# ATTINY13A-SU

**Microchip Tech** · ATMEL & AVR · SOIC-8-208mil

ATTINY13A-SU from Microchip Tech, in a SOIC-8-208mil. 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 (PCINT5/ADC0/dW) that is also the reset input, where 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 pin is disabled. |
| 2 | PB3 | bidirectional | Port B bit 3 with internal pull-up, alternate functions PCINT3, CLKI and ADC3. |
| 3 | PB4 | bidirectional | Port B bit 4 with internal pull-up, alternate functions PCINT4 and ADC2. |
| 4 | GND | power_in | Ground. |
| 5 | PB0 | bidirectional | Port B bit 0 with internal pull-up, alternate functions MOSI, AIN0, OC0A and PCINT0. |
| 6 | PB1 | bidirectional | Port B bit 1 with internal pull-up, alternate functions MISO, AIN1, OC0B, INT0 and PCINT1. |
| 7 | PB2 | bidirectional | Port B bit 2 with internal pull-up, alternate functions SCK, ADC1, T0 and PCINT2. |
| 8 | VCC | power_in | Supply voltage, 1.8 to 5.5 V operating range. |
