As an agent of Nuvoton, the editor will explain the NUC980 series of microcontrollers. With the advent of the Internet of Things era, we are enjoying a more convenient life in all aspects, but at the same time we must carefully evaluate the information security issues caused by it. Under this topic, security platform devices are already indispensable. Role. In the operation of microcontrollers and microprocessors, the protection of intellectual property and information security is particularly important. Smart property security focuses on how to effectively protect important information on devices from being stolen through software or hardware, and information security refers to ensuring that hackers can effectively prevent hackers from stealing secrets during communication and data transmission. Data gains illegal benefits.

In addition to the hardware encryption and decryption engine mentioned above, the NUC980 series uses ARM926EJ-S as its core, with an execution speed of up to 300 MHz, and the built-in memory size is 16 MB, 64 MB and 128 MB DDR-II to choose from. The package provides 64-pin, 128-pin and 216-pin LQFP, which greatly reduces PCB size and electromagnetic interference (EMI). Abundant peripheral functions include: 10 sets of UART interfaces, dual Ethernet, 4 sets of CAN 2.0B, 8 sets of USB Host, dual SDIO/ eMMC interfaces, NAND Flash interface, QSPI NAND interface, ISO-7816 interface and high-speed USB 2.0 Host/ Device, etc., can fully meet the application needs of customers, especially for industrial control applications, such as industrial Internet of Things gateways (Gateway), network printer devices, electric meter concentrators, smart home gateways, etc., NUC980 can meet -40℃ to 85℃ Requirements for industrial temperature specifications.

In order to ensure the safety and performance of the product, Nuvoton NUC980 series microprocessor provides a complete hardware encryption accelerator (AES, SHA, HMAC, RSA, ECC), which is compared with software for encryption, decryption and hashing. In addition to improving efficiency and reducing the burden on the CPU, hardware processing allows applications to make full use of the efficiency of the CPU. Furthermore, implementing encryption and decryption operations through hardware can reduce CPU intervention and reduce the possibility of attacks through software. The benefits of the hardware encryption accelerator can be seen from the tests conducted on the Nuvoton NUC980 development platform. There is a significant difference in the speed of software and hardware encryption, especially when the amount of data is larger, the hardware encryption and decryption engine can be more effective. Advantages in processing speed.
