ATXMEGA128A3-AU Typical application Circuitry

ATXMEGA128A3-AU

The ATXMEGA128A3-AU is a high-performance, low-power 8/16-bit microcontroller. It uses the AVR enhanced RISC architecture, featuring a data bus of 8 bits and an address bus of 16 bits. We'll go into great depth about wiring the ATXMEGA128A3-AU into an electrical circuit in this article.To begin with, the ATXMEGA128A3-AU has a total of 100 pins, which provides plenty of room for versatile usage. In this scenario, we will focus on the basic connections required to get the microcontroller running.

1. Power Supply Connections: The VCC pins (pin 2 and pin 33) and ACC pin (pin 19) are the power supply input pins for the ATXMEGA128A3-AU. Connect a regulated 5V supply to these pins. The GND pins (pin 22 and pin 53) are connected to the ground of the power supply.

2. Oscillator Connections: For the internal RC oscillator, no external components are needed. However, if you prefer to use an external crystal oscillator for more accurate frequency, connect a crystal across pin 1 (XTAL1) and pin 21 (XTAL2). Then, connect two capacitors, usually 22pF, one side to each pin (XTAL1 and XTAL2), and the other side to the ground.

3. RESET pin: The RESET pin (pin 20) is active low and is used to reset the microcontroller. A typical way of connecting this is to use a pull-up resistor (10k Ohm) to the VCC, and a push button switch to the ground.

4. SPI Connections: The SPI interface is typically used for programming the ATXMEGA128A3-AU. Connect MOST (pin 91), MISS (pin 92), and SCK (pin 93) to the corresponding pins of the SPI programmer. SS (pin 90) is connected to the chip select of the programmer.

5. PART Connections: For PART communication, RXD0 (pin 38) and TXD0 (pin 37) are used. The TXD pin is for transmitting data, while RXD pin is for receiving data.

6. I/O Port Connections: The ATXMEGA128A3-AU provides various I/O ports (Port, Port, Port, Port, Port, Port, Port, North, Port, Port, Port, and Port) each consisting of eight pins (PX0 to PX7). These ports can be used as per the requirement of your specific application.

7. ADC Connections: If your application requires analog inputs, connect the desired analog voltage to one of the ADC (pins 9-16) or ADC (pins 25-32) pins.

Please ensure to follow the ATXMEGA128A3-AU data sheet for any specific requirements for your application. Additionally, it's crucial to use proper decoupling capacitors near the power supply pins to avoid any voltage fluctuations which may cause erratic behavior of the microcontroller.
