M41T00M6F

STMicroelectronics · Real Time Clocks · SOIC-8

M41T00M6F from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OSCI input Oscillator input for the external 32.768 kHz crystal (12.5 pF load capacitance integrated).
2 OSCO output Oscillator output to the external 32.768 kHz crystal (RS max 60 kΩ, 12.5 pF load capacitance integrated).
3 VBAT power_in Battery supply voltage, 2.5 V min to 3.5 V max, used for backup when VCC falls below the switchover point VSO.
4 VSS power_in Ground.
5 SDA bidirectional Serial data address input/output of the I2C bus (100 kHz), requires an external pull-up resistor.
6 SCL input Serial clock input of the I2C bus, up to 100 kHz, requires an external pull-up resistor.
7 FT/OUT output Open-drain frequency test (512 Hz) or output driver reflecting the OUT control bit, requires an external pull-up resistor, up to 5.5 V.
8 VCC power_in Supply voltage, 2.0 to 5.5 V clock operating range.
