ATTINY2313A-SU from Microchip Tech, in a SOIC-20-300mil. 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 | PA2 | input | Port A bit 2 with alternate functions RESET/dW/PCINT10; a low level longer than the minimum pulse length generates a reset unless the RSTDISBL fuse is programmed to use it as I/O. |
| 2 | PD0 | bidirectional | Port D bit 0 bi-directional I/O with internal pull-up, alternate functions RXD/PCINT11. |
| 3 | PD1 | bidirectional | Port D bit 1 bi-directional I/O with internal pull-up, alternate functions TXD/PCINT12. |
| 4 | PA1 | bidirectional | Port A bit 1 I/O with internal pull-up; alternate function XTAL2 is the output from the inverting oscillator amplifier (also PCINT9). |
| 5 | PA0 | bidirectional | Port A bit 0 I/O with internal pull-up; alternate function XTAL1 is the input to the inverting oscillator amplifier and internal clock circuit (also CLKI/PCINT8). |
| 6 | PD2 | bidirectional | Port D bit 2 bi-directional I/O with internal pull-up, alternate functions CKOUT/XCK/INT0/PCINT13. |
| 7 | PD3 | bidirectional | Port D bit 3 bi-directional I/O with internal pull-up, alternate functions INT1/PCINT14. |
| 8 | PD4 | bidirectional | Port D bit 4 bi-directional I/O with internal pull-up, alternate functions T0/PCINT15. |
| 9 | PD5 | bidirectional | Port D bit 5 bi-directional I/O with internal pull-up, alternate functions OC0B/T1/PCINT16. |
| 10 | GND | power_in | Ground. |
| 11 | PD6 | bidirectional | Port D bit 6 bi-directional I/O with internal pull-up, alternate functions ICPI/PCINT17. |
| 12 | PB0 | bidirectional | Port B bit 0 bi-directional I/O with internal pull-up, alternate functions AIN0/PCINT0. |
| 13 | PB1 | bidirectional | Port B bit 1 bi-directional I/O with internal pull-up, alternate functions AIN1/PCINT1. |
| 14 | PB2 | bidirectional | Port B bit 2 bi-directional I/O with internal pull-up, alternate functions OC0A/PCINT2. |
| 15 | PB3 | bidirectional | Port B bit 3 bi-directional I/O with internal pull-up, alternate functions OC1A/PCINT3. |
| 16 | PB4 | bidirectional | Port B bit 4 bi-directional I/O with internal pull-up, alternate functions OC1B/PCINT4. |
| 17 | PB5 | bidirectional | Port B bit 5 bi-directional I/O with internal pull-up, alternate functions MOSI/DI/SDA/PCINT5. |
| 18 | PB6 | bidirectional | Port B bit 6 bi-directional I/O with internal pull-up, alternate functions MISO/DO/PCINT6. |
| 19 | PB7 | bidirectional | Port B bit 7 bi-directional I/O with internal pull-up, alternate functions USCK/SCL/SCK/PCINT7. |
| 20 | VCC | power_in | Digital supply voltage, 1.8 - 5.5V operating range. |
