Cypress (now Infineon)
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.
Key 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).
