Microcontroller Has Secure On-Device AI Capabilities for Embedded Applications
Nuvoton launched an Endpoint AI Platform microcontroller development, enabled by the company’s latest MCU and MPU silicon, including the NuMicro M55M1 equipped with Ethos U55 NPU, NuMicro MA35D1, and NuMicro M467 series. They leverage NuEdgeWise, a machine-learning tool designed for tinyML development. The NuMicro M55M1 series microcontroller is targeted at machine-learning applications, aided by its Ethos-U55 NPU (neural processing unit) and on-device AI features.
The MCU lets the system watch for events while in low-power mode, without waking up the central processor. It includes an ML model protection mechanism that enhances security by safeguarding ML intellectual property against potential malicious hacking attempts. Supporting Arm Helium technology, the MA35D1 series is a heterogeneous multicore microprocessor for high-end Edge IIoT Gateway, based on a dual-core 64-bit Arm Cortex-A35 core at 800 MHz and a 180-MHz Arm Cortex-M4.
The M467 series is a 32-bit microcontroller based on the Arm Cortex-M4F core with a built-in DSP instruction set and single precision FPU, and can be enhanced with a set of connectivity, I/O, and security peripherals, from Ethernet 10/100 MAC to hardware encryption, decryption, and key storage. The M467 also supports HyperRAM, providing the flexibility to handle different ML models with varying memory size or density requirements.
