Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PB5 | bidirectional | Port B bit 5 (PCINT5/RESET/ADC0/dW): a low level longer than the minimum pulse length generates a reset, and the pin can also be used as a (weak) I/O pin. |
| 2 | PB3 | bidirectional | Port B bit 3 (PCINT3/CLKI/ADC3): bi-directional I/O with internal pull-up, with alternate functions external clock input CLKI, ADC3 and pin change interrupt PCINT3. |
| 3 | PB4 | bidirectional | Port B bit 4 (PCINT4/ADC2): bi-directional I/O with internal pull-up, with alternate functions ADC2 and pin change interrupt PCINT4. |
| 4 | GND | power_in | Ground. |
| 5 | PB0 | bidirectional | Port B bit 0 (MOSI/AIN0/OC0A/PCINT0): bi-directional I/O with internal pull-up, with alternate functions SPI MOSI, analog comparator input AIN0, timer output OC0A and PCINT0. |
| 6 | PB1 | bidirectional | Port B bit 1 (MISO/AIN1/OC0B/INT0/PCINT1): bi-directional I/O with internal pull-up, with alternate functions SPI MISO, analog comparator input AIN1, timer output OC0B, external interrupt INT0 and PCINT1. |
| 7 | PB2 | bidirectional | Port B bit 2 (SCK/ADC1/T0/PCINT2): bi-directional I/O with internal pull-up, with alternate functions SPI SCK, ADC1, timer clock input T0 and PCINT2. |
| 8 | VCC | power_in | Digital supply voltage, 2.7 - 5.5V for ATtiny13 (1.8 - 5.5V for ATtiny13V). |
