ATTINY202-SSNR 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 voltage pin; the device operates from 1.8 V to 5.5 V (VDD operating supply voltage, Table 31-2). |
| 2 | PA6 | bidirectional | GPIO port A pin 6 with analog input AIN6 and AINN0, also carrying USART0 TxD, SPI0 MOSI (alternate position) and TCA0 WO0, and LUT0-OUT; alternate pin positions are selected through PORTMUX. |
| 3 | PA7 | bidirectional | GPIO port A pin 7 with analog input AIN7 and AINP0, also carrying USART0 RxD, SPI0 MISO (alternate position), TCA0 WO0 (alternate position) and LUT1-OUT; alternate pin positions are selected through PORTMUX. |
| 4 | PA1 | bidirectional | GPIO port A pin 1 with analog input AIN1, also carrying USART0 TxD (alternate position), SPI0 MOSI, TWI0 SDA, TCA0 WO1 and LUT0-IN1. |
| 5 | PA2 | bidirectional | GPIO port A pin 2 with analog input AIN2 and event output EVOUT0, also carrying USART0 RxD (alternate position), SPI0 MISO, TWI0 SCL, TCA0 WO2 and LUT0-IN2; this pin has full asynchronous external interrupt detection. |
| 6 | PA0 | bidirectional | GPIO port A pin 0 that doubles as the RESET/UPDI pin; RSTPINCFG fuse selects GPIO, UPDI or RESET, and 12 V on this pin can enable UPDI programming, with analog input AIN0, USART0 XDIR, SPI0 SS and LUT0-IN0 also available. |
| 7 | PA3 | bidirectional | GPIO port A pin 3 with analog input AIN3 and external clock input EXTCLK, also carrying USART0 XCK, SPI0 SCK, TCA0 WO0/WO3 and the CCL/USART OUT signal. |
| 8 | GND | power_in | Ground reference for the device. |
