6 mA Serial real-time clock Datasheet - production data Description The M41T00S is a low-power serial real-time clock (RTC) with a built-in 32.
768 kHz oscillator (external crystal controlled).
Eight bytes of the SRAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.
Addresses and data are transferred serially via a two line, bidirectional I²C interface.
The built-in address register is incremented automatically after each WRITE or READ data byte.
The M41T00S has a built-in power sense circuit which detects power failures and automatically switches to the battery supply when a power failure occurs.
The energy needed to sustain the clock operations can be supplied by a small lithium button supply when a power failure occurs.
The eight clock address locations contain the century, year, month, date, day, hour, minute, and second in 24-hour BCD format.
Corrections for 28, 29 (leap year - valid until year 2100), 30 and 31 day months are made automatically.
The M41T00S is supplied in an 8-pin SOIC.
