reliable nonvolatile memory.
CY14ME064Q Key Features
- 64-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 8K × 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 CY14MX064Q1A)
- High reliability
- Infinite read, write, and RECALL cycles
- 1million STORE cycles to QuantumTrap
- Data retention: 20 years at 85 C
- High speed serial peripheral interface (SPI)
- 40-MHz clock rate SPI write and read with zero cycle delay
