Introduction to Nuvoton's MA35D1 and its significance for IIoT
As the world gears towards a more connected and automated future, the industrial sector is not left behind. Industrial Internet of Things (IIoT) is the use of interconnected devices, sensors, and software in industrial applications for efficient, safe, and cost-effective operations. IIoT has significant implications for the industrial sector, including enhanced supply chain management, predictive maintenance, and remote monitoring. The increased use of IIoT will lead to a reduction in operational costs, improved product quality and safety as well as increased revenue. In this article, we explore how Nuvoton's MA35D1 MPU can help revolutionise the future of IIoT.
What is the MA35D1 MPU?
The MA35D1 MPU is a high-performance, low-power, and cost-effective MPU designed for IIoT applications. The MA35D1 is based on the Arm Cortex-M4F core and is equipped with high-speed connectivity, advanced security, and stacking DDR SDRAM. The MPU is ideal for applications such as edge gateways, industrial controllers, and HMI devices. You can view a good overview of this IIoT powerhouse MPU on Nuvoton's new video:
Key features of the MA35D1 MPU

Crypto Engine: AES256, SHA512, ECC, RSA4096, SM2/3/4
True Random Number Generator (TRNG)
Key Store to protect key
8 Kbit One Time Programmable (OTP) memory
Stacking DDR SDRAM
The MA35D1 MPU supports stacking DDR SDRAM, enabling higher memory density and bandwidth. The stacking DDR SDRAM also reduces the PCB footprint, making it ideal for compact designs. The MA35D1 MPU supports up to 256MB of stacking DDR SDRAM, enabling high-performance data processing in IIoT applications.
MA35D1 provides LQFP and BGA package parts with stacking a 128 MB to 256 MB DDR2/DDR3 SDRAM.
The MA35D1 advantages of stacking the DDR SDRAM:
Fine-tuned DDR SDRAM performance by chip vendor
Easier system design and manufacturing
Lower EMI interference
Reducing PCB layers / area
Reducing BOM and production costs
