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