ATTINY2313-20SU

Microchip Tech · MICROCHIP · SOIC-20-300mil

ATTINY2313-20SU from Microchip Tech, in a SOIC-20-300mil. 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 PA2 bidirectional Port A bit 2 with internal pull-up, alternate function active-low RESET input (a low level longer than the minimum pulse length generates a reset, even if the clock is not running) and debugWIRE (dW).
2 PD0 bidirectional Port D bit 0 with selectable internal pull-up, alternate function USART receive data (RXD); tri-stated during reset.
3 PD1 bidirectional Port D bit 1 with selectable internal pull-up, alternate function USART transmit data (TXD); tri-stated during reset.
4 PA1 bidirectional Port A bit 1 with internal pull-up, alternate function XTAL2, the output from the inverting oscillator amplifier.
5 PA0 bidirectional Port A bit 0 with internal pull-up, alternate function XTAL1, the input to the inverting oscillator amplifier and internal clock operating circuit.
6 PD2 bidirectional Port D bit 2 with selectable internal pull-up, alternate functions clock output (CKOUT), USART external clock (XCK) and external interrupt 0 (INT0).
7 PD3 bidirectional Port D bit 3 with selectable internal pull-up, alternate function external interrupt 1 (INT1).
8 PD4 bidirectional Port D bit 4 with selectable internal pull-up, alternate function Timer/Counter0 external clock input (T0).
9 PD5 bidirectional Port D bit 5 with selectable internal pull-up, alternate functions Timer/Counter0 compare output B (OC0B) and Timer/Counter1 clock input (T1).
10 GND power_in Ground.
11 PD6 bidirectional Port D bit 6 with selectable internal pull-up, alternate function Timer/Counter1 input capture (ICP).
12 PB0 bidirectional Port B bit 0 with selectable internal pull-up, alternate functions analog comparator positive input (AIN0) and pin change interrupt 0 (PCINT0).
13 PB1 bidirectional Port B bit 1 with selectable internal pull-up, alternate functions analog comparator negative input (AIN1) and pin change interrupt 1 (PCINT1).
14 PB2 bidirectional Port B bit 2 with selectable internal pull-up, alternate functions Timer/Counter0 compare output A (OC0A) and pin change interrupt 2 (PCINT2).
15 PB3 bidirectional Port B bit 3 with selectable internal pull-up, alternate functions Timer/Counter1 compare output A (OC1A) and pin change interrupt 3 (PCINT3).
16 PB4 bidirectional Port B bit 4 with selectable internal pull-up, alternate functions Timer/Counter1 compare output B (OC1B) and pin change interrupt 4 (PCINT4).
17 PB5 bidirectional Port B bit 5 with selectable internal pull-up, alternate functions SPI programming data input (MOSI), USI data input (DI), USI TWI data (SDA) and pin change interrupt 5 (PCINT5).
18 PB6 bidirectional Port B bit 6 with selectable internal pull-up, alternate functions SPI programming data output (MISO), USI data output (DO) and pin change interrupt 6 (PCINT6).
19 PB7 bidirectional Port B bit 7 with selectable internal pull-up, alternate functions USI clock (UCSK), USI TWI clock (SCL) and pin change interrupt 7 (PCINT7).
20 VCC power_in Digital supply voltage, 2.7 - 5.5V for the ATtiny2313 (20 MHz grade at 4.5 - 5.5V).
