STMicroelectronics · Real Time Clocks · SO-8
M41T11M6F from STMicroelectronics, in a SO-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, which has 12.5 pF load capacitance integrated in the device. |
| 2 | OSCO | output | Oscillator output for the external 32.768 kHz crystal (printed as OCSO in Table 1). |
| 3 | VBAT | power_in | Battery supply voltage, 2.5 V min, 3 V typ and 3.5 V max, 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 2-wire bus; requires a pull-up resistor to a positive supply. |
| 6 | SCL | input | Serial clock input of the 2-wire bus, up to 100 kHz; requires a pull-up resistor to a positive supply. |
| 7 | FT/OUT | output | Open-drain frequency test (512 Hz when FT bit set) or output driver reflecting the OUT bit; needs an external pull-up (max 5.5 V) and VOL is 0.4 V max at 3 mA. |
| 8 | VCC | power_in | Supply voltage, 2.0 to 5.5 V for clock operation; device deselects when VCC falls below VSO. |
