Introduction

      
The MT-DB-X4 is a development board for the 44-pin Atmel AVR XMEGA AU, A, C, and D microcontrollers. The AU (ie: ATxmega128a4u) and C variants support USB device mode. All variants can be powered from USB or from the Vin pin. Two schottky diodes facilitate simple switching (and reverse-polarity protection) between the two power sources. This voltage is regulated to 3.3V by the onboard 500mA, low quiescent current LDO regulator that supports up to 6V DC input voltage. Overcurrent protection is provided by a 500mA PTC resettable fuse. Also mounted is a mini USB connector, green LED, 16MHz crystal, 32.768KHz RTC crystal, reset button, and a boot jumper. The board has 40 main dual inline header pins with 100 mil pin spacing and 700 mil row spacing which allows for mounting on a breadboard or perfboard. The PDI/SPI header can be used with an external programmer, or be reconfigured to be used as a SPI master or slave. A DFU bootloader comes preinstalled (except A or D variants) which allows programming of the chip over USB without an external programmer. The PCB measures approximately 2.1” x 0.9” x 0.062” (52mm x 33mm x 1.6mm).

Features

*    Atmel AVR XMEGA AU, A, C, or D 44-pin microcontroller
            ATxmega32a4u, ATxmega128a4u, ATxmega16C4, ATxmega32D4, ATxmega128D4
            AU (A4U) and C variants support USB device mode
*   Onboard 3.3V, 500mA LDO regulator
           up to 6V DC input
           low quiescent current (120uA typical, 220uA max.)
           low dropout (210mV typical, 350mV max. @ 500mA)
           0.5% output tolerance typical
           Over-current and over-temperature protection
*   Simple power source switching
           2 schottky diodes (Vbus and Vin)
           Reverse-polarity protection
           Vbus can be disconnected (solder jumper)
           Vin schottky can be shorted (solder jumper) to eliminate voltage drop (battery use)
           Either Vin or Vbus can be routed through a resistor divider (/2) to pin B3 (ADC)
*   PTC resettable fuse (500mA)
*   DFU bootloader preinstalled (FLIP for Windows or dfu-programmer for Linux)(NOT on A or D variants)
*   PDI/SPI header (PDI by default)
           As a PDI header, it is used to program the AVR with an external programmer
           Header can be converted to a SPI (master or slave) header
           Can mount the MT-SD MicroSD card slot directly to this header
*   16MHz crystal for main clock
*   32.768KHz crystal for real-time counter
*   Green Status LED (can be disconnected)
*   Reset button
*   Bootloader activation jumper
*   Mini USB connector
*   USB pins routed to header pins (for panel-mount USB connector)
*   Powered by USB or external power source (up to 6V) on Vin
*   Ferrite bead on analog supply
*   19 solder jumpers for configuration flexibility
*   All PORT pins routed to headers (except R0)
*   2 main headers are on 0.1” spacing (breadboard/perfboard mounting)
*   Two 3mm mounting holes (~5mm pad)
*   High-quality PCB with gold-plated finish
*   Measures approx. 2.1” x 0.9” (52mm x 33mm) and 0.062” (1.6mm) thick.

Drivers


    http://www.atmel.com/tools/flip.aspx

FLIP is a graphical utility for Windows used to load firmware into the XMEGA. FLIP supplies the USB DFU bootloader driver. Download FLIP 3.4.7 or higher from http://www.atmel.com/tools/flip.aspx and install. Older versions may not support the latest XMEGA variants (AU or C). Once FLIP is installed, the USB DFU drivers can be loaded. Install the boot jumper and power the board (or press reset). This will start the DFU bootloader. Windows will then prompt you for the driver, which is located in the Program Files/Atmel/Flip 3.4.7/usb directory. Point the installer to that directory and install.
