Nuvoton in Taiwan has launched a processor with two ARM Cortex-A35 cores, NEON instructions and LCD controller  for industrial HMI interface applications with 128 MB of DRAM memory in the package.

The NuMicro MA35H0 series from Nuvoton can also be used for general control and user interface applications across industrial and commercial applications such as HMI, factory automation, smart buildings, smart homes, smart appliances, smart medical services, and new energy.

The MA35H0 is built around dual power-efficient 64/32-bit Cortex-A35 cores based on the Armv8-A architecture, running at up to 650 MHz, with 32KB of L1 cache for each core, and 512KB of shared L2 cache.

The 128 MB of DDR SDRAM is stacked inside the 24 mm2 LQFP216 package, saving space and reducing electromagnetic interference (EMI) and cost and has an industrial-grade internal operating temperature range (Tj) of -40 °C to 125°C.

It also features high-performance hardware floating-point units (FPU) for digital signal processing (DSP) as well as the ARM NEON Advanced Single Instruction Multiple Data (SIMD) engine, dramatically improving media encoding/decoding, UI, and 2D graphics performance.

It has built-in 2D graphics and video decoder, with smooth, crisp 60fps 1280×800 LCD output support and also supports the ARM TrustZone secure boot and other security features to safeguard code and data.

The MA35H0 emphasizes the practical security features that today’s applications demand, including the root of trust and secure boot via the internal boot ROM with an OTP key. Hardware cryptographic acceleration functions (AES, SHA, ECC, RSA, SM2/3/4, and TRNG) are built-in, supporting the secure key store and OTP memory, which are walled off from direct CPU access for additional security. The MA35H0 series can easily establish fast encrypted communications, keep sensitive user data safe, and offer a secure environment for critical applications.

The built-in LCD controller provides a sharp and responsive user interface at up to 1280×800, aided by 2D graphics hardware acceleration and fast on-chip JPEG and H.264 video decoding – capable of providing full-screen video at 60fps.

Interfaces include megabit Ethernet with IEEE 1588v2, USB 2.0 High-Speed Host and Device, SDIO3.0, QSPI, CAN FD, UARTs, and I2S. The chip also supports 4/5-wire resistive touchscreens without external IC decoders.

A full-featured evaluation board (NuMaker-HMI-MA35H0-A1) and HMI application demos include an EV charging station, industrial control, coffee machine, and vehicular speed and data display. OS support includes Linux, RTOS, and Bare Metal.
