**Microchip Tech** · Microcontroller Units (MCUs/MPUs/SOCs) · SOIC-8

ATTINY212-SSN from Microchip Tech, 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 | VDD | power_in | Supply input; operating supply voltage is 2.7V to 5.5V per the general operating conditions. |
| 2 | PA6 | bidirectional | General purpose I/O pin PA6 with ADC inputs AIN6 and AINN0, DAC0 OUT output, and alternate USART0 TxD and SPI0 MOSI functions. |
| 3 | PA7 | bidirectional | General purpose I/O pin PA7 with ADC inputs AIN7 and AINP0, and alternate USART0 RxD and SPI0 MISO functions. |
| 4 | PA1 | bidirectional | General purpose I/O pin PA1 with ADC input AIN1, and alternate USART0 TxD, SPI0 MOSI and TWI0 SDA functions. |
| 5 | PA2 | bidirectional | General purpose I/O pin PA2 with ADC input AIN2, event output EVOUT0, and alternate USART0 RxD, SPI0 MISO and TWI0 SCL functions. |
| 6 | PA0 | bidirectional | General purpose I/O pin PA0 shared with RESET/UPDI, configurable via the RSTPINCFG fuse, with ADC input AIN0 and CCL input LUT0-IN0. |
| 7 | PA3 | bidirectional | General purpose I/O pin PA3 with external clock input EXTCLK, ADC input AIN3, and alternate USART0 XCK and SPI0 SCK functions. |
| 8 | GND | power_in | Ground reference for the device. |
