Renesas unveils NB-IoT-capable wireless module

Renesas Electronics is expanding its low-power WAN product line with the RYZ024A, which supports Cat-M1 and NB-IoT (Narrowband Internet of Things) internet connectivity.

The device operates without the need for a gateway and consumes just 1µA (microamp) while in power savings mode, significantly less that many other products. The RYZ024A supports extended discontinuous reception (eDRX) and has an extended voltage range from 2.2V to 5.5V which makes it suitable for battery-powered applications.

The RYZ024A offers seamless Cat-M1 wireless connection capability, but the new module adds the option to integrate NB-IoT. While Cat-M1 and NB-IoT are both Low Power Wide Area Network (LPWAN) technologies, NB-IoT uses only a portion of the available spectrum, making it more power efficient and therefore extending the operational life of battery-powered systems.

NB-IoT also offers excellent coverage depth, including underground and in enclosed spaces. The module provides two power amplifier output levels: 20dBm (decibel-milliwatts) and 23dBm, ensuring coverage at the cellular network’s edge as well as deep indoor environments.

The RYZ024A is being developed in collaboration with Sequans and will be fully tested and certified to work with all major radio frequency regulatory specifications defined by organisations such as the Global Certification Forum (GFC) and the PCS Type Certification Review Board (PTCRB).

Renesas will provide all the tools and software that engineers need to design IoT-ready, power sensitive systems based on the RYZ024A, including an evaluation kit, a software stack and RF certifications. Compared to conventional chipset-based designs, designing in the RYZ024A module will reduce the PCB size by 60 percent and cut development time by up to 90 percent, since the product offers full hardware and software support to integrate the RA or RX family of MCUs.
