CY14B256KA-SP25XI is a 256-Kbit (32 K × 8) parallel nvSRAM with integrated real time clock, using QuantumTrap nonvolatile elements. It runs from a 2.7 V to 3.6 V supply over −40°C to 85°C and offers 25 ns access. Data is automatically STOREd on power-down with a 61 µF to 180 µF VCAP capacitor and can be software- or HSB-pin initiated, with RECALL on power-up, supporting 20-year retention and 1,000 K STORE cycles.

Features

  • 256-Kbit (32 K × 8) nvSRAM
  • AutoStore on power-down
  • STORE via SW or HSB pin
  • RECALL on power-up or SW
  • 1,000 K STORE cycle endurance
  • 20-year data retention
  • 25 ns and 45 ns access options
  • 2.7 V to 3.6 V single-supply
  • RTC with alarm and watchdog
  • RTC backup current 0.35 µA typ
  • RTC osc start time 1–2 s
  • 61 µF min VCAP for AutoStore

Benefits

  • Keeps SRAM data after power loss
  • No code needed for save on drop
  • Choose HW or SW save control
  • Quick restore on next power-up
  • Supports frequent data logging
  • Reduces service due to 20-year hold
  • SRAM-like speed for fast access
  • Single 3 V rail cuts power complexity
  • Maintains time when main is off
  • 0.35 µA typ extends backup life
  • Alarm enables timed wake and events
  • VCAP enables hands-off power fail save
