ATTINY13A-SS7

Microchip Tech · Pre-ordered MCUs · SOIC-8

ATTINY13A-SS7 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/RESET bidirectional Port B bit 5 (PCINT5/ADC0/dW) that is also the active-low reset input; a low level longer than the minimum pulse length generates a reset, and it can be used as a weak I/O pin if the reset function is disabled.
2 PB3 bidirectional Port B bit 3 bidirectional I/O with internal pull-up, with alternate functions PCINT3, CLKI (external clock input) and ADC3.
3 PB4 bidirectional Port B bit 4 bidirectional I/O with internal pull-up, with alternate functions PCINT4 and ADC2.
4 GND power_in Ground.
5 PB0 bidirectional Port B bit 0 bidirectional I/O with internal pull-up, with alternate functions MOSI, AIN0, OC0A and PCINT0.
6 PB1 bidirectional Port B bit 1 bidirectional I/O with internal pull-up, with alternate functions MISO, AIN1, OC0B, INT0 and PCINT1.
7 PB2 bidirectional Port B bit 2 bidirectional I/O with internal pull-up, with alternate functions SCK, ADC1, T0 and PCINT2.
8 VCC power_in Supply voltage, 1.8 - 5.5V operating range.
