ATTINY13-20PU

Microchip Tech · MICROCHIP · DIP-8

ATTINY13-20PU 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 used as RESET input: a low level longer than the minimum pulse length in Table 18-1 (page 115) generates a reset even without a running clock, and shorter pulses are not guaranteed to reset; the pin can also be used as a (weak) I/O pin.
2 PB3 bidirectional Port B bit 3 is a bidirectional I/O pin with optional internal pull-up that is tri-stated during reset, and it also serves as CLKI, ADC3 and PCINT3 alternate functions.
3 PB4 bidirectional Port B bit 4 is a bidirectional I/O pin with optional internal pull-up that is tri-stated during reset, and it also serves as ADC2 and PCINT4 alternate functions.
4 GND power_in Ground reference for the device.
5 PB0 (MOSI/AIN0/OC0A/PCINT0) bidirectional Port B bit 0 is a bidirectional I/O pin with symmetrical high sink and source drive and optional internal pull-up that is tri-stated during reset, and it also serves as MOSI, AIN0, OC0A and PCINT0 alternate functions.
6 PB1 (MISO/AIN1/OC0B/INT0/PCINT1) bidirectional Port B bit 1 is a bidirectional I/O pin with symmetrical high sink and source drive and optional internal pull-up that is tri-stated during reset, and it also serves as MISO, AIN1, OC0B, INT0 and PCINT1 alternate functions.
7 PB2 (SCK/ADC1/T0/PCINT2) bidirectional Port B bit 2 is a bidirectional I/O pin with symmetrical high sink and source drive and optional internal pull-up that is tri-stated during reset, and it also serves as SCK, ADC1, T0 and PCINT2 alternate functions.
8 VCC power_in Digital supply voltage; the ATtiny13 operating range is 2.7 - 5.5V, and 20 MHz operation requires 4.5 - 5.5V (ranges stated on page 1).
