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.

Figure 2-2. Functional overview of the Atmel UC3-A3 Xplained kit. 2.1 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. 2.2 Power supply The kit needs an external power supply that can deliver 5V and up to 500mA.
PAGE 5
2.4 Programming the kit The kit can be programmed either from an external programming tool or through a USB bootloader which is preprogrammed 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) with FLIP. How a programmer can be connected to the kit is described in Section 3.1. 3.

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. 5.3 Analog I/O A RC filter and a NTC temperature sensor are connected to ADC0 and ADC1 respectively.

7.1 Revision 10 Revision 10 of the UC3-A3 Xplained kit is the initially released version. This revision of the kit has the following product ID: A09-1053/10. 7.1.1 Known issues 7.1.1.1 Swapped TWI SCL and TWI SDA on header J4 The TWI lines that are connected to the pins one and two on the header J4 are swapped. Therefore the silkscreen on the board is not correct because TWI SCL function is on pin one instead of pin two and TWI SDA function is on pin two instead of pin one. 8.
