# **NuMaker-HMI-MA35D1**

## **Introduction**

The NuMaker-HMI-MA35D1 is an evaluation board for Nuvoton NuMicro MA35D1 series microprocessors, and consists of three parts: a NuMaker-SOM-MA35D16A81 SOM board, a NuMaker-BASE-MA35D1B1 base board and a 7 inch TFT-LCD daughter board. The SOM board integrates core components to simplify the system design, based on MA35D16A887C (BGA312 package, and stacking a 256 MB DDR), PMIC power solution, a 16 GB eMMC Flash, and two Gigabit Ethernet PHY. The NuMaker-HMI-MA35D1-S1 has rich peripherals such as 2 sets of Gigabit Ethernet, USB2.0 high-speed host and device, 2 sets of CAN FD, and SPI, I2C, UART, RS-485 serial communication ports for users to facilitate the evaluation in HMI and industrial control, home appliances, 2-wheel cluster, medical device, new energy applications, ML (Machine Learning) or your creative applications.

The NuMicro MA35D1 series is a heterogeneous multi-core microprocessor targeted to high-end edge IIoT gateway. It is based on dual 64-bit Arm Cortex-A35 cores, and one 180 MHz Arm Cortex-M4 core. Based on the high-performance cores, the MA35D1 series facilities the tiny AI/ML for edge computing. The MA35D1 supports 16-bit DDR2 and DDR3/DDR3L SDRAM. For an easy system design and manufacture, the MA35D1 series also offers LQFP and BGA packages stacked with the DDR2/DDR3L SDRAM and density up to 512 MB, which significantly reduces PCB layer, size and electromagnetic interference (EMI).
