ATMEGA48V-10AU

Microchip Tech · ATMEL & AVR · TQFP-32(7x7)

ATMEGA48V-10AU from Microchip Tech, in a TQFP-32(7x7). 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 PD3 bidirectional Port D bit 3, a bi-directional I/O with internal pull-up, also usable as INT1, PCINT19, or OC2B.
2 PD4 bidirectional Port D bit 4, a bi-directional I/O with internal pull-up, also usable as PCINT20, T0, or XCK0.
3 GND power_in Ground reference for the digital supply.
4 VCC power_in Digital supply voltage, specified as 1.8 - 5.5V for ATmega48V.
5 GND power_in Ground reference for the digital supply.
6 VCC power_in Digital supply voltage, specified as 1.8 - 5.5V for ATmega48V.
7 PB6 bidirectional Port B bit 6 I/O with internal pull-up, used as XTAL1/TOSC1 input to the inverting oscillator amplifier depending on clock fuse settings.
8 PB7 bidirectional Port B bit 7 I/O with internal pull-up, used as XTAL2/TOSC2 output from the inverting oscillator amplifier depending on clock fuse settings.
9 PD5 bidirectional Port D bit 5 bi-directional I/O with internal pull-up, also usable as PCINT21, OC0B, or T1.
10 PD6 bidirectional Port D bit 6 bi-directional I/O with internal pull-up, also usable as PCINT22, AIN0, or OC0A.
11 PD7 bidirectional Port D bit 7 bi-directional I/O with internal pull-up, also usable as PCINT23 or AIN1.
12 PB0 bidirectional Port B bit 0 bi-directional I/O with internal pull-up, also usable as PCINT0, CLKO, or ICP1.
13 PB1 bidirectional Port B bit 1 bi-directional I/O with internal pull-up, also usable as PCINT1 or OC1A.
14 PB2 bidirectional Port B bit 2 bi-directional I/O with internal pull-up, also usable as PCINT2, OC1B, or SS0.
15 PB3 bidirectional Port B bit 3 bi-directional I/O with internal pull-up, also usable as PCINT3, OC2A, or MOSI0.
16 PB4 bidirectional Port B bit 4 bi-directional I/O with internal pull-up, also usable as PCINT4 or MISO0.
17 PB5 bidirectional Port B bit 5 bi-directional I/O with internal pull-up, also usable as PCINT5 or SCK0.
18 AVCC power_in Supply voltage pin for the A/D Converter, which must be connected to VCC even when the ADC is unused and via a low-pass filter when used.
19 ADC6 input Analog input channel 6 of the 10-bit A/D converter, powered from the analog supply (TQFP package only).
20 AREF input Analog reference pin for the A/D Converter.
21 GND power_in Ground reference for the digital supply.
22 ADC7 input Analog input channel 7 of the 10-bit A/D converter, powered from the analog supply (TQFP package only).
23 PC0 bidirectional Port C bit 0 bi-directional I/O with internal pull-up, also usable as ADC0 or PCINT8.
24 PC1 bidirectional Port C bit 1 bi-directional I/O with internal pull-up, also usable as ADC1 or PCINT9.
25 PC2 bidirectional Port C bit 2 bi-directional I/O with internal pull-up, also usable as ADC2 or PCINT10.
26 PC3 bidirectional Port C bit 3 bi-directional I/O with internal pull-up, also usable as ADC3 or PCINT11.
27 PC4 bidirectional Port C bit 4 bi-directional I/O with internal pull-up, also usable as ADC4, SDA0, or PCINT12.
28 PC5 bidirectional Port C bit 5 bi-directional I/O with internal pull-up, also usable as ADC5, SCL0, or PCINT13.
29 PC6/RESET input Reset input when the RSTDISBL fuse is unprogrammed; a low level longer than the minimum pulse length generates a Reset, otherwise it is an I/O pin with electrical characteristics differing from other Port C pins.
30 PD0 bidirectional Port D bit 0 bi-directional I/O with internal pull-up, also usable as RXD0 or PCINT16.
31 PD1 bidirectional Port D bit 1 bi-directional I/O with internal pull-up, also usable as TXD0 or PCINT17.
32 PD2 bidirectional Port D bit 2 bi-directional I/O with internal pull-up, also usable as INT0 or PCINT18.
