ATTINY13A-MMU from Microchip Tech, in a DFN-10-EP(3x3). 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 and dW; a low level longer than the minimum pulse length on RESET generates a reset, and the pin can also be used as a (weak) I/O pin.
2 PB3 bidirectional Port B bit 3 bi-directional I/O with internal pull-up, alternate functions PCINT3, CLKI and ADC3.
3 DNC unconnected Do Not Connect.
4 PB4 bidirectional Port B bit 4 bi-directional I/O with internal pull-up, alternate functions PCINT4 and ADC2.
5 GND power_in Ground.
6 PB0 bidirectional Port B bit 0 bi-directional I/O with internal pull-up, alternate functions MOSI, AIN0, OC0A and PCINT0.
7 PB1 bidirectional Port B bit 1 bi-directional I/O with internal pull-up, alternate functions MISO, AIN1, OC0B, INT0 and PCINT1.
8 DNC unconnected Do Not Connect.
9 PB2 bidirectional Port B bit 2 bi-directional I/O with internal pull-up, alternate functions SCK, ADC1, T0 and PCINT2.
10 VCC power_in Supply voltage (operating range 1.8 to 5.5 V).
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
