Stellaris LM3S3768 User Manual

Stellaris® LM3S3768
USB OTG Evaluation Kit

The Stellaris® LM3S3768 Evaluation Board (EVB) is a
compact and versatile evaluation platform for the
Stellaris LM3S3768 ARM® Cortex™-M3-based
microcontroller. The evaluation board design highlights
the LM3S3768 microcontroller's key features including
a USB 2.0 full-speed (12 Mbps) controller, Analog­to-Digital Converter (ADC), and serial interfaces.

Features

The Stellaris® USB controller provides full OTG
negotiation and support for connection to non-OTG
peripherals or host controllers. With a single USB
microAB connector, the LM3S3768 EVB supports
On-The-Go (OTG) as well as Host and Device USB
capabilities. OTG cables, included in the kit, allow a
wide range of USB applications to be evaluated. 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 panel. The
oscilloscope feature set includes USB Host and
Device connectivity as well as microSD 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 Stellaris LM3S3768 Evaluation
Board includes the following features:

 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
