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 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 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 temperature range, -40°C to +85°C.
The SOT23 package has been replaced by a TDFN. For addtional information click
