MCX E Series Microcontrollers
The MCX E series of Arm® Cortex®-M4F and Arm® Cortex®-M7 microcontrollers are built for high-reliability industrial and IoT applications, offering robust 5 V operation, up to 4 MB Flash, 512 kB SRAM, and integrated functional safety. Designed for harsh environments, they extends the Kinetis E legacy with enhanced safety (IEC 61508) and EdgeLock® security for a secure-by-design approach.
Key features include CAN-FD, 10/100 Ethernet, low-power serial interfaces, and advanced motor control via 8 FlexTimers(E24) or 3 eMIOS modules(E31). The series supports 24/7 operation up to 135 °C and is backed by precertified safety libraries and documentation for critical applications.
Accelerate your development with the MCUXpresso Developer Experience, VS Code integration, RTOS support, and the FRDM ecosystem for rapid prototyping and streamlined development.
