General 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.
Key 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 applicati.
