In this article, we would be exploring the latest microcontrollers units which were released in the time period of 2014 to 2015.
To help those of you trying to figure out the latest microcontrollers to use in your project, here is a collection of MCUs which have been launched in the last one year. While this is in no way an exhaustive list, we look forward to hear from you if you think there’s an MCU that you would like to see added to this list.
While building this list, we observed that the growing support for more peripherals, larger memories and smarter CPU features among MCU families show just how much the MCU has changed over the course of a decade. As the amount of integration increases, we see a blur in the line separating the MCUs from the SoCs.
