CY14B256LA-SP45XIT is a 256-Kbit (32 K × 8) parallel nvSRAM that combines fast SRAM with QuantumTrap nonvolatile storage. It runs from 2.7 V to 3.6 V and performs hands-off AutoStore to nonvolatile cells on power-down using a 61–180 µF VCAP capacitor, with RECALL on power-up or by software. The SP45 option supports 45 ns access, 1M STORE cycles, and 20-year data retention at -40 to 85°C.

Features

  • 32 K × 8 parallel SRAM interface
  • QuantumTrap nonvolatile per cell
  • AutoStore on power-down via VCAP
  • STORE via HSB pin control
  • STORE/RECALL via 6-read sequence
  • Parallel STORE/RECALL of all cells
  • 2.7 V to 3.6 V single-supply
  • 1,000 K nonvolatile STORE cycles
  • 20-year data retention
  • Infinite SRAM read/write cycles
  • Standby current max 5 mA
  • Input leakage ±1 µA (non-HSB)

Benefits

  • Keeps data on power loss automatically
  • No battery needed for data backup
  • Simple parallel bus like SRAM
  • Flexible STORE control options
  • Software-only backup/restore control
  • Fast recovery after power returns
  • Works from common 3 V rails
  • Long-lived logging of key data
  • Retains configuration for 20 years
  • Unlimited runtime SRAM updates
  • Cuts idle power in standby modes
  • Reduces leakage-sensitive designs
