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.

SO8, 8-pin SOIC
