M55M1H2LJAE

The NuMicro® M55M1H2LJAE is a new generation AI microcontroller, which delivers up to 110 GOPS of AI computing power, specifically designed for Endpoint AI such as data recognition and intelligent audio. The M55M1H2LJAE is a 32-bit microcontroller based on a 220 MHz Arm® Cortex®-M55 core, featuring an Arm® Ethos™-U55 Neural Processing Unit (NPU) as a coprocessor to accelerate neural network operations. In addition to its outstanding AI performance, the M55M1H2LJAE also includes DSP extensions, vector extensions (Helium), double-precision FPU, 2 sets og 16-channel PDMA controllers and 1 set of  2-channel GDMA controller, making it an ideal choice for embedded applications—especially those requiring intensive computation such as audio processing, communications, digital signal processing, machine learning and sensor fusion.

Flexible Memory & Expansion Options

The M55M1H2LJAE is equipped with up to 1.5 MB of on-chip RAM and 2 MB of Flash memory, and features OctoSPI and HyperBus interfaces to support the expansion of RAM and Flash memory capacity. The M55M1H2LJAE supports a low supply voltage range from 1.71V to 3.6V and operates within a temperature range of -40°C to +105°C.

Energy-Saving Design & Robust Security

For power consumption and security, the M55M1H2LJAE offers five low-power modes and supports a variety of peripherals, including CCAP, DMIC, I2C, SPI, Timer, UART, ADC, and GPIO that can continue to operate in low-power mode. In addition, the M55M1H2LJAE features multi-level security mechanisms, including secure boot, TrustZone®, TRNG, key storage, crypto accelerators, tamper detection, and PSA Certified™ Level 2 compliance, providing reliable protection for IoT and embedded applications.

Flexible IDE Compatibility and Debugging Tools

For development tool support, Nuvoton provides the NuMaker-X-M55M1D evaluation board and the Nu-Link debugger tool. In addition, it supports commonly used development environments such as Keil MDK, IAR EWARM, and Eclipse IDE with GNU GCC.
