Real Time Clock Serial 56Byte 8-Pin TDFN T/R

The PT7C4311 serial real-time clock is a low-power clock/calendar with a programmable square-wave output. Address and data are transferred serially via a 2-wire bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in the 24- hour format indicator. Support I 2C-Bus (High speed mode 400kHz) Includes time (Hour/Minute/Second) and calendar (Century/Year/Month/Date/Day) counter functions Year 2000 compliant Automatic switch-over and deselect circuitry Time keeping voltage: 1.2V to 5.5V Software clock calibration 56 bytes of general purpose RAM Ultra-low battery supply current of 0.3µA Low operating current of 70µA Battery or super cap back-up Operating temperature: -40°C to 85°C Automatic leap year compensation Special software programmable output SOIC Package 8 Pin IC
