    FEATURES
    Integrated NV SRAM, Real-Time Clock,
    Crystal, Power-Fail Control Circuit, and
    Lithium Energy Source
    Clock Registers are Accessed Identically to
    the Static RAM. These Registers are Resident
    in the Eight Top RAM Locations.
    Century Byte Register (i.e., Y2K Compliant)
    Totally Nonvolatile with Over 10 Years of
    Operation in the Absence of Power
    BCD-Coded Century, Year, Month, Date,
    Day, Hours, Minutes, and Seconds with
    Automatic Leap-Year Compensation Valid
    Up to the Year 2100
    Battery Voltage-Level Indicator Flag
    Power-Fail Write Protection Allows for ±10%
    VCC Power-Supply Tolerance
    Lithium Energy Source is Electrically
    Disconnected to Retain Freshness Until
    Power is Applied for the First Time
    DIP Module Only
    Standard JEDEC Byte-Wide 32k x 8 Static
    RAM Pinout
