General Description
The MAX6901 3-wire serial interface real-time clock in a
TDFN package contains a real-time clock/calendar and
31 x 8 bits of static RAM (SRAM). The real-time
clock/calendar provides seconds, minutes, hours, day,
date, month, year, and century information. A
time/date-programmable polled ALARM is included in
the MAX6901. The end of the month date is automati-
cally adjusted for months with fewer than 31 days,
including corrections for leap year up to the year 2100.
The clock operates in either the 24hr or 12hr format
with an AM/PM indicator. A push-pull 32kHz output is
also included. The MAX6901 operates with a supply
voltage of +2V to +5.5V, is available in the ultra-small 8-
pin TDFN package, and works over the industrial tem-
perature range, -40°C to +85°C.
