FEATURES

PIN ASSIGNMENT

z Integrated NV SRAM, real time clock, crystal, power-fail

control circuit and lithium energy source

z Clock registers are accessed identical to the static RAM.

These registers are resident in the eight top RAM locations.

z Century byte register

z Totally nonvolatile with over 10 year of operation in the

absence of power

z BCD coded century, year, month, date, day, hours, minutes,

and seconds with automatic leap year compensation valid

up to the year 2100

z Battery voltage level indicator flag

z Power-fail write protection allows for ±10% Vcc power

supply tolerance

z Lithium energy source is electrically disconnected to retain

freshness until power is applied for the first time

z DIP Module only

Standard JEDEC bytewide 8k x 8 static RAM pinout

z PowerCap ^®Module Board only

Surface mountable package for direct connection to

PowerCap containing battery and crystal

Replaceable battery (PowerCap)

Power-On Reset Output
