Wireless communication is the one of the hot topics in the various applications including the industrial area.
We here "IoT" more and more and most of the design conferences has the section that is focused on wireless network.
Today's product is ML7404, RF LSI for LPWA (Low Power WIde Area) that is introduced LAPIS Semiconductor.
You may not be familiar with this Japanese company, but they are producing the unique and high performance LSIs targeting the various application.
LAPIS Semiconductor ML7404
Here is the introduction from their site.
"The ML7404 is the first wireless communication LSI in the industry to feature LPWA dual-mode functionality, supporting both Sigfox standard(subscription-based LPWA using unlicensed sub-GHz), which has been adopted in more than 30 countries and expanding in metropolitan areas including Japan, and the international protocol IEEE802.15.4k that is extremely robust against interference from the same system and has the capacity to cover more terminals under one network."
This chip supports dual frequency bands, 750MHz - 960MHz and 315MHz - 960MHz depending on the LPWA mode, Sigfox or IEEE802.15.4k.
It seems like the evaluation kit will be available soon as the website says
"An optional evaluation kit bundles sample programs (simple MAC) and various test scenarios, with reference module designs currently being prepared. In addition, full support is offered, including manuals and tools that can be downloaded from LAPIS Semiconductor’ website (registration required). And in the future, communication modules integrating the ML7404 along with low power protocol stacks for IEEE802.15.4k will be released from partner companies."
