Section 1
Overview
1.1 Scope The AT91SAM7X-EK and the AT91SAM7XC-EK evaluation kits enable evaluation capa-
bilities and code development of applications running on the AT91SAM7X or the
AT91SAM7XC microcontroller.
This guide focuses on the AT91SAM7X-EK board as a common evaluation platform for
the AT91SAM7X and AT91SAM7XC devices in a 100-lead LQFP package.
1.2 Deliverables The package contains the following items:
! a board marked AT91SAM7X-EK
! one A/B-type USB cable
! one crossed serial RS232 cable
! one RJ45 crossed Ethernet cable
1.3 The AT91SAM7XEK Evaluation
Board
! universal input AC/DC power supply with US and EU plug adapter
! one DVD-ROM containing summary and full datasheets, datasheets with electrical
and mechanical characteristics, application notes and getting started documents for
all development boards and AT91 microcontrollers. An AT91 software package with C
and assembly listings is also provided. This allows the user to begin evaluating the
AT91 A R M
Depending on the model of the kit, the board is equipped with either an AT91SAM7X256
or an AT91SAM7XC256 (100-pin LQFP Green package) together with the following
interfaces:
! USB device port
! DBGU serial communication port
! RS232 serial communication port with RTS/CTS
! JTAG/ICE debug interface connector
! serial CAN communication ports
! MII Ethernet 100-base TX with auto MDIX capability
! buffered analog input and PWM output
®
Thumb® 32-bit microcontroller quickly.

Setting Up the AT91SAM7X-EK
Evaluation Board
2.1 Electrostatic Warning
The AT91SAM7X-EK evaluation board is shipped in a protective anti-static package.
The board must not be subjected to high electrostatic potentials. A grounding strap or
similar protective device should be worn when handling the board. Avoid touching the
component pins or any other metallic element.
2.2 Requirements In order to set up the AT91SAM7X-EK evaluation board, the following items are
required:
! the AT91SAM7X-EK evaluation board itself
! an A/B-type USB cable
or
! a DC USB power adapter (5V at 0.5 A) with USB A/B cable
Note: The kit is not delivered with a JTAG/ICE interface which is required to start eval-
uating the device.
