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 extend 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.

I need a deterministic 5 V motor or power conversion controller that is robust against EMI and line disturbances and still meets safety requirements. What’s the cleanest single-chip path?
Use MCX E24x for rugged 5.5 V operation, 112 MHz M4F and eight FlexTimers synchronized with fast ADC and comparators for tight PWM and ADC alignment. It is SafeAssure ready for IEC 61508 SIL 2 with ECC on Flash and SRAM and includes EdgeLock Accelerator CSEc for authenticated boot and update. The FRDM-MCXE247 platform and RTCESL deliver measurable FOC and digital power examples on day one.
We’re building a harsh environment edge hub that must move traffic across multiple CAN FD networks and time-aware Ethernet without compromising control loop determinism. What is the best topology?
Choose MCX E31x when you need up to six FlexCAN FD plus 10/100 Ethernet with TSN. Run fast loops and filtering on the M7 at 160 MHz with 96 KB TCM for low-latency ISRs, and push bulk I/O through DMA and the Ethernet MAC while maintaining determinism. For smaller hubs with three or fewer CAN and one Ethernet, MCX E24x balances features and power at 5 V.
We want measurable motor control gains (loop rate, dead time precision, phase current quality) without external glue; what changes with MCX E timers?
MCX E24x's eight FlexTimers provide complementary PWM, dead-time insertion and ADC trigger alignment for high-fidelity FOC and digital power, while MCX E31x uses eMIOS blocks tuned for complex timing. Pair with on-chip comparators and multi ADC to reduce latency and component count; FRDM-MCXE247 demos show low CPU load at typical FOC rates.
What accelerates rapid first-pass bring-up for a 5 V safety-grade CAN FD and Ethernet design including pins, clocks, secure boot, RTOS and testable KPIs?
MCX E24x and E31x integrate with the MCUXpresso Developer Experience including IDE/SDK, secure provisioning and pin, clock and peripheral tools with Zephyr support. Use FRDM-MCXE247 for ready Ethernet, CAN FD and ADC/PWM projects and for bring-up scripts that log ISR latency, loop jitter, throughput and energy before hardware freeze.
