The microprocessor features dual cores, security, and graphics for industrial HMI applications, enabling a seamless interface experience.


Nuvoton announces the NuMicro MA35H0 series, a microprocessor for industrial Human Machine Interface (HMI) applications, control, and tasks within industrial and commercial areas, including industrial HMI, factory automation, buildings, homes, appliances, healthcare, and energy.

The microprocessor is powered by dual 64/32-bit Cortex-A35 cores under the Armv8-A architecture, with speeds up to 650 MHz, 32KB of L1 cache per core, and 512KB of shared L2 cache. It includes 128 MB of DDR SDRAM within the 24 mm2 LQFP216 package, eliminating the need for external memory and reducing electromagnetic interference (EMI) and costs.

The new series supports Arm TrustZone secure boot and security features to protect code and data. It has hardware floating-point units (FPU) for digital signal processing (DSP) capabilities. It operates within a temperature range from -40 °C to 125°C, suitable for harsh conditions.

The microprocessor is designed for modern user interfaces, incorporating the Arm NEON Advanced Single Instruction Multiple Data (SIMD) engine to improve media encoding/decoding, UI, and 2D graphics performance. It features 2D graphics and video decoding, supporting 60fps 1280×800 LCD output. The MA35H0 series offers security features and connectivity options, making it suitable for powering user interfaces across devices.

The series includes security features such as root of trust and secure boot through the internal boot ROM with an OTP key. It has a cryptographic acceleration function, supporting secure key storage and OTP memory, isolated from CPU access for security. These features enable encrypted communications, protect user data, and provide a safe application environment.

The integrated LCD controller supports user interfaces up to 1280×800 resolution, with 2D graphics acceleration and on-chip JPEG and H.264 video decoding, enabling video at 60fps.

The series offers connectivity and I/O features, including Ethernet with IEEE 1588v2, USB 2.0 High-Speed Host and Device, SDIO3.0, QSPI, CAN FD, UARTs, and I2S. It also supports 4/5-wire resistive touchscreens without external IC decoders.
