Figure 2-2. Functional overview of the Atmel UC3-A3 Xplained kit. 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. -
Page 5: Programming The Kit
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 Atmel Studio), and tools such as JTAGICE3 or AVR ONE! can thus be connected directly to the header. - Page 6 PA30 GPIO2 PA29 GPIO3 PA28 GPIO4 PA27 GPIO5 PB00 GPIO6 PB11 GPIO7 PX19 VCC_P5V0 The VCC pin on this header has 5V and is connected to the USB power.
