ARM® Processors

Overview for ARM Cortex-M3 Core

The ARM Cortex-M3 processor is the industry-leading 32-bit processor for highly deterministic real-time applications, delivering robust computational performance, exceptional system response to events while meeting the challenges of low dynamic and static power constraints. The Cortex-M3 is highly configurable, enabling a wide range of implementations from those requiring memory protection and powerful trace technology to cost sensitive devices requiring minimal area. A broad range of devices include microcontrollers, automotive body systems, industrial control systems and wireless networking and sensors.

TI's ARM Portfolio Overview

Code Composer Studio® Integrated Environment


TI's Cortex-M3 Advantage

Cortex-M3 MCUs are designed to provide a range of solutions optimized around specific market applications with a variety of performance needs and expectations. These devices provide seamless and scalable integration of fixed-point processing capabilities, embedded flash memory, and rich on-chip analog peripherals with advanced connectivity peripherals. Additionally, Stellaris LM3S MCUs are fully compatible with the new LM4F series.

For more complex applications, the Concerto series of differentiated MCUs combines the powerful ARM Cortex-M3 core with the C28x core of the C20000 in a single MCU package. For intelligent power applications, the Concerto series offer tremendous opportunity. Using controlSUITE, the development tools strategy and software available for the C2000, designers can create an open platform with the goal of maximizing usability and minimizing overall development time.

Additional Cortex-R4 Features Include:
  • Up to 220 MHz, ARM Cortex-R4F CPU
  • Lock-Step CPUs with fail safe detection logic
  • Up to 3 MB of Embedded Flash Memory with ECC
  • Dual 12-bit ADC, 8 redundant channels or 16 shared channels
  • Timer Co-Processer for PWM and input capture
  • Package options: 144 QFP and 337 BGA
