General Description

A, B, C CE CE0 - Address Inputs - Chip Enable Input - Chip Enable Outputs - Ground - + Battery 1 - + Battery 2 - Power Supply Tolerance - +5V Supply - RAM Supply - Power-fail - No Connection - CE7 GND VBAT1 VBAT2 TOL VCCI VCC0 PF NC DESCRIPTION The DS1211 Nonvolatile Controller x 8 Chip is a CMOS circuit which solves the application problem of converting CMOS RAMs into nonvolatile memories.

Incoming power is monitored for an out-oftolerance condition.

When such a condition is detected, the chip enables are inhibited to accomplish write protection and the battery is switched on to supply RAMs with uninterrupted power.

Key Features

  • Converts full CMOS RAMs into nonvolatile memories Unconditionally write protects when VCC is out of tolerance Automatically switches to battery when power-fail occurs 3 to 8 decoder provides control for up to eight CMOS RAMs Consumes less than 100 nA of battery current Tests battery condition on power-up Provides for redundant batteries Power-fail signal can be used to interrupt processor on power failure Optional 5% or 10% power-fail detection Optional 20-pin SOIC surface mount package Optional.
