NXP MCX E31 MCUs
MCX E31 MCUs - Robust 5 V MCU for Safe, Secure Industrial Automation
The MCX E31 microcontrollers (MCUs) family targets certification to IEC 61508 SIL 2, with a systematic capability aligned to SIL 3, supporting the development of reliable, safe industrial and IoT (IIoT) applications.
With a fail-safe architecture, built-in redundancy and fault tolerance, MCX E31 simplifies the implementation of systems designed to protect both assets and lives. Develop highly dependable industrial solutions with scalable connectivity, advanced security features, and a robust 5V architecture.
The MCX E31 expands on the MCX E24, featuring an improved Arm® Cortex®-M7 core running at up to 160 MHz, supporting 3V to 5V power supplies and enhanced memory configurations with up to 4 MB of Flash and 512 kB of SRAM. These upgrades enable developers to address more demanding applications that require both functional safety and higher processing performance.
These devices are supported by the MCUXpresso Developer Experience to optimize, ease, and help accelerate embedded system development.
