AVR128DA28-I

Microchip Tech · Pre-ordered MCUs · SOIC-28-300mil

AVR128DA28-I from Microchip Tech, in a SOIC-28-300mil. 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 PA7 bidirectional General-purpose I/O pin PA7 with alternate functions including CLKOUT clock output, USART0 XDIR, SPI0 SS, and TCD0 WOD.
2 PC0 bidirectional General-purpose I/O pin PC0 with alternate functions including USART1 TxD, SPI1 MOSI, TCA0 WO0 and CCL LUT1 input IN0.
3 PC1 bidirectional General-purpose I/O pin PC1 with alternate functions including USART1 RxD, SPI1 MISO, TCA0 WO1 and CCL LUT1 input IN1.
4 PC2 bidirectional General-purpose I/O pin PC2 with alternate functions including USART1 XCK, SPI1 SCK, master TWI SDA, and EVSYS output EVOUTC.
5 PC3 bidirectional General-purpose I/O pin PC3 with alternate functions including USART1 XDIR, SPI1 SS, master TWI SCL, and TCA0 WO3.
6 PD0 bidirectional General-purpose I/O pin PD0 that is also ADC0 analog input AIN0, with PTC X16/Y16 and an analog comparator negative input option.
7 PD1 bidirectional General-purpose I/O pin PD1 that is also ADC0 analog input AIN1, and can serve as the ZCD0 zero-cross input (ZCIN).
8 PD2 bidirectional General-purpose I/O pin PD2 that is also ADC0 analog input AIN2, with analog comparator positive input option and EVSYS output EVOUTD.
9 PD3 bidirectional General-purpose I/O pin PD3 that is also ADC0 analog input AIN3, with analog comparator input options and CCL LUT2 output.
10 PD4 bidirectional General-purpose I/O pin PD4 that is also ADC0 analog input AIN4, with analog comparator positive input option and PTC X20/Y20.
11 PD5 bidirectional General-purpose I/O pin PD5 that is also ADC0 analog input AIN5, with PTC X21/Y21 and analog comparator negative input option.
12 PD6 bidirectional General-purpose I/O pin PD6 that is also ADC0 analog input AIN6 and the DAC0 voltage output VOUT.
13 PD7 bidirectional General-purpose I/O pin PD7 that is also ADC0 analog input AIN7 and the external voltage reference input VREFA.
14 AVDD power_in Analog supply pin; AVDD and VDD are internally connected and there are no separate power domains on the AVR DA family.
15 GND power_in Ground pin, which must be connected to the same ground as the other GND pins.
16 PF0 (XTAL32K1) bidirectional General-purpose I/O pin PF0 that is also the 32 kHz crystal oscillator pin XTAL32K1 and ADC0 positive input-only AIN16.

18 PF6 (RESET) input Input-only pin PF6 that becomes the active-low external RESET input when the RSTPINCFG fuse selects RESET, otherwise it is a general input.
19 UPDI bidirectional Dedicated Unified Program and Debug Interface pin used for one-wire UART programming and debugging, with no other function.
20 VDD power_in Digital supply pin for 1.8-5.5 V operation; all VDD pins are internally connected and must be at the same voltage.
21 GND power_in Ground pin for the digital supply, which must be connected to the same ground as the other GND pins.
22 PA0 (EXTCLK) bidirectional General-purpose I/O pin PA0 that can serve as the external clock input EXTCLK, with alternate functions including USART0 TxD and TCA0 WO0.
23 PA1 bidirectional General-purpose I/O pin PA1 with alternate functions including USART0 RxD, TCA0 WO1, and CCL LUT0 input IN1.
24 PA2 bidirectional General-purpose I/O pin PA2 with alternate functions including USART0 XCK, master TWI SDA, TCA0 WO2, and EVSYS output EVOUTA.
25 PA3 bidirectional General-purpose I/O pin PA3 with alternate functions including USART0 XDIR, master TWI SCL, TCA1 WO3, and CCL LUT0 output.
