DS1312 Product details

Description

VCCI VCCO VBAT - +5V Power Supply Input - SRAM Power Supply Output - Backup Battery Input CEI - Chip Enable Input CEO TOL BW - Chip Enable Output - VCC Tolerance Select - Battery Warning Output (Open Drain) RST GND NC - Reset Output (Open Drain) - Ground - No Connection DESCRIPTION The DS1312 Nonvolatile Controller with Battery Monitor is a CMOS circuit which solves the application problem of converting CMOS RAM into nonvolatile memory.Incoming power is monitored for an outof-tolerance

Features

Converts CMOS SRAM into nonvolatile memory.
Unconditionally write-protects SRAM when VCC is out of tolerance.
Automatically switches to battery backup supply when VCC power failure occurs.
Monitors voltage of a lithium cell and provides advanced warning of impending battery failure.
Signals low-battery condition on active low Battery Warning output signal.
Optional 5% or 10% power-fail detection.
Space-saving 8-pin DIP and SOIC packages.
Optional 16-pin S.
