CY14ME064Q Datasheet 64-kbit (8 K X 8) Spi Nvsram

Manufacturer: Cypress (now Infineon)

Overview: CY14MB064Q CY14ME064Q 64-Kbit (8K × 8) SPI nvSRAM 64-Kbit (8K × 8) SPI.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

The Cypress CY14MX064Q combines 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.

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 (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 CY14MX064Q1A).
High reliability.
Infinite rea.
