AVR364 3 General information This document targets the Atmel ATmega1284P evaluation kit revision 3, and parts of the document may, therefore, be inconsistent with earlier revisions of the product. For earlier revisions, please refer to the schematics, which is the only documentation available for these revisions. -

1.8V output and rerouting the power to the device (see schematic for an explanation). As some of the other ICs on the Atmel MEGA-1284P Xplained require 3.3V to operate correctly, these devices have to be removed. -
Page 6: Connectors
4 Connectors The Atmel MEGA-1284P 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... -

Please note that programming the Atmel AT32UC3B1256 using a programming tool will erase the boot loader. Please refer to the Atmel application note, AVR370: MEGA-1284P Xplained Getting Started Guide, for more details regarding how to program the onboard microcontrollers. 4.2 I/O expansion headers There are four available I/O expansion headers in the kit. - Page 8 Table 4-4.

Page 9: Memories
AVR364 5 Memories The Atmel MEGA-1284P Xplained kit does not have any external memories mounted on the board. Footprints are available for adding either an industrial standard flash device or an Atmel proprietary serial DataFlash device. The footprints share the same SPI lines, including the chip select, and it is, therefore, not possible to mount devices on both footprints at the same time. -

LED shine brighter when the button is pressed and the LED is turned on. When the LED is off, any button press will light up the LED. The Atmel MEGA-1284P Xplained also has one dual LED mounted near the USB connector. This is the power and status LED, which is connected to the board controller. -
