ATTINY4-TSHR

Microchip Tech · Microcontroller Units (MCUs/MPUs/SOCs) · SOT-23-6

ATTINY4-TSHR from Microchip Tech, in a SOT-23-6. 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, a bidirectional I/O pin with selectable internal pull-up and alternate functions PCINT0, TPIDATA, OC0A, ADC0 and AIN0.
2 GND power_in Ground.
3 PB1 bidirectional Port B bit 1, a bidirectional I/O pin with selectable internal pull-up and alternate functions PCINT1, TPICLK, CLKI, ICP0, OC0B, ADC1 and AIN1.
4 PB2 bidirectional Port B bit 2, a bidirectional I/O pin with selectable internal pull-up and alternate functions T0, CLKO, PCINT2, INT0 and ADC2.
5 VCC power_in Digital supply voltage, 1.8 - 5.5V operating range.
6 PB3 bidirectional Port B bit 3 with alternate functions PCINT3 and ADC3. It is also the active-low RESET input, where a low level longer than the minimum pulse length generates a reset, and it can be used as a weak I/O pin.
