Stellaris® ARM® Cortex Gamma -M4f microprocessor

Stellaris arm cortex-m4 microprocessor (called stellaris lm4f Series) can provide floating-point and various functions and peripherals. The series includes general MCU, USB, advanced motion control (up to 16 PWM output) and other application categories, and has a variety of serial communication peripherals (including up to 8 UARTS, 6 I2C, 4 SSI / SPI and 2 can controllers).

Stellaris arm cortex-m4f microprocessor (MCU) (called stellaris lm4f Series) can provide advanced analog integration, floating-point performance and first-class power consumption. Lm4f MCU is the first Cortex-M MCU that will be manufactured by 65 nm process. You can easily find the best balance between high performance, low power consumption and low price.

At the same time, Ti recognizes that software can drive product time to market, so all lm4f MCU can be supported by free license and royalty free stellarisware ® software. Stellarisware is a set of stellaris specific APIs designed to minimize software cost of ownership and accelerate time to market. Most APIs are integrated into ROM, and all software is written in standard C language, so you can easily develop applications in the selected tools.
