General Description
The MAX6900, I2C-bus-compatible real-time clock
(RTC) in a 6-pin TDFN package contains a real-time
clock/calendar and 31-byte 8-bit wide of static ran-
dom access memory (SRAM). The real-time clock/cal-
endar provides seconds, minutes, hours, day, date,
month, and year information. The end of the month date
is automatically 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 for-
mat with an AM/PM indicator.
