CY14B101KA-ZS45XI

CY14B101KA-ZS45XI is a 1 Mbit nvSRAM (128K × 8) with an integrated real-time clock, combining SRAM speed with nonvolatile QuantumTrap storage. It operates from 2.7 V to 3.6 V over –40°C to +85°C, supports 45 ns access, and performs hands-off AutoStore on power-down using a small capacitor on VCAP. STORE/RECALL can also be initiated by software or the HSB pin, with 20-year data retention.

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
