    ATXMEGA128A3U-AU Typical application Circuitry


    The ATXMEGA128A3U-AU is a high-performance, low-power 8/16-bit AVR microcontroller from Microchip Technology, featuring 128KB flash, 8KB SRAM, and 2KB EEPROM. A typical rule of thumb for wiring it into a circuit is as follows:

    1. Power Source:The ATXMEGA128A3U-AU runs on a 1.6 to 3.6 volt power range. The GND pin must be connected to ground, and the ACC and VCC pins must be connected to a power supply within this range.

    2.Connect a pushbutton that, when pressed, connects to ground to the RESET pin to reset the device. When the button is not pressed, the pin will remain high thanks to a pull-up resistor between RESET and VCC, and an extra capacitor may add a delay after reset.

    3. Oscillator:The ATXMEGA128A3U-AU supports both internal and external oscillators. If you're using an external oscillator, connect it to the XTAL1 and XTAL2 pins. If you're using the internal oscillator, ensure it's enabled in the firmware.

    4. Programming: The PDI (Program and Debug Interface) is supported by the ATXMEGA128A3U-AU. Connect the PDI_DATA (PDO) and PDI_ELK (PDI) pins to your programmer.

    5. Peripherals:The ATXMEGA128A3U-AU comes with a wide variety of peripherals, including but not limited to SART, SPI, I2C, and PWM. As required for your application, connect these to your peripherals.

    6. Decoupling Capacitors:Connect decoupling capacitors close to each VCC/ACC pin to the ground. They help in maintaining the power supply voltage level during transient changes and filter out noise.

    7. Voltage Regulator: If your power supply is higher than 3.6V, a voltage regulator is required to lower the voltage to a level that the ATXMEGA128A3U-AU can operate at.

    Based on the needs of your application, the aforementioned basic technique might not meet all of your individual needs.For further in-depth details, always refer to the data sheet or reference manual.
