CY14U256LA Datasheet 256-Kbit (32K x 8) nvSRAM

Manufacturer: Cypress (now Infineon)

Datasheet Details

The Cypress CY14U256LA is a fast static RAM, with a nonvolatile element in each memory cell.

The memory is organized as 32 K bytes of 8 bits each.

The embedded nonvolatile elements incorporate QuantumTrap technology, producing the world’s most reliable nonvolatile memory.
