The Stellaris® LM3S3768 Evaluation Board (EVB) is a compact and versatileevaluation platform for the Stellaris LM3S3768 ARM® Cortex™-M3-basedmicrocontroller. The evaluation board design highlights the LM3S3768microcontroller´s key features including a USB 2.0 full-speed (12 Mbps)controller, Analog-to- Digital Converter (ADC), and serial interfaces.
Features
The Stellaris® USB controller provides full OTG negotiation and support forconnection to non-OTG peripherals or host controllers. With a single USB microABconnector, the LM3S3768 EVB supports On-The-Go (OTG) as well as Host and DeviceUSB capabilities. OTG cables, included in the kit, allow a wide range of USBapplications to be evaluated. A small switch selects between bus-powered andself-powered options. Four ADC signals are paired as two differential channelsto implement a 1 MS/s oscilloscope application on the LCD panel. Theoscilloscope feature set includes USB Host and Device connectivity as well asmicroSD card support. The EVB may be used either as an evaluation platform or asa low-cost in-circuit debug interface (ICDI). In Debug Interface mode, theon-board microcontroller is bypassed, allowing programming or debugging of anexternal target. The Stellaris LM3S3768 Evaluation Board includes the followingfeatures:
50-MHz Stellaris LM3S3768 microcontroller with 128 K flash and 64 K SRAM
2-channel oscilloscope quickstart application
USB OTG Micro-AB connector
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
DC jack for optional 5 V power supply
Standard ARM® 20-pin JTAG/SWD debug connector with input and output modes
LM3S3768 microcontroller I/O available on labeled break-out pads
