DS1218 - Nonvolatile Controller

Description

The DS1218 is a CMOS circuit which solves the application problems of converting CMOS RAM into nonvolatile memory.

Features

  • Converts CMOS RAM into nonvolatile memories.
  • Unconditionally write protects when VCC is out of tolerance.
  • Automatically switches to battery when power fail occurs.
  • Space saving 8-pin PDIP or 8-pin 150 mil SO Packages.
  • Consumes less than 100nA of battery current PIN.
