## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input; the VDD voltage sets the logic-high level of the GPIO and SPI pins, and the device operates from 3.3V to 5.5V. |
| 2 | OSC1 | input | Oscillator input that must be a 12 MHz clock with accuracy of ±0.25% (2,500 ppm maximum) to provide the USB full-speed frequency. |
| 3 | OSC2 | output | Oscillator output for the 12 MHz quartz crystal or ceramic resonator connection. |
| 4 | RST | input | Reset input where holding the pin low generates an external reset, with a noise filter that ignores small pulses; a 1 kΩ to 10 kΩ pull-up to VDD enables the on-chip POR. |
| 5 | GP0 | bidirectional | General purpose I/O 0 that can alternately be configured as Chip Select CS0. |
| 6 | GP1 | bidirectional | General purpose I/O 1 that can alternately be configured as Chip Select CS1, and is the default Chip Select line at power-up. |
| 7 | GP2 | bidirectional | General purpose I/O 2 that can alternately be configured as Chip Select CS2 or as the USB Suspend (SSPND) output, which is active low when USB Suspend is issued by the host. |
| 8 | GP3 | bidirectional | General purpose I/O 3 that can alternately be configured as Chip Select CS3 or as the SPI traffic LED output, driven low during an SPI transfer. |
| 9 | MOSI | output | SPI master data output. |
| 10 | GP4 | bidirectional | General purpose I/O 4 that can alternately be configured as Chip Select CS4, USB Low Power indicator (LOWPWR), or external interrupt input. |
| 11 | SCK | output | SPI master clock output. |
| 12 | GP5 | bidirectional | General purpose I/O 5 that can alternately be configured as Chip Select CS5 or as the USBCFG output, which starts high and goes low once the device is configured on USB. |
| 13 | MISO | input | SPI master data input. |
| 14 | GP6 | bidirectional | General purpose I/O 6 that can alternately be configured as Chip Select CS6 or as the external interrupt input. |
| 15 | GP7 | bidirectional | General purpose I/O 7 that can alternately be configured as Chip Select CS7 or as the SPI bus release acknowledge output. |
| 16 | GP8 | bidirectional | General purpose I/O 8 that can alternately be configured as Chip Select CS8 or as the SPI bus release request input, which is active when driven low. |
| 17 | VUSB | power_out | Output of the internal 3.3V USB transceiver regulator that requires a locally connected ceramic bypass capacitor, recommended between 0.22 µF and 0.47 µF. |
| 18 | D- | bidirectional | Full-speed USB 2.0 differential data minus line. |
| 19 | D+ | bidirectional | Full-speed USB 2.0 differential data plus line. |
| 20 | VSS | power_in | Ground reference for the device. |
