Description

Stellaris evaluation kits provide a low cost, effective means of evaluating Stellaris Family microcontrollers. Evaluation kits focus on a single set of tools and a single Stellaris family member.

Features

The Stellaris® LM3S3748 Evaluation Board (EVB) is a compact and versatile evaluation platform for the Stellaris LM3S3748 ARM® Cortex™-M3-based microcontroller. The evaluation board design highlights the LM3S3748 microcontroller's key features including a USB 2.0 full-speed (12 Mbps) Host/Device controller, Analog-to-Digital Converter (ADC), and serial interfaces.

The LM3S3748 EVB has connectors for both embedded USB Host and USB Device operation, allowing a range of USB application options to be evaluated. In USB Device mode, a small switch selects between bus-powered and self-powered options. Four ADC signals are paired as two differential channels to implement a 1 MS/s oscilloscope application on the LCD display. The oscilloscope feature set includes USB Host and Device connectivity as well as SD card support. The EVB may be used 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 target. The kit features:

• 50-MHz Stellaris LM3S3748 microcontroller with 128 K flash and 64 K SRAM
• 2-channel oscilloscope quickstart application
• USB Host and Device connectors
• Bus-powered or self-powered USB Device support
• Simple setup: USB cable provides serial communication, debugging, and power
• Color LCD graphics display with 128 x 128 pixel resolution
• User LED and navigation switch with press-to-select functionality
• 8Ω magnetic speaker with amplifier
• microSD card slot
• USB interface for debugging and power supply
• DC jack for optional 5 V power supply
• Standard ARM® 20-pin JTAG/SWD debug connector with input and output modes
• LM3S3748 microcontroller I/O available on labeled break-out pads
