NXP Semiconductors MCX N23x Highly Integrated MCUs

NXP Semiconductors MCX N23x Highly Integrated MCUs operate with a high-performance Arm^® Cortex^®-M33 running up to 150MHz, 1MB of Flash, 352KB ECC RAM, and SmartDMA. The MCX N23x is optimized for cost, memory, and system performance and provides a single-core option with efficient workload distribution to the analog and digital peripherals. NXP supports the MCXN236 device with tools and software, including hardware evaluation boards, software development IDE, example applications, and drivers.

The EdgeLock^® Secure Enclave featured on the MCX N23x is a self-contained, on-die hardware security subsystem with an independent dedicated security core, internal ROM, and secure RAM. The MCUs support state-of-the-art side-channel attack-resilient symmetric and asymmetric crypto accelerators and hashing functions for security services.

The NXP MCX N23x MCUs support the MCUXpresso Developer Experience to ease, optimize, and help accelerate embedded system development.
