Dual Arm Cortex-A35 cores, graphics acceleration, and various connectivity options, including hardware security encryption and decryption engines, cater to industrial HMI connectivity needs.
Nuvoton unveiled the NuMicro MA35H0 series, a high-performance microprocessor designed for industrial Human Machine Interface (HMI) applications. This MPU is ideal for general control and user interface tasks and excels in a wide range of sophisticated applications across industrial and commercial sectors, including industrial HMI, factory automation, smart buildings, smart homes, smart appliances, smart medical services, and new energy.
With 128 MB of DDR SDRAM stacked inside the compact 24 mm2 LQFP216 package, the need for external memory is eliminated. This saves space, reduces electromagnetic interference (EMI), and cuts costs, making the system more efficient and cost-effective. Security is paramount, and the series supports Arm TrustZone secure boot and other security features to protect valuable code and data. It also boasts high-performance hardware floating-point units (FPU) that enhance digital signal processing (DSP) capabilities. These MPUs are built to withstand harsh environments.
The key specifications are:
- Powered by dual power-efficient 64/32-bit Cortex-A35 cores based on the Armv8‑A architecture
- Cores run at speeds of up to 650 MHz
- Each core is equipped with 32KB of L1 cache
- MPU features 512KB of shared L2 cache
- Industrial-grade internal operating temperature range (Tj) of -40 °C to 125°C.
The series strongly emphasises visual interfaces. It features the Arm NEON Advanced Single Instruction Multiple Data (SIMD) engine, which significantly improves media encoding/decoding, UI, and 2D graphics performance. It has a built-in 2D graphics and video decoder, supporting smooth, crisp LCD output. With robust on-chip security and a range of high-speed connectivity options, it is ideal for creating responsive, attractive, and secure user interfaces for various devices.
The series offers practical security features demanded by today’s applications, including root of trust and secure boot via the internal boot ROM with an OTP key. Built-in hardware cryptographic acceleration functions support secure key storage and OTP memory, isolated from direct CPU access for added security. This series can establish fast encrypted communications, secure sensitive user data, and provide a safe environment for critical applications.
It offers versatile connectivity and I/O features, accommodating various application environments, including megabit Ethernet, USB 2.0 High-Speed Host and Device,etc. It supports 4/5-wire resistive touchscreens without external IC decoders. It provides ample design resources, including a full-featured evaluation board and HMI application demos, facilitating rapid project development. Supported operating systems include Linux, RTOS, and Bare Metal.
