LM3S9B92 microcontroller characteristic parameters and Stellaris robot evaluation board
TI brings 32-bit features and all the advantages of an ARM Cortex-M3-based microcontroller to the broad microcontroller market. For the current 8-bit and 16-bit MCU users, Stellaris using Cortex-M3 provides a powerful development tool, software and knowledge system. By porting to Stellaris, users can benefit from very good tools, small code size, and outstanding performance. More importantly, designers can enter the ARM system with confidence.
For current 32-bit MCU users, the Stellaris family offers the industry's first Cortex-M3 design and Thumb-2 instruction set. Thumb-2 technology has ultra-fast response speed, integrates 16-bit and 32-bit instructions, and best balances code density and performance. Thumb-2 uses 26% less memory than pure 32-bit code, reducing system costs while increasing performance by 25%. The TI Stellaris family of microcontrollers is an ARM Cortex-M3-based controller that brings high-performance 32-bit computing to cost-sensitive embedded microcontroller applications.

Stellaris Robot Evaluation Board (EVALBOT)
The Stellaris Robot Evaluation Board (EVALBOT) is a robotic evaluation platform for the Stellaris LM3S9B92 microcontroller. The EV kit utilizes TI's analog components for motor drive, power, and communications functions. Just a few minutes to complete the assembly, EVALBOT's electronic components can be put into use.
Three AA batteries power the EVALBOT while roaming. EVALBOT automatically selects the USB power supply when connected to a PC or debugging as a USB device. Test points are provided for all major EVALBOT signals. Two 20-pin headers enable future wireless communications using standardized TI low-power embedded radio modules (EM boards). There are other microcontroller signals on the rows of rows of pads located near the microcontroller.
EVALBOT has factory-installed quick start software in its on-chip flash memory. For software debugging and Flash programming, the Integrated In-Circuit Debugging Interface (ICDI) requires only one USB cable for debugging and serial port functions.
