Getting to know Control + Automation

Learn more about the Texas Instruments Control + Automation Microcontrollers.


Control + Automation microcontrollers are comprised of two families with two main architectures today: F28M3x microcontrollers, featuring the C28x + ARM® Cortex®-M3; and TM4C12x microcontrollers featuring the ARM® Cortex®-M4F. These architectures provide integrated solutions for industrial applications which require control, connectivity or system automation.

F28M3x microcontrollers

Control + Automation F28M3x microcontrollers bring together connectivity and control by combining an ARM Cortex-M3 core with a C28x core onto one device. With F28M3x microcontrollers, designers get the best of both worlds by using the ARM core to process application and communication tasks while using the C28x to run demanding control loops. In addition, the F28M3x includes a variety of analog, control and communication peripherals, providing a truly integrated single chip solution.

C28x core

DSP performance in a microcontroller

The F28M3x microcontroller uses a central 32-bit CPU core, called C28x, coupled with a highly-optimized peripheral and interrupt management bus. As a cross between a general microcontroller and a digital signal processor, the C28x core brings the code density and execution speed of a DSP with the ease of use and accessibility of a microcontroller.

PWM signal generators

The most flexible, configurable and highest-performing PWM signal generators in its class

With unparalleled flexibility of waveform creation and synchronization, the PWMs can generate the waveforms and meet timing requirements of the toughest control applications. With features such as high resolution duty cycle control, enhanced deadband support and asynchronous PWM trips, applications will be able to run at higher frequencies, respond more quickly to changing loads and respond near instantaneously to unstable system conditions.

Analog technology

The analog integration and performance you need to reduce cost and decrease board area

Fast ADCs with 16-bit precision provide accurate feedback in the timeframe you require. High-speed comparators allow you to accurately test your feedback signals and quickly shutdown or alter system behavior. Integrated opamps reduce external component cost. Internal oscillators, watchdogs, VREGs and power on reset/brown-out reset protection give you the system support you need without the extra cost and hassle of implementation.
