Overview

DS1645Y/AB DS1645Y/AB Partitionable 1024K NV SRAM.

Key Features

  • 10 years minimum data retention in the absence of external power.
  • Data is automatically protected during power loss.
  • Directly replaces 128K x 8 volatile static RAM.
  • Write protects selected blocks of memory when pro- grammed.
  • Unlimited write cycles.
  • Low.
  • power CMOS.
  • Read and write access times as fast as 70 ns.
  • Lithium energy source is electrically disconnected to retain freshness until power is applied for the first.
