ATTINY13-20SSQ

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

ATTINY13-20SSQ 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 PB5 bidirectional Port B bit 5 also serves as the RESET input, where a low level longer than the minimum pulse length generates a reset, and can be used as a weak I/O pin.
2 PB3 bidirectional Port B bit 3 also serves as the CLKI clock input and ADC3 analog input.
3 PB4 bidirectional Port B bit 4 is a bi-directional I/O pin with selectable internal pull-up that also serves as ADC2 analog input.
4 GND power_in Ground.
5 PB0 (MOSI/AIN0/OC0A/PCINT0) bidirectional Port B bit 0 is a bi-directional I/O pin with selectable internal pull-up that also serves as MOSI, AIN0 and OC0A.
6 PB1 (MISO/AIN1/OC0B/INT0/PCINT1) bidirectional Port B bit 1 is a bi-directional I/O pin with selectable internal pull-up that also serves as MISO, AIN1, OC0B and external interrupt INT0.
7 PB2 (SCK/ADC1/T0/PCINT2) bidirectional Port B bit 2 is a bi-directional I/O pin with selectable internal pull-up that also serves as SCK, ADC1 and Timer/Counter0 clock input T0.
8 VCC power_in Digital supply voltage.
