CY14E256I - 256-Kbit (32 K x 8) Serial (I2C) nvSRAM

Download the CY14E256I datasheet PDF. This datasheet also covers the CY14B256I variant, as both devices belong to the same 256-kbit (32 k x 8) serial (i2c) nvsram family and are provided as variant models within a single manufacturer datasheet.

Description

Clock: Runs at speeds

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 I2C command (Software STORE) or HSB pin (Hardware STORE).
  • RECALL to SRAM initiated on power-up (Power-Up RECALL) or by I2C command (Software RECALL).
  • Automatic STORE on power-down with a small capacitor.
  • High reliability.
  • Infinite read, write, and REC.
