ATMEGA32-16AUR

Microchip Tech · Pre-ordered MCUs · TQFP-44(10x10)

ATMEGA32-16AUR from Microchip Tech, in a TQFP-44(10x10). 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

3 PB7 bidirectional Port B bit 7, bidirectional I/O with selectable internal pull-up; alternate function SCK (SPI).
4 RESET input Active-low reset input; a low level longer than the minimum pulse length generates a reset even if the clock is not running.
5 VCC power_in Digital supply voltage (4.5V - 5.5V for ATmega32).
6 GND power_in Ground.
7 XTAL2 output Output from the inverting oscillator amplifier.
8 XTAL1 input Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
9 PD0 bidirectional Port D bit 0, bidirectional I/O with selectable internal pull-up; alternate function RXD (USART).
10 PD1 bidirectional Port D bit 1, bidirectional I/O with selectable internal pull-up; alternate function TXD (USART).
11 PD2 bidirectional Port D bit 2, bidirectional I/O with selectable internal pull-up; alternate function INT0.
12 PD3 bidirectional Port D bit 3, bidirectional I/O with selectable internal pull-up; alternate function INT1.
13 PD4 bidirectional Port D bit 4, bidirectional I/O with selectable internal pull-up; alternate function OC1B.
14 PD5 bidirectional Port D bit 5, bidirectional I/O with selectable internal pull-up; alternate function OC1A.
15 PD6 bidirectional Port D bit 6, bidirectional I/O with selectable internal pull-up; alternate function ICP1.
16 PD7 bidirectional Port D bit 7, bidirectional I/O with selectable internal pull-up; alternate function OC2.
17 VCC power_in Digital supply voltage (4.5V - 5.5V for ATmega32).
18 GND power_in Ground.
19 PC0 bidirectional Port C bit 0, bidirectional I/O with selectable internal pull-up; alternate function SCL (two-wire interface).
20 PC1 bidirectional Port C bit 1, bidirectional I/O with selectable internal pull-up; alternate function SDA (two-wire interface).
21 PC2 bidirectional Port C bit 2, bidirectional I/O; alternate function TCK (JTAG), pull-up stays active through reset when JTAG is enabled.
22 PC3 bidirectional Port C bit 3, bidirectional I/O; alternate function TMS (JTAG), pull-up stays active through reset when JTAG is enabled.
23 PC4 bidirectional Port C bit 4, bidirectional I/O; alternate function TDO (JTAG), tri-stated unless TAP states that shift out data are entered.
24 PC5 bidirectional Port C bit 5, bidirectional I/O; alternate function TDI (JTAG), pull-up stays active through reset when JTAG is enabled.
25 PC6 bidirectional Port C bit 6, bidirectional I/O with selectable internal pull-up; alternate function TOSC1 (timer oscillator).
26 PC7 bidirectional Port C bit 7, bidirectional I/O with selectable internal pull-up; alternate function TOSC2 (timer oscillator).
27 AVCC power_in Supply voltage pin for Port A and the A/D Converter; must be connected to VCC even if the ADC is not used, through a low-pass filter if the ADC is used.
