CY14B512J - 512-Kbit (64 K x 8) Serial (I2C) nvSRAM

General Description

Clock.

Runs at speeds up to a maximum of fSCL.

I/O.

Key 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 (except for CY14X512J1).
  • High reliability Infinite read, writ.
