RL78/G1H single chip analysis of wireless Wi-SUN FAN protocol

The rapid development of today's technology is driving the continuous innovation of chips. Renesas Electronics Corporation (TSE: 6723), the world's leading semiconductor solution provider, today announced that its sub-GHz wireless solution based on RL78/G1H has passed WI -SUN Alliance FAN certification, which is also one of the important communication standards of the Wi-SUN Alliance (Note 1). This solution is a powerful complement to Renesas Electronics’ RX651 microcontroller (MCU) and RAA604S00 wireless transceiver discrete solutions, further expanding the company’s product portfolio that meets Wi-SUN FAN certification standards.

The new certified solution includes Tessera Technology Inc.’s TK-RLG1H + SB2 evaluation board (Note 2), which integrates Renesas Electronics’ RF-enabled 16-bit RL78/G1H MCU and Wi-SUN FAN communications control software stack. This wireless solution helps customers quickly and easily develop devices compliant with the Wi-SUN FAN specification, reducing the time required for certification during the development process by approximately one year.

Toru Moriya, vice president of the Emerging Markets Business Unit at Renesas Electronics, said: “Wireless frequencies in the Sub-GHz band are relatively less susceptible to obstacles such as walls/buildings, which allows data to be transmitted over long distances in urban environments. Wi -SUN FAN is gaining popularity as a wide-area wireless network standard supporting MESH networks. Our certified RL78-based wireless solution will ease the development burden associated with sensor network applications such as logistics, infrastructure management, and accelerate Wi-Fi -SUN FAN is widely used in realizing smart cities and smart grids." The above is Renesas Electronics' vigorous promotion of the RL78/G1H single-chip solution that supports the wireless Wi-SUN FAN protocol. It requires scientific researchers to continue to innovate in practice, so that Ensure the practicability of the chip.
