ATXMEGA256A3BU-AU Typical application Circuitry

ATXMEGA256A3BU-AU

The ATXMEGA256A3BU-AU is a high-performance, low-power microcontroller from Microchip's AVR MEGA series. Here's a rudimentary guide on connecting this MCU in your circuit:

1. Power Supply: Connect VCC (Pins 6, 58 on the 64-pin TQFP package) to a 1.6-3.6V power supply. Connect GND (Pins 5, 57 on the 64-pin TQFP package) to your system ground. Place a 100nF decoupling capacitor close to each of these pins.

2. Reset: Connect the RESET/PDI_CLK pin (Pin 48 on the 64-pin TQFP package) to a pull-up resistor to VCC. This pin can also be used for programming and debugging the ATXMEGA256A3BU-AU via PDI (Program and Debug Interface).

3. Crystal Oscillator: Connect a crystal oscillator to XTAL1 (Pin 60 on the 64-pin TQFP package) and XTAL2 (Pin 61 on the 64-pin TQFP package) to provide a clock for the microcontroller.

4. I/O Ports: The ATXMEGA256A3BU-AU has multiple I/O ports (Port A to Port R). For instance, Port A pins (PA0-PA7) are Pins 34-41 on the 64-pin TQFP package. Connect these as required by your application, ensuring each pin's electrical characteristics are adhered to.

5. PART: The ATXMEGA256A3BU-AU provides several PART modules for serial communication. For instance, to use UARTC0, connect a device's RX line to TXD0 (Pin 13 on the 64-pin TQFP package) and its TX line to RXD0 (Pin 14 on the 64-pin TQFP package).

6. Programming: For programming the MCU, use the PDI_DATA (Pin 47 on the 64-pin TQFP package) and PDI_ELK (Pin 48 on the 64-pin TQFP package) pins.

This is a simple guide, and the actual connections might vary based on your specific application. Always refer to the ATXMEGA256A3BU-AU data sheet and follow recommended PCB layout and design practices. The ATXMEGA256A3BU-AU provides advanced features like multiple SART, SPI, and I2C interfaces, ADC's, Days, and timers, making it a versatile choice for a wide range of applications.
