    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 out-
    of-tolerance condition. When such a condition is detected, chip enable is inhibited to accomplish write
    protection and the battery is switched on to supply the RAM with uninterrupted power. Special circuitry
    uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery
    consumption.
