FEATURES

PIN ASSIGNMENT

•

Real time clock keeps track of hundredths of

V_CC

A14/RST

seconds, minutes, hours, days, date of the

month, months, and years

A13

A12

•

32K x 8 NV SRAM directly replaces volatile

static RAM or EEPROM

Embedded lithium energy cell maintains

calendar operation and retains RAM data

=Watch function is transparent to RAM

operation

=Month and year determine the number of

days in each month; valid up to 2100

=Full 10% operating range

=Operating temperature range 0°C to 70°C

Over 10 years of data retention in the

absence of power
