**Shenzhen Fuman** · Microcontrollers (MCU/MPU/SOC) · SOT-23-6

XMC8P53S6 from Shenzhen Fuman, in a SOT-23-6. 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 | P61/SCL | bidirectional | General-purpose bidirectional I/O with programmable pull-up/pull-down (pull-down available on P60-P62) or open-drain output, forced to SCL in test mode, and a pin change can wake the MCU from sleep. |
| 2 | VSS | power_in | Negative power supply (ground) pin, the 0 V reference for VDD. |
| 3 | P62/TCC/CLK_OUT/CLK_TEST | bidirectional | General-purpose bidirectional I/O that can be reused as the external TCC input, as the internal RC clock output (divide-by-2), or as a clock test pin, with programmable pull-up/pull-down or open-drain and sleep wake-up on pin change. |
| 4 | P63/RESET_N/VPP | bidirectional | General-purpose bidirectional I/O that can be reused as an active-low external RESET_N pin (internal pull-up forced on) or as the OTP_VPP input in test mode, and is open-drain when configured as an output. |
| 5 | VDD | power_in | Positive power supply pin; recommended operating range is 2 V to 5 V, must not exceed the 5.5 V limit, and requires a 0.1 µF decoupling capacitor (a 100 Ω series resistor is required when operating above 4 V). |
| 6 | P60/INT/SDA | bidirectional | General-purpose bidirectional I/O that can be reused as the external interrupt INT (rising or falling edge selectable), forced to SDA in test mode, with programmable pull-up/pull-down or open-drain and sleep wake-up on pin change. |
