ATTINY13A-PU

Microchip Tech · Microcontrollers (MCU/MPU/SOC) · DIP-8

ATTINY13A-PU from Microchip Tech, in a DIP-8. 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 internal pull-up; as RESET it generates a device reset on a low level longer than the minimum pulse length (shorter pulses are not guaranteed to reset), and it can be used as a weak I/O pin.
2 PB3 bidirectional Port B bit 3 is a bi-directional I/O pin with internal pull-up, also serving as the CLKI clock input and ADC3 analog input.
3 PB4 bidirectional Port B bit 4 is a bi-directional I/O pin with internal pull-up, also serving as ADC2 analog input.
4 GND power_in Ground reference for the device.
5 PB0 (MOSI/AIN0/OC0A/PCINT0) bidirectional Port B bit 0 is a bi-directional I/O pin with internal pull-up and high sink/source capability, also serving as MOSI, AIN0 and OC0A alternate functions; it is tri-stated when reset is active.
6 PB1 (MISO/AIN1/OC0B/INT0/PCINT1) bidirectional Port B bit 1 is a bi-directional I/O pin with internal pull-up and high sink/source capability, also serving as MISO, AIN1, OC0B and INT0 alternate functions; it is tri-stated when reset is active.
7 PB2 (SCK/ADC1/T0/PCINT2) bidirectional Port B bit 2 is a bi-directional I/O pin with internal pull-up and high sink/source capability, also serving as SCK, ADC1 and T0 alternate functions; it is tri-stated when reset is active.
8 VCC power_in Supply voltage; the datasheet gives the operating voltage range as 1.8 V to 5.5 V.
