Congratulations on the 10th Anniversary of RX Family.

Our core technology is wireless, and we provide both hardware and software solutions for wireless connectivity such as wireless LAN modules and networking access points. The first business collaboration with the RX team started when they showed their interests in our ‘Absolutely Must Connect Technology’ and adopted our wireless LAN module (SX-ULPGN-2000) for the RX65N Cloud Kit.

The demo unit developed with the RX65N Cloud Kit could immediately connect to the cloud, we were able to focus on wireless connectivity development to prove our expertise on ‘Absolutely Must Connect wireless even in places where signal reception is poor like exhibition venues. Now, we can prove our strength in wireless technology and the RX65N Cloud Kit’s strong processing power through the demonstration of stable connectivity from sensors to the cloud. Visitors at our exhibition were impressed with the stress-free connectivity we had developed.

With the success story, we look forward to growing our wireless connectivity business with Renesas by enhancing our wireless LAN modules which is imperative to cloud connectivity and working together on RX23W collaboration.

Neona is an Independent Design and Services Company with strong expertise in embedded design and service in IOT/Cloud, such as smart home and smart meter solution. In the last 6 months, we are using RX23W with BT5.0 in our Smart Home Automation and Smart Locker project. It's easy to use even for a beginner and it’s easy and quick to develop the prototype and first level demo to my client. The Smart Configurator makes it much easier to create sample application for BT5.0, which are ready to build and test with just a simple click in the GUI. It’s a breeze to do code modification, as we were able to customize the Cap Touch application for user interface without affecting the rest of the codes. And, the touch calibration works well with the RX Cap Touch Kit.

The combination of Cap Touch with BT5.0 and the rest of the major peripheral functions (analog, digital, USB etc) embedded in a single chip is ideal for my development. And, the most beautiful aspect of RX23W is the size. A small BGA package containing many important features helps to save board space too. It would be ideal if it could include a Wi-Fi functionality in the future.
