Stellaris microcontrollers (MCUs) were the first MCU on the market to be based on the ARM Cortex-M core, an architecture that has quickly become a top choice for many developers across the globe. Since its establishment, the Stellaris product line has remained true to its original goals – providing the broadest portfolio of highly connected, low cost and easy-to-use 32-bit microcontrollers. The latest Stellaris LM4F series refines the offering of MCUs, greatly improving performance and raising features to a new level of quality.

Leading analog integration, best-in-class low-power consumption and floating-point performance in next generation Stellaris ARM® Cortex™-M microcontrollers Stellaris LM4F microcontrollers take advantage of two significant technologies: the latest ARM Cortex-M4F core and the design techniques and process technologies perfected at Texas Instruments. The result is a 32-bit microcontroller family with processing performance that is more effective per clock cycle, integrated mixed-signal circuits that are on par with traditional standalone components, flash memory with erase-write endurance that is best-in-class and power consumption that is highly competitive with other 32-bit MCUs in both active and standby modes. Such qualities will further increase the breadth of applications powered by Stellaris
MCUs and enable applications that were not previously feasible.
The major features of Stellaris ARM Cortex-M4F microcontrollers are depicted in the block diagram of Figure 1. A more thorough list can be found in the product data sheets.
