CY14MB256J - 256-Kbit (32 K × 8) Serial (I2C) nvSRAM

Download the CY14MB256J datasheet PDF. This datasheet also covers the CY14MC256J variant, as both devices belong to the same 256-kbit (32 k × 8) serial (i2c) nvsram family and are provided as variant models within a single manufacturer datasheet.

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 RECALL) to or SRAM initiated on power-up (Power-Up by I2C command (Software RECALL).
  • Automatic STORE on power-down with a small capacitor (except for CY14MX256J1).
  • High reliability.
  • Infinite re.
