# About 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 $1 to 1 GHz.

- Superior integration saves up to $3.28 in system cost
- Over 130 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 royalty-free Stellaris Peripheral Driver Library's high-level API interface to the entire Stellaris peripheral set

- Stellaris microcontrollers feature the ARM® Cortex™-M3 microcontroller core:

- 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

- Stellaris microcontrollers offer capabilities beyond ARM7 for the microcontroller market:

- Requires approximately half the flash (code space) of ARM7 applications
- 2–4 times faster on MCU control applications
- No assembly code required - ever!
