CHAPTER 1
Stellaris® LM3S6965 Evaluation Board
The Stellaris® LM3S6965 Evaluation Board is a compact and versatile evaluation platform for the
Stellaris LM3S6965 ARM® Cortex™-M3-based microcontrolle r. The evaluation kit uses the
LM3S6965 microcontroller’s fully integrated 10/100 Ethernet controller to demonstrate an
embedded web server.
You can use the board either as an evaluation platform or as a low-cost in-circuit debug interface
(ICDI). In debug interface mode, the on-board microcontroller is bypassed, allowing programming
or debugging of an external targ et. The kit is also comp atible with high-performance extern al JT AG
debuggers.
This evaluation kit enables quick evaluation, prototype development, and creation of applicationspecific designs for Ethernet networks. The kit also includes extensive source-code examples,
allowing you to start building C code applications quickly.
