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 LM3S2965 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.

For applications requiring extreme conservation of power, the LM3S2965 microcontroller features

a Battery-backed Hibernation module to efficiently power down the LM3S2965 to a low-power state

during extended periods of inactivity. With a power-up/power-down sequencer, a continuous time

counter (RTC), a pair of match registers, an APB interface to the system bus, and dedicated

non-volatile memory, the Hibernation module positions the LM3S2965 microcontroller perfectly for

battery applications.

In addition, the LM3S2965 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 LM3S2965 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.
