About Microcontrollers

Microcontroller products are sophisticated digital logic devices that can be programmed by the user. Microcontrollers traditionally include working memory, frequently incorporate mixed-signal peripherals, and are generally used with simpler software paradigms focused on repeating a predefined series of tasks. For applications requiring higher performance or parallel processing, designers may instead use field programmable gate arrays.
