DS1314 3V Nonvolatile Controller

The DS1314 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 out-of-tolerance condition. When a condition is detected, chip enable is inhibited to accomplish write prot.

DS1314 Features

* z Converts CMOS SRAM into nonvolatile memory z Unconditionally write-protects SRAM when Vcc is out of tolerance z Automatically switches to battery backup supply when Vcc power failure occurs z Monitors voltage of a lithium cell and provides advanced warning of impending battery failure z Signals lo
