New IC supports Sigfox and IEEE802-15-4k protocols and lengthens range 10x for IoT products.

ROHM and LAPIS Semiconductor have collaborated on the world’s first LPWA (Low Power Wide Area) IC for a broad range of wireless IoT applications.

This IC is being called the ML7404 and is the first chip in the industry to have dual-mode capabilities which support the standard Sigfox, a subscription-based protocol using sub-GHz, and the popular IEEE802-15.4k international protocol. Sigfox is gaining popularity, now being adapted in over 30 countries. The IEEE802.15.4k protocol has excellent resilience against noise. The combination of the two protocols in one IC allows an unparalleled level of flexibility in industrial and IoT applications.

Rohm and LAPIS are working with module companies, and devices containing this chip will be available soon. The stack for the IEEE802.15.4k protocol will also be offered as open source from stack vendors.

In recent history, developers have been using LPWA on the sub-GHz band because licensing is not necessary. Because there is no standard on specific RF frequencies from one country to another, it is useful to have the kind of flexibility that dual-band products provide, and can apply to a broad array of industrial and IoT products.

With a history of providing leading-edge sub-GHz wireless technology for low power radio base stations, LAPIS and ROHM are making strides with IoT. This new LPWA chip that supports dual-bands will help developers with time-to-market and an impressive feature set.
