The Stellaris ARM Cortex-M4 microcontrollers, called the Stellaris LM4F series, provides floating point and a wide range of capabilities and peripherals. The series encompasses categories of applications that include General MCU, USB, and Advanced Motion Control with up to 16 PWM outputs, with a generous number of serial communication peripherals, including up to 8 UARTs, 6 I2C, 4 SSI/SPI, and 2 CAN controllers.
The Stellaris ARM Cortex-M4F microcontrollers (MCUs), called the Stellaris LM4F series, deliver leading analog integration, floating-point performance and best-in-class power consumption. The LM4F MCUs are the first Cortex-M MCUs to be manufactured in a 65-nanometer process, so you can easily find the right balance between high performance, low power, and price.
TI also recognizes that software drives your time to market so all of the LM4F MCUs are supported by the free-license, royalty-free StellarisWare® software. StellarisWare is a suite of Stellaris-specific APIs that were specifically designed to minimize the cost of software ownership and reduce time to market. Most of these APIs are integrated into ROM, and all software is written in standard C so you can seamlessly develop applications in your tool of choice.
