Kinetis E Series Microcontrollers NXP Semiconductors Kinetis E Series Microcontrollers are robust, highly scalable MCUs based on the Arm® Cortex®-M0+/M4 Core. The Kinetis E MCUs offer a broad range of memory, peripheral, and package options. These MCUs share common peripherals and pin counts that allows migrating within an MCU family or between MCU families. The Kinetic E MCUs operate at 2.7V to 5.5V supply voltage range and provide exceptional EMC/ESD robustness. These MCUs are designed for complex electric noise environments and high-reliability applications.
