The AT91SAM7X-EK and AT91SAM7XC-EK evaluation kits enable evaluation capabilities and code development.
The AT91SAM7X‑EK evaluation board is a common platform for evaluating AT91SAM7X and AT91SAM7XC microcontrollers in a 100‑lead LQFP package. The kit includes the board, USB, RS232 and Ethernet cables, a universal AC/DC power supply, and a DVD‑ROM with documentation and software.
The guide covers safety warnings, required equipment, power‑up procedures, board layout, configuration straps, schematics, and revision history. Detailed descriptions of the board’s interfaces—USB device, DBGU serial, RS232, JTAG/ICE, CAN, Ethernet, analog inputs and PWM outputs—are provided along with connector pin‑outs and expansion options.
| Supported microcontrollers | AT91SAM7X256 or AT91SAM7XC256 (100‑pin LQFP) |
|---|---|
| USB interface | USB device port |
| Serial interface | DBGU serial communication port |
| RS232 interface | RS232 serial communication port with RTS/CTS |
| Debug interface | JTAG/ICE debug interface connector |
| CAN interface | Serial CAN communication ports |
| Ethernet interface | MII Ethernet 100‑base TX with auto MDIX |
| Analog/PWM I/O | Buffered analog input and PWM output |
The board can be equipped with either an AT91SAM7X256 or an AT91SAM7XC256 microcontroller in a 100‑pin LQFP package.
The kit includes an A/B‑type USB cable, a crossed serial RS232 cable, and a crossed RJ45 Ethernet cable.
It provides an MII Ethernet 100‑base TX interface with auto‑MDIX capability.
A grounding strap or similar protective device should be worn to avoid electrostatic discharge.
