Architectural Overview
1 Architectural Overview
The Luminary Micro Stellaris^® family of microcontrollers—the first ARM® Cortex™-M3 based
controllers—brings high-performance 32-bit computing to cost-sensitive embedded microcontroller
applications. These pioneering parts deliver customers 32-bit performance at a cost equivalent to
legacy 8- and 16-bit devices, all in a package with a small footprint.
The Stellaris^® family offers efficient performance and extensive integration, favorably positioning
the device into cost-conscious applications requiring significant control-processing and connectivity
capabilities. The Stellaris^® LM3S1000 series extends the Stellaris^® family with larger on-chip
memories, enhanced power management, and expanded I/O and control capabilities. The Stellaris^®
LM3S2000 series, designed for Controller Area Network (CAN) applications, extends the Stellaris
family with Bosch CAN networking technology, the golden standard in short-haul industrial networks.
The Stellaris^® LM3S2000 series also marks the first integration of CAN capabilities with the
revolutionary Cortex-M3 core. The Stellaris^® LM3S6000 series combines both a 10/100 Ethernet
Media Access Control (MAC) and Physical (PHY) layer, marking the first time that integrated
connectivity is available with an ARM Cortex-M3 MCU and the only integrated 10/100 Ethernet MAC
and PHY available in an ARM architecture MCU. The Stellaris^® LM3S8000 series combines Bosch
Controller Area Network technology with both a 10/100 Ethernet Media Access Control (MAC) and
Physical (PHY) layer.
The LM3S2110 microcontroller is targeted for industrial applications, including remote monitoring,
electronic point-of-sale machines, test and measurement equipment, network appliances and
switches, factory automation, HVAC and building control, gaming equipment, motion control, medical
instrumentation, and fire and security.
In addition, the LM3S2110 microcontroller offers the advantages of ARM's widely available
development tools, System-on-Chip (SoC) infrastructure IP applications, and a large user community.
Additionally, the microcontroller uses ARM's Thumb®-compatible Thumb-2 instruction set to reduce
memory requirements and, thereby, cost. Finally, the LM3S2110 microcontroller is code-compatible
to all members of the extensive Stellaris^® family; providing flexibility to fit our customers' precise
needs.
Luminary Micro offers a complete solution to get to market quickly, with evaluation and development
boards, white papers and application notes, an easy-to-use peripheral driver library, and a strong
support, sales, and distributor network.
