NuMaker-X-M55M1D
M55M1 Microcontroller Series
The M55M1 series microcontrollers are based on the Arm® Cortex®-M55 core with an operating frequency of up to 220 MHz. They include Arm® Helium™ DSP technology for enhanced digital signal processing and integrate the Arm® Ethos™-U55 microNPU to accelerate machine learning inference at the edge. The series provides up to 2 MB Flash and 1.5 MB SRAM，and supports the HyperBus interface for external memory expansion. The operating voltage range is 1.7V to 3.6V，and the operating temperature range is -40°C to +105°C，making it suitable for harsh industrial environments.
This series is suitable for embedded applications that require high computing performance，including real-time signal processing，advanced machine learning，high-performance control systems，sensor fusion，smart factory automation，medical devices，and communication systems.
NuMaker-X-M55M1D Development Board
NuMaker-X-M55M1D is a development platform based on the NuMicro® M55M1 series microcontroller.
