Module Launched With Bluetooth And Wireless Communication Abilities

Radio law-certified Bluetooth module combines MCU, antenna and peripheral circuits in a small package for IoT devices

Support for system control and wireless communication on IoT endpoint devices has now become easy, thanks to the RX23W Module with full Bluetooth 5.0 Low Energy. 

Equipped with an antenna, oscillator and custom-matched circuit, the new module also features a 32-bit RX MCU, which supports long-range and 2 Mbps data throughput. It delivers excellent communication characteristics, with a reception sensitivity level of −105 dBm at 125 kbps. 

Additionally, it offers outstanding computing performance, operating at a maximum clock frequency of 54 MHz, ideal for system control. The RX23W MCU has a rich set of peripheral functions that is indispensable to IoT devices, including touch key, USB and CAN functions.

The RX23W also incorporates the Trusted Secure IP (TSIP), which provides robust protection against threats to IoT devices such as eavesdropping, tampering, and viruses.

The new module is certified under Radio Law for multiple countries, including Japan and the United States, and is Bluetooth SIG certified. This eliminates the need for additional RF design work, tuning, or specialised RF knowledge. 

Development Environment

As the new RX23W module utilises the same software development environment used for RX MCUs, developers can work on both system and communication control at the same time. Smart Configurator enables developers to employ a GUI to generate driver code for peripheral functions and Bluetooth, as well as configuring pin settings. QE for BLE enables program generation for custom Bluetooth profiles. 

Developers can also leverage the GUI of Bluetooth Test Tool Suite with which they can perform initial wireless characteristics evaluations and Bluetooth functionality verification. 

The RX23W Module can be combined with Renesas Electronics’ complementary analogue and power offerings to create comprehensive solutions for a variety of applications. Applications include a reference design for a Medical Patch that can monitor body temperature, oxygen saturation (SpO2) and heart rate over a Bluetooth connection using RX23W, and a 48V Mobility Solution that can save the mobility battery status and route history by smartphone connection through RX23W.

Available in a small 6.1 mm x 9.5 mm, 83-pin LGA package, the RX23W allows devices to be made more compact with fewer external components, reducing the bill of materials (BOM) cost and improving IoT endpoint development efficiency of home appliance, healthcare and sports and fitness equipment.

Mass production and shipping of the RX23W Module and its evaluation board have already begun. They can be obtained from Renesas Electronics Corporation.
