For current users of 8- and 16-bit MCUs, Stellaris™ with Cortex-M3™ offers a direct path to the strongest ecosystem of development tools, software and knowledge in the industry. Designers who migrate to Stellaris™ will benefit from great tools, small code footprint and outstanding performance.

Importantly, Designers can enter the ARM© ecosystem with full confidence in a compatible roadmap from $1 to 1 GHz. You will never need to change architectures again.

For users of current 32-bit MCUs, the Stellaris™ family offers the industry’s first implementation of Cortex-M3™ and the Thumb-2 instruction set. With blazingly-fast responsiveness, Thumb-2 technology combines both 16-bit and 32-bit instructions to deliver the best balance of code density and performance. Thumb-2 uses 26 percent less memory than pure 32-bit code to reduce system cost while delivering 25 percent better performance.

The era of pervasive 32-bit computing, control and communication has arrived.

Stellaris LM3S300

The Stellaris LM3S3xx microcontrollers feature 16K bytes of single cycle flash and 2K to 4K bytes of single cycle SRAM in speeds up to 25 MHz. Also included are up to 6 PWM generators suitable for motion control. Analog features include up to 3 analog comparators and up to 8 channels of 10-bit ADC at up to 500K samples per second.
