    Overview

    The Atmel AVR XMEGA-A3BU Xplained evaluation kit (ATXMEGAA3BU-XPLD) is a hardware platform to evaluate the Atmel ATxmega256A3BU microcontroller. The XMEGA-A3BU Xplained contain one QTouch button sensor, three mechanical buttons, two LEDs, 3 analog sensors, a USB port, battery backup system and a 128x32 pixel FSTN LCD display. The AVR Xplained expansion headers provide easy access to analog and digital I/O pins. The board is powered by the USB cable and equipped with the standard 10-pin JTAG header that connects to the full range of AVR debuggers.

    The kit offers a large range of features that enables the Atmel AVR XMEGA® user to get started using XMEGA peripherals right away and understand how to integrate the XMEGA device in their own design. The ATxmega256A3BU on the XMEGA-A3BU Xplained is pre-programmed with a boot loader and a default firmware. The kit needs an external power supply that can deliver 5V and up to 500mA. The Atmel AVR XMEGA-A3BU Xplained kit has five 10-pins, 100mil headers. One header is used for programming the Atmel AVR ATxmega256A3BU, and the others are used to access spare analog and digital pins on the Atmel AVR XMEGA (expansion headers).

    The Atmel® AVR® XMEGA®-A3BU Xplained evaluation kit demo software is created to showcase the XMEGA-A3BU, touch button and LCD, using a simple menu navigation system, and small applications showcasing different features. The XMEGA-A3BU Xplained board features a monochrome LCD (liquid crystal display), which is a bundle containing an LCD controller (ST7565R) and an LCD panel (C12832_A1Z), with white backlight.

    The LCD controller offers two different interfacing modes:

    • Parallel interface mode in which display data is written by the master MCU (XMEGA for this board) to the controller memory, eight bits at a time using eight data lines for the transfer.
    • Serial interface mode where the master MCU produces a clock and a serial data signal, generally known as SPI (Serial Peripheral Interface).

    Warning: Do not power the board without having the jumper or an amperemeter mounted since this can cause latch-up of the Atmel AVR ATxmega256A3BU due to current flow into the I/O pins.

    NOTE: The XMEGA-A3BU Xplained can be used to evaluate the XMEGA A1/A3/A4 and A1U/A3U/A4U devices. The devices shares the same peripherals, but the A1, A3 and A4 devices has different pin count and hence different number of each peripherals. The A3BU devices features Battery Back-up for the RTC peripheral, which the other devices does not. The XMEGA A1 devices features an External Bus Interface (EBI) which the A3BU devices does not. To evaluate the EBI it is recommended to use the XMEGA-A1 Xplained.
