    ATXMEGA128A4U-MH Typical application Circuitry


    The ATXMEGA128A4U-MH is a low-power, high-performance microcontroller from Microchip (previously Armed), featuring 128 KB of self-programmable flash memory, 8 KB of boot code section, and 8 KB SRAM. This 8-bit AVR RISC-based microcontroller comes with rich features. This guide will illustrate how to integrate the ATXMEGA128A4U-MH into your circuit:

    1. Power Supply:Connect the power supply to the VCC pin (pin 5) and ground to the GND pin (pin 6) of the ATXMEGA128A4U-MH. The typical operating voltage is between 1.6V to 3.6V. It is best to connect decoupling capacitors close to the power supply pins.

    2. Clock Source:The ATXMEGA128A4U-MH uses an internal factory-calibrated oscillator, so an external clock source is not necessary. However, if required, an external clock source can be connected to the XTAL1 (pin 4) and XTAL2 (pin 3) pins.

    3. Reset Mechanism:Connect a momentary push-button switch to the RESET pin (pin 1). When this button is pressed, the ATXMEGA128A4U-MH resets. Include a pull-up resistor between this pin and the VCC to prevent false triggering.

    4. PDI Programming Interface:The ATXMEGA128A4U-MH uses a 2-pin PDI (Program and Debug Interface) for programming. The PDI_ELK (pin 2) and PDI_DATA (pin 4) should be connected to your PDI programmer.

    5. Digital I/O Pins:ATXMEGA128A4U-MH features a host of digital I/O pins across various ports (Port A to Port R). These can be connected to peripheral devices like sensors, actuators, or communication modules as per your design.

    6. Analog Inputs:The ATXMEGA128A4U-MH comes with multiple ADC channels on various ports. You can connect analog sensors to these pins as needed in your design.

    7. Communication Interfaces:For communication, ATXMEGA128A4U-MH provides interfaces such as SART, SPI, and I2C. Connect these to your corresponding devices as needed. 8. USB Interface:The ATXMEGA128A4U-MH supports USB connectivity.

    Connect the D- (pin 22) and D+ (pin 23) pins to a USB connector via appropriate resistors as specified in the data sheet. Refer to the data sheet of ATXMEGA128A4U-MH for detailed information about all the features, pin assignments, and operational instructions. By following this guide and maintaining a good design practice, you can harness the full potential of the ATXMEGA128A4U-MH for your applications. Remember to consider the requirements of your application while planning your circuit, including the power needs, necessary peripherals, and the appropriate communication interfaces.
