Overview
M41T00 Features ■ For new designs use M41T00S ■ Counters for seconds, minutes, hours, day, month, years, and century ■ 32 kHz crystal oscillator integrating load capacitance (12.
5 pF) providing exceptional oscillator stability and high crystal series resistance operation ■ Serial interface supports I2C bus (100 kHz protocol) ■ Ultra low battery supply current of 0.
8 µA (typ at 3 V) ■ 2.
0 to 5.
5 V clock operating voltage ■ Automatic switchover and deselect circuitry (for 3 V application select M41T00S datasheet) ■ Software clock calibration to compensate crystal deviation due to temperature ■ Automatic leap year compensation ■ Operating temperature of -40 to 85 °C Serial real-time clock Not For New Design 8 1 SO8(M) Description The M41T00 is a low power serial real time clock with a built-in 32.
768 kHz oscillator (external crystal controlled).
Eight bytes of the RAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.
