Stellaris® LM3S9D90 Evaluation Kit Overview
Texas Instruments' Stellaris® LM3S9D90 Evaluation Board Kit (EK-LM3S9D90) is a low-cost
platform for evaluation of the LM3S9D90 microcontroller. The kit includes two boards, the
EK-LM3S9D90 evaluation board, and the In-Circuit Debug Interface (BD-ICDI) board.
The EK-LM3S9D90 board includes the LM3S9D90 ARM® Cortex™-M3 Microcontroller, a 10/100
Mbit Ethernet port, a full-speed USB-OTG port, connectors for inteface to the BD-ICDI board, and
oversized pads for easy connection to the microcontroller GPIO ports.
The BD-ICDI board is a USB full-speed JTAG/SWD debugger board. It includes a USB miniB
connector for connection to a USB PC port, and two shrouded header connectors for connection to
the EK-LM3S9D90 board.
Development of software for the EK-LM3S9D90 is simplified by using Texas Instruments’
comprehensive StellarisWare® peripheral driver library and ARM development tools from our tools
partners. The Stellaris® LM3S9D90 Evaluation Board Kit includes the two boards described, a
documentation CD, and cables. All design files are provided on the EK-LM3S9D90 CD.

–Stellaris® Firmware Development Package with example source code
Using the EK-LM3S9D90
The recommended steps for using the EK-LM3S9D90 evaluation kit are:
1. Follow the Quickstart guide included in the kit. The Quickstart guide will help get the
EK-LM3S9D90 Evaluation Board up and running in minutes.
2. Use your preferred ARM tool-chain and the Stellaris Peripheral Driver Library to
develop an application. Software applications are loaded using the BD-ICDI board. See
Chapter 3, “Software Development,” for the programming procedure. The StellarisWare
Peripheral Driver Library Software Reference Manual contains specific information on
software structure and function.
3. Customize and integrate the hardware to suit an end application. This user's manual is an
important reference for understanding circuit operation and completing hardware modification.
