Renesas Electronics expands Wi-Sun Fan compliant portfolio

It comprises Tessera Technology Inc.’s TK-RLG1H+SB2 evaluation board, which incorporates the Renesas 16-bit RL78/G1H MCU with integrated wireless functionality, and a Wi-Sun Fan communication control software stack.

The products are suitable for gateway applications such as border routers between Fan and wide area network (Wan) to terminal applications according to requirements such as MCU processing performance, memory capacity, or power efficiency.

By facilitating Fan wide-area mesh networks, these solutions allow customers to develop products in applications including smart meter power usage visualization, smart illumination, sensor management in factories or office buildings, and equipment operation monitoring.

A communication control software for the Wi-Sun certified RL78/G1H solution will be available by September 2020.

“Wireless frequencies in the sub-GHz band are relatively unaffected by obstacles such as  walls and buildings, which makes it possible to transmit data over longer distances in urban settings, and Wi-Sun Fan is gaining popularity as a wide-area wireless network standard with mesh network support,” said Toru Moriya, vice president, emerging market business division at Renesas.

In addition to the RL78 wireless solution, Renesas offers a dual-chip solution combining the 32-bit RX651 MCU and the RAA604S00 wireless communications IC. This solution was Wi-Sun Fan certified in 2019.
