ATTINY412-SSNR

Microchip Tech · Microcontrollers (MCU/MPU/SOC) · SOIC-8

ATTINY412-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 operating supply voltage is 2.7 V to 5.5 V (Table 36-2).
2 PA6 bidirectional General-purpose I/O pin PA6, multiplexed in Table 5-2 to AIN6, AINN0, OUT, TxD, MOSI, WO0, WOA and LUT0-OUT, and usable as an external interrupt and event input.
3 PA7 bidirectional General-purpose I/O pin PA7, multiplexed in Table 5-2 to AIN7, AINP0, RxD, MISO, WO0, WOB and LUT1-OUT, and usable as an external interrupt and event input.
4 PA1 bidirectional General-purpose I/O pin PA1, multiplexed in Table 5-2 to AIN1, TxD, MOSI, SDA, WO1 and LUT0-IN1, and usable as an external interrupt and event input.
5 PA2 bidirectional General-purpose I/O pin PA2, multiplexed in Table 5-2 to EVOUT0, AIN2, RxD, MISO, SCL, WO2 and LUT0-IN2; PA2 has full asynchronous pin-change detection.
6 PA0/RESET/UPDI bidirectional PA0 is multiplexed with AIN0, LUT0-IN0 and the RESET/UPDI function, which the RSTPINCFG fuse selects as GPIO, UPDI or RESET.
7 PA3/EXTCLK bidirectional General-purpose I/O pin PA3, multiplexed in Table 5-2 to EXTCLK, AIN3, OUT, XCK, SCK and WO0/WO3, and usable as an external clock input.
8 GND power_in Ground reference pin for the device.
