CY14B256L - 256-Kbit (32K x 8) nvSRAM

Description

The Cypress CY14B256L is a fast static RAM with a nonvolatile element in each memory cell.

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

Features

  • 25 ns, 35 ns, and 45 ns access times.
  • “Hands-off” automatic STORE on power down with only a small capacitor.
  • STORE to QuantumTrap™ nonvolatile elements is 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.
  • 10 mA typical ICC at 200 ns cycle time.
  • 200,000 STORE cycles to QuantumTrap.
  • 20-year data retention @ 55°C.
