ATTINY84A-PU

Microchip Tech · MICROCHIP · DIP-14

ATTINY84A-PU from Microchip Tech, in a DIP-14. 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 VCC power_in Supply voltage (1.8-5.5V operating range).
2 PB0 bidirectional Port B bit 0, bi-directional I/O with selectable internal pull-up; alternate functions PCINT8/XTAL1/CLKI.
3 PB1 bidirectional Port B bit 1, bi-directional I/O with selectable internal pull-up; alternate functions PCINT9/XTAL2.
4 PB3 bidirectional Port B bit 3 / active-low RESET input (PCINT11/dW); a low level longer than the minimum pulse length generates a reset, and it is usable as a weak I/O pin when the RSTDISBL fuse is programmed.
5 PB2 bidirectional Port B bit 2, bi-directional I/O with selectable internal pull-up; alternate functions PCINT10/INT0/OC0A/CKOUT.
6 PA7 bidirectional Port A bit 7, bi-directional I/O with selectable internal pull-up; alternate functions PCINT7/ICP/OC0B/ADC7.
7 PA6 bidirectional Port A bit 6, bi-directional I/O with selectable internal pull-up; alternate functions PCINT6/OC1A/SDA/MOSI/DI/ADC6.
8 PA5 bidirectional Port A bit 5, bi-directional I/O with selectable internal pull-up; alternate functions ADC5/DO/MISO/OC1B/PCINT5.
9 PA4 bidirectional Port A bit 4, bi-directional I/O with selectable internal pull-up; alternate functions ADC4/USCK/SCL/T1/PCINT4.
10 PA3 bidirectional Port A bit 3, bi-directional I/O with selectable internal pull-up; alternate functions ADC3/T0/PCINT3.
11 PA2 bidirectional Port A bit 2, bi-directional I/O with selectable internal pull-up; alternate functions ADC2/AIN1/PCINT2.
12 PA1 bidirectional Port A bit 1, bi-directional I/O with selectable internal pull-up; alternate functions ADC1/AIN0/PCINT1.
13 PA0 bidirectional Port A bit 0, bi-directional I/O with selectable internal pull-up; alternate functions ADC0/AREF/PCINT0.
