ATTINY26L-8SUR 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 | PB0 | bidirectional | Port B bit 0 I/O pin with optional internal pull-up, alternate functions MOSI/DI/SDA/OC1A. |
| 2 | PB1 | bidirectional | Port B bit 1 I/O pin with optional internal pull-up, alternate functions MISO/DO/OC1A. |
| 3 | PB2 | bidirectional | Port B bit 2 I/O pin with optional internal pull-up, alternate functions SCK/SCL/OC1B. |
| 4 | PB3 | bidirectional | Port B bit 3 I/O pin with optional internal pull-up, alternate function OC1B. |
| 5 | VCC | power_in | Digital supply voltage pin, 2.7V-5.5V for ATtiny26L. |
| 6 | GND | power_in | Digital ground pin. |
| 7 | PB4 | bidirectional | Port B bit 4 I/O pin with optional internal pull-up, alternate functions ADC7 and XTAL1 (input to inverting oscillator amplifier and internal clock circuit). |
| 8 | PB5 | bidirectional | Port B bit 5 I/O pin with optional internal pull-up, alternate functions ADC8 and XTAL2 (output from inverting oscillator amplifier). |
| 9 | PB6 | bidirectional | Port B bit 6 I/O pin with optional internal pull-up, alternate functions ADC9/INT0/T0. |
| 10 | PB7 | bidirectional | Port B bit 7, ADC10 or active-low RESET (pulses longer than 50 ns generate a reset); usable as I/O only when the RSTDISBL fuse is programmed. |
| 11 | PA7 | bidirectional | Port A bit 7 I/O pin with optional internal pull-up, alternate functions ADC6/AIN1. |
| 12 | PA6 | bidirectional | Port A bit 6 I/O pin with optional internal pull-up, alternate functions ADC5/AIN0. |
| 13 | PA5 | bidirectional | Port A bit 5 I/O pin with optional internal pull-up, alternate function ADC4. |
| 14 | PA4 | bidirectional | Port A bit 4 I/O pin with optional internal pull-up, alternate function ADC3. |
| 15 | AVCC | power_in | Supply voltage for Port A and the ADC; must be connected externally to VCC even if the ADC is unused, through a low-pass filter if the ADC is used. |
| 16 | GND | power_in | Ground pin (second GND pin on the package). |
| 17 | PA3 | bidirectional | Port A bit 3 I/O pin with optional internal pull-up, alternate function AREF. |
| 18 | PA2 | bidirectional | Port A bit 2 I/O pin with optional internal pull-up, alternate function ADC2. |
| 19 | PA1 | bidirectional | Port A bit 1 I/O pin with optional internal pull-up, alternate function ADC1. |
| 20 | PA0 | bidirectional | Port A bit 0 I/O pin with optional internal pull-up, alternate function ADC0. |
