ATTINY25V-10SU 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 is a bi-directional I/O pin with selectable internal pull-up that is tri-stated during reset; as the RESET input, a low level longer than the minimum pulse length generates a reset, while shorter pulses are not guaranteed to reset the device. |
| 2 | PB3 | bidirectional | Port B bit 3 is a bi-directional I/O pin with selectable internal pull-up that is tri-stated during reset, and on ATtiny25 it is exchanged with PB4 in ATtiny15 Compatibility Mode. |
| 3 | PB4 | bidirectional | Port B bit 4 is a bi-directional I/O pin with selectable internal pull-up that is tri-stated during reset, and on ATtiny25 it is exchanged with PB3 in ATtiny15 Compatibility Mode. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | PB0 (MOSI/DI/SDA/AIN0/OC0A/OC1A/AREF/PCINT0) | bidirectional | Port B bit 0 is a bi-directional I/O pin with symmetrical high sink and source drive, selectable internal pull-up, and tri-state during reset. |
| 6 | PB1 (MISO/DO/AIN1/OC0B/OC1A/PCINT1) | bidirectional | Port B bit 1 is a bi-directional I/O pin with symmetrical high sink and source drive, selectable internal pull-up, and tri-state during reset. |
| 7 | PB2 (SCK/USCK/SCL/ADC1/T0/INT0/PCINT2) | bidirectional | Port B bit 2 is a bi-directional I/O pin with symmetrical high sink and source drive, selectable internal pull-up, and tri-state during reset. |
| 8 | VCC | power_in | Supply voltage, specified as 1.8 to 5.5 V for the ATtiny25V. |
