ATTINY25V-10MU

Microchip Tech · Pre-ordered MCUs · QFN-20-EP(4x4)

ATTINY25V-10MU from Microchip Tech, in a QFN-20-EP(4x4). 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, with alternate functions PCINT5/RESET/ADC0/dW; as RESET a low level longer than the minimum pulse length generates a reset, and it can also be used as a weak I/O pin.
2 PB3 bidirectional Port B bit 3 with internal pull-up, alternate functions PCINT3/XTAL1/CLKI/OC1B/ADC3.
3 DNC unconnected Do Not Connect.
4 DNC unconnected Do Not Connect.
5 PB4 bidirectional Port B bit 4 with internal pull-up, alternate functions PCINT4/XTAL2/CLKO/OC1B/ADC2.
6 DNC unconnected Do Not Connect.
7 DNC unconnected Do Not Connect.
8 GND power_in Ground.
9 DNC unconnected Do Not Connect.
10 DNC unconnected Do Not Connect.
11 PB0 bidirectional Port B bit 0 with internal pull-up, alternate functions MOSI/DI/SDA/AIN0/OC0A/OC1A/AREF/PCINT0.
12 PB1 bidirectional Port B bit 1 with internal pull-up, alternate functions MISO/DO/AIN1/OC0B/OC1A/PCINT1.
13 DNC unconnected Do Not Connect.
14 PB2 bidirectional Port B bit 2 with internal pull-up, alternate functions SCK/USCK/SCL/ADC1/T0/INT0/PCINT2.
15 VCC power_in Supply voltage.
16 DNC unconnected Do Not Connect.
17 DNC unconnected Do Not Connect.
18 DNC unconnected Do Not Connect.
19 DNC unconnected Do Not Connect.
20 DNC unconnected Do Not Connect.
21 EP power_in Exposed bottom pad, which should be soldered to ground.
