MCP2200T-I from Microchip Tech, in a SSOP-20-208mil. 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 | VDD | power_in | Positive supply pin for the device, with an operating voltage of 3.0V to 5.5V; the GPIO logic-high level follows the VDD voltage. |
| 2 | OSC1 | input | Oscillator input that must be driven by a 12 MHz clock (quartz crystal or ceramic resonator) with ±0.25% (2,500 ppm maximum) accuracy for the USB module. |
| 3 | OSC2 | output | Oscillator output for the 12 MHz quartz crystal or ceramic resonator circuit. |
| 4 | RST | input | External reset input that must be externally biased; holding it low generates a reset and the noise filter ignores small pulses, with a 1 kΩ to 10 kΩ resistor to VDD recommended for power-on reset. |
| 5 | GP7/TxLED | bidirectional | General purpose I/O pin 7, which can alternatively be configured as the USB transmit activity LED output (TxLED) for OUT messages. |
| 6 | GP6/RxLED | bidirectional | General purpose I/O pin 6, which can alternatively be configured as the USB receive activity LED output (RxLED) for IN messages. |
| 7 | GP5 | bidirectional | General purpose I/O pin 5, individually configurable as digital input or output. |
| 8 | GP4 | bidirectional | General purpose I/O pin 4, individually configurable as digital input or output. |
| 9 | GP3 | bidirectional | General purpose I/O pin 3, individually configurable as digital input or output. |
| 10 | Tx | output | USART TX data output of the UART interface. |
| 11 | RTS | output | Hardware flow control 'Request to Send' output signal of the UART interface. |
| 12 | Rx | input | USART RX data input of the UART interface. |
| 13 | CTS | input | Hardware flow control 'Clear to Send' input signal of the UART interface. |
| 14 | GP2 | bidirectional | General purpose I/O pin 2, individually configurable as digital input or output. |
| 15 | GP1/USBCFG | bidirectional | General purpose I/O pin 1, which can alternatively be configured as the USBCFG status output that starts low and goes high after the device configures on USB, and returns low in Suspend. |
| 16 | GP0/SSPND | bidirectional | General purpose I/O pin 0, which can alternatively be configured as the SSPND USB suspend status output that is active-low when Suspend is issued by the USB host. |
| 17 | VUSB | power_out | USB transceiver supply pin (internally connected to 3.3V from the internal LDO), which should be locally bypassed with a high-quality ceramic capacitor (0.22 µF to 0.47 µF recommended) and tied to a 3.3V rail in 3.3V self-powered designs. |
| 18 | D- | bidirectional | USB D- differential data line. |
| 19 | D+ | bidirectional | USB D+ differential data line. |
| 20 | VSS | power_in | Ground reference pin for the device. |
