CY14E256LA - 256-Kbit nvSRAM

General Description

The Cypress CY14E256LA is a fast static RAM, with a nonvolatile element in each memory cell.

The memory is organized as 32 KB.

Key Features

  • 25 ns and 45 ns access times.
  • Internally organized as 32 K × 8 (CY14E256LA).
  • Hands-off automatic STORE on power-down with only a small capacitor.
  • STORE to QuantumTrap nonvolatile elements initiated by software, device pin, or autostore on power-down.
  • RECALL to SRAM initiated by software or power-up.
  • Infinite read, write, and RECALL cycles.
  • 1 million STORE cycles to QuantumTrap.
  • 20-year data retention.
  • Single 5 V + 10% operation.
  • Industrial tempe.
