M41T00
M41T00 is serial real time clock manufactured by STMicroelectronics.
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 pensate crystal deviation due to temperature
- Automatic leap year pensation
- Operating temperature of -40 to 85 °C
