Overview
TI’s Stellaris is the industry’s leading family of robust, real-time microcontrollers (MCUs) based on the revolutionary Cortex™-M3 technology from ARM®. The award-winning Stellaris 32-bit MCUs combine sophisticated, flexible mixed-signal system-on-chip integration with unparalleled real-time multi-tasking capabilities. Complex applications previously impossible with legacy MCUs can now be accommodated with ease by powerful, cost-effective and simple-to-program Stellaris MCUs. With over 140 members in its family, the Stellaris family offers the widest selection of preciselycompatible MCUs in the industry.
The Stellaris family is positioned for cost-conscious applications requiring significant control processing and connectivity capabilities, including motion control, monitoring (remote, fire/security, etc.), HVAC and building controls, power and energy monitoring and conversion, network appliances and switches, factory automation, electronic point-of-sale machines, test and measurement equipment, medical instrumentation and gaming equipment.
In addition to MCUs configured for general-purpose real-time systems, the Stellaris family offers distinct solutions for advanced motion control and energy-conversion applications, real-time networking and real-time
internetworking and combinations of these applications including connected motion control and hard real-time networking. Welcome to the future of microcontrollers!
Why Choose Cortex-M3?
Cortex-M3 is the MCU version of ARM’s V7 instruction set architecture family of cores:
- Optimized for single-cycle flash usage
- Deterministic, fast interrupt processing: always 12 cycles, or just 6 cycles with tail chaining
- Three sleep modes with clock gating for low power
- Single-cycle multiply instruction and hardware divide
- Atomic operations
- ARM Thumb2 mixed 16-/32-bit instruction set
- 1.25 DMIPS/MHz–better than ARM7 and ARM9
- Extra debug support including data watchpoints and flash patching
Capabilities beyond ARM7 for the microcontroller market:
- Requires approximately 1/2 the flash (code space) of ARM7 applications
- 2–4 times faster on MCU control applications
- No assembly code required – ever!
Why Choose the Stellaris Family?
Designed for serious microcontroller applications, the Stellaris family provides the entry into the industry’s strongest ecosystem, with code compatibility ranging from U.S. $1 to 1 GHz.
- Superior integration saves up to U.S $3.28 in system cost
- Over 140 Stellaris family members to choose from
- Real MCU GPIOs – all can generate interrupts, are 5V-tolerant and have programmable drive strength and slew rate control
- Advanced communication capabilities, including 10/100 Ethernet MAC/PHY, USB and USB OTG and CAN controllers
- Sophisticated motion-control support in hardware and software
- Both analog comparators and ADC functionality provide on-chip system options to balance hardware and software performance
- Development is easy with the royaltyfree StellarisWare™ software
