CY14U256LA-BA35XI is a 256-Kbit (32 K × 8) parallel nvSRAM combining SRAM with QuantumTrap nonvolatile storage. It performs automatic STORE on power-down using a 120–180 µF VCAP capacitor and RECALL on power-up, with hardware or software STORE/RECALL support. The device runs from 2.7–3.6 V core and 1.65–1.95 V I/O, offers 35 ns access, 20-year retention, and 1M STORE cycles in a 48-ball FBGA for –40 to 85°C.

Features

  • 32K × 8 fast SRAM + nonvolatile
  • 35 ns SRAM access time
  • AutoStore on power-down (VCAP)
  • VCAP capacitor 120–180 µF
  • STORE via AutoStore, pin, software
  • RECALL on power-up or software
  • HSB open-drain busy indicator
  • Write/STORE inhibit at low VCC
  • I/O disabled when VCCQ too low
  • VCC 2.7–3.6 V supply
  • VCCQ 1.65–1.95 V I/O supply
  • 20-year retention, 1,000K STORE

Benefits

  • Keeps data through power loss
  • 35 ns SRAM cuts wait states
  • AutoStore needs no firmware action
  • VCAP enables simple power-fail save
  • Pin or SW STORE fits many designs
  • Fast restore on every power-up
  • HSB busy flag avoids collisions
  • Low-VCC inhibit prevents corruption
  • I/O-off blocks brownout writes
  • Core supply supports 3.3 V rails
  • Low-voltage I/O matches MPUs
  • Long life for frequent data saves
