CY14B101KA-SP45XI

The CY14B101KA-SP45XI is a 1-Mbit nvSRAM (128K × 8) with integrated real-time clock, using QuantumTrap nonvolatile elements. It performs automatic STORE on power-down with an external 61 µF to 180 µF VCAP capacitor, and RECALL on power-up or by software/hardware. It operates from 2.7 V to 3.6 V over -40°C to 85°C, supports 45 ns access, and specifies 20-year data retention and 1 million STORE cycles.

Description

  • AutoStore saves data on power loss
  • Small cap avoids battery for store
  • HSB pin enables immediate save
  • SW cycles need no extra interface
  • Parallel xfer minimizes save time
  • SRAM-like speed for fast accesses
  • Restore state without wear limits
  • High STORE endurance for logging
  • Long retention reduces servicing
  • Keeps time/date during outages
  • Alarm/INT enables timed wakeups
  • Low backup current extends life
