M40Z300W - NVRAM CONTROLLER for up to EIGHT LPSRAM

Datasheet Summary

Description

The M40Z300/W NVRAM Controller is a self-contained device which converts a standard low-power SRAM into a non-volatile memory.

A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition.

NOTE: 1.

For 16-pin SOIC package only.

Features

  • .5V or 4.5V to 5.5V) Symbol ILI (1) IC.
