CY14E512I - 512-Kbit (64 K x 8) Serial (I2C) nvSRAM

Download the CY14E512I datasheet PDF (CY14B512I included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 512-kbit (64 k x 8) serial (i2c) nvsram.

Features

  • 512-Kbit nonvolatile static random access memory (nvSRAM).
  • Internally organized as 64 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 RECALL cycl.
