AVR32DA28-I

Microchip Tech · Pre-ordered MCUs · SSOP-28-208mil

AVR32DA28-I from Microchip Tech, in a SSOP-28-208mil. 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 PA7 bidirectional General-purpose I/O pin PA7 with alternate functions CLKOUT and PTC X7/Y7, and it is the default position for ZCD1 OUT (alternate position PC7 selectable via PORTMUX).
2 PC0 bidirectional General-purpose I/O pin PC0 with alternate functions USART1 TxD and SPI1 MOSI.
3 PC1 bidirectional General-purpose I/O pin PC1 with alternate functions USART1 RxD and SPI1 MISO.
4 PC2 bidirectional General-purpose I/O pin PC2 with alternate functions TWI SDA (host), USART1 XCK and SPI1 SCK, and full asynchronous pin change sensing (Px2).
5 PC3 bidirectional General-purpose I/O pin PC3 with alternate functions TWI SCL (host), USART1 XDIR and SPI1 SS.
6 PD0 bidirectional General-purpose I/O pin PD0 that can be used as ADC0 analog input AIN0 (also PTC X16/Y16).
7 PD1 bidirectional General-purpose I/O pin PD1 that can be used as ADC0 analog input AIN1 and as zero-cross detector input ZCIN.
8 PD2 bidirectional General-purpose I/O pin PD2 that can be used as ADC0 analog input AIN2 and has full asynchronous pin change sensing (Px2).
9 PD3 bidirectional General-purpose I/O pin PD3 that can be used as ADC0 analog input AIN3 (also PTC X19/Y19).
10 PD4 bidirectional General-purpose I/O pin PD4 that can be used as ADC0 analog input AIN4 (also PTC X20/Y20).
11 PD5 bidirectional General-purpose I/O pin PD5 that can be used as ADC0 analog input AIN5 (also PTC X21/Y21).
12 PD6 bidirectional General-purpose I/O pin PD6 that can be used as ADC0 analog input AIN6 (also PTC X22/Y22) and has full asynchronous pin change sensing (Px6).
13 PD7 bidirectional General-purpose I/O pin PD7 that can be used as the external voltage reference input VREFA or ADC0 analog input AIN7.
14 AVDD power_in Analog supply pin; VDD and AVDD are internally connected on the AVR DA family (no separate power domains).
15 GND power_in Ground pin.
16 PF0 (XTAL32K1) bidirectional I/O pin PF0 that serves as the 32.768 kHz crystal connection XTAL32K1 and as positive-input-only ADC input AIN16.
17 PF1 (XTAL32K2) bidirectional I/O pin PF1 that serves as the 32.768 kHz crystal connection XTAL32K2 and as positive-input-only ADC input AIN17.
18 PF6 (RESET) input Input-only pin that works as the active-low external Reset when RSTPINCFG is set to RESET (otherwise a general input), and has an internal pull-up resistor.
19 UPDI bidirectional Dedicated Unified Program and Debug Interface pin for one-wire UART programming and debugging, with no other function.
20 VDD power_in Digital supply pin; all VDD pins are internally connected and must be at the same voltage, with 1.8 V to 5.5 V operating range per the ordering information.
21 GND power_in Ground pin.
22 PA0 (EXTCLK) bidirectional I/O pin PA0 that can serve as external clock input EXTCLK, with alternate functions USART0 TxD, TCA0 WO0 and PTC X0/Y0.
23 PA1 bidirectional General-purpose I/O pin PA1 with alternate functions USART0 RxD, TCA0 WO1 and PTC X1/Y1.
24 PA2 bidirectional General-purpose I/O pin PA2 with alternate functions TWI SDA (host), USART0 XCK, TCA0 WO2 and EVSYS EVOUTA, and full asynchronous pin change sensing (Px2).
25 PA3 bidirectional General-purpose I/O pin PA3 with alternate functions TWI SCL (host), USART0 XDIR and TCA0 WO3.
26 PA4 bidirectional General-purpose I/O pin PA4 with alternate functions SPI0 MOSI, USART0 TxD (alternate position) and TCA0 WO4.
27 PA5 bidirectional General-purpose I/O pin PA5 with alternate functions SPI0 MISO, USART0 RxD (alternate position) and TCA0 WO5.
28 PA6 bidirectional General-purpose I/O pin PA6 with alternate functions SPI0 SCK, USART0 XCK (alternate position) and full asynchronous pin change sensing (Px6).
