1 Introduction
The Atmel UC3-A3 XPLAINED evaluation kit is a hardware platform to evaluate the
Atmel AT32UC3A3256 microcontroller.
The kit offers a large range of features that enables the Atmel AVR® UC3 user to
get started using UC3 peripherals right away and understand how to integrate the
UC3 device in their own design.

3 General information
The Atmel UC3-A3 XPLAINED kit is intended to demonstrate the Atmel
AT32UC3A3256 microcontroller. Figure 3-1 shows the available feature on the board.

3.1 Preprogrammed firmware
The Atmel AT32UC3A3256 on the Atmel UC3-A3 XPLAINED kit is preprogrammed
with a USB bootloader and a default firmware. The preprogrammed firmware in the
AT32UC3A3256 is a simple demonstration of the QTouch button and QTouch slider.
3.2 Power supply
The kit needs an external power supply that can deliver 5V and up to 500mA. The
actual current requirement for the board is much less than 500mA but in order to be
able to power possible expansion boards this margin is needed.
The power can be applied to the board either via the USB connector or on pin 10 on
the header J3. The USB connector is the preferred input because then it is possible to
connect expansion boards on top of the J3 header.
The 5V is regulated down to 3.3V with an on board LDO regulator, which provides
power to the entire board. Expansion top boards that require 5V will get this from the
header J3 pin 10.
3.3 Measuring the AT32UC3A3256 power consumption
As part of an evaluation of the AT32UC3A3256, it can be of interest to measure its
power consumption. The two-pin header with a jumper mounted on it is the only
3
32159A-AVR-01/11
connection between the common power plane VCC_P3V3 and the VCC_MCU_P3V3
power plane. By replacing the jumper with an amperemeter it is possible to determine
the current consumption of the Atmel AT32UC3A3256. To locate the power
measurement header, please refer to Figure 3-1.
WARNING
Do not power the board without having the jumper or an amperemeter
mounted. Otherwise, the device may be damaged.
3.4 Programming the kit
The kit can be programmed either from an external programming tool or through a
USB bootloader which is pre-programmed on the device.
The bootloader is evoked by pushing the push button (SW0) during power-on. I.e.
push button and then connect an USB cable to the kit. Programming can be
performed through the DFU target (bootloader programmer target) in the Atmel
AVR32 Studio.
How a programmer can be connected to the kit is described in Chapter 4.1.
4 Connectors
The Atmel UC3-A3 XPLAINED kit has five 10-pin, 100mil headers. Two headers have
a fixed communication interface (J1 and J4). One header has analog functionality
(J2), and the last header (J3) has general purpose digital I/O.
The 90° angled header is the JTAG programming and debugging header for the
AT32UC3A3256.
For the location of the respective headers, refer to Figure 3-1.
4.1 Programming header
The AT32UC3A3256 can be programmed and debugged by connecting an external
programming/debugging tool to the JTAG header. The header has a standard JTAG
programmer pinout (refer to online help in AVR32 Studio), and tools such as
JTAGICE mkII or AVR ONE! can thus be connected directly to the header.
NOTE
The grey female 10-pin header on JTAGICE mkII has to be used when connecting to
the kit. A scoring in the board is made to fit the orientation tab on the header.
NOTE
A standoff adapter (no. 1) is needed when using AVR ONE!.
NOTE
Pin 1 on the JTAG header is at the top right corner and is marked with a square pad.

4.2 I/O expansion headers
There are four available I/O expansion headers on the kit. Some pins have shared
functionality with onboard functionality. If “clean” expansion ports are needed, there
are available cut-straps on some of the ADC inputs to remove onboard functionality.
Table 4-2 to Table 4-5 show what is shared on the header pins.

5 Memories
The Atmel UC3-A3 XPLAINED has an external SDRAM memory mounted on the
board. There are also footprints available for adding either an industrial standard or a
proprietary Atmel DataFlash serial flash.
NOTE
The footprints share the same SPI lines including the chip select, and so it is not
possible to mount a device on both footprints at the same time.
Table 5-1. Compatible devices for the footprints.

6 Miscellaneous I/O
6.1 Mechanical button
The board is equipped with one mechanical button. Because the button is used to
enter bootloader mode it has a pull-up mounted, this means it is not necessary to use
the pull-up in the UC3 to detect the status of the button.
6.2 LEDs
The Atmel UC3-A3 XPLAINED has four yellow LEDs which are connected to the
Atmel AT32UC3A3256 and all of them are active low.
One dual LED is mounted near the USB connector. It has one green LED which is
used to indicate power and one red LED that can be used for other purposes. The
green LED will be active when power is applied to the board but it can be disabled by
software from the AT32UC3A3256 device if needed. The red LED is active low and
the green LED is active high.
6.3 Analog I/O
A RC filter and a NTC temperature sensor are connected to ADC0 and ADC1
respectively. These analog sensors are used as input to the ADC but it is also
possible to disconnect them by cutting the cut-straps on the bottom side of the board.
The RC filter (1. order low-pass) has an approximate 3dB cut-off frequency of 159Hz.
The input to the RC filter is one of the UC3 GPIO pins that can be configured to
output a PWM signal to the RC filter. This can be used to generate a DC voltage on
the output of the RC filter which can be measured on the ADC. As this is a 1. order
filter, the ripple on the DC voltage is proportional to the input frequency. A higher
input frequency will give lower ripple on the output.
6.4 Touch
The UC3-A3 XPLAINED kit has one QTouch button and one QTouch slider; both are
connected to GPIO pins on the AT32UC3A3256.
