Bluetooth module for IoT system control, wireless communication
Featuring the RX23W 32-bit RX MCU supporting fully integrated Bluetooth Low Energy communication, the new RX23W module is equipped with an antenna, oscillator and custom-matched circuit. The module is certified under Radio Law for multiple countries, including Japan and the United States (Note), and is Bluetooth SIG certified – eliminating the need for additional RF design work, tuning, or specialized RF knowledge.
“As development cycles for IoT devices become shorter, the development burden increases,” says Sakae Ito, Vice President of IoT Platform Business Division at Renesas. “We are pleased we can now announce the release of our first Bluetooth communication module based on the Renesas RX MCU, thereby helping to make the development process more efficient.”
In addition, says the company, the module’s very small 6.1 mm x 9.5 mm, 83-pin LGA package makes it possible to design more compact devices with fewer external components, reducing the bill of materials (BOM) cost. This improves the development efficiency of IoT endpoint devices such as home appliance, healthcare and sports and fitness equipment.
The RX23W MCU incorporated in the module supports full Bluetooth 5.0 Low Energy communication support including long-range and 2 Mbps data throughput. Other features include a reception sensitivity level of -105 dBm at 125 kbps and a maximum clock frequency of 54 MHz along with “outstanding” power efficiency, making it ideally suited for system control.
The RX23W also incorporates the company’s exclusive security function, the Trusted Secure IP (TSIP), that provides robust protection against threats to IoT devices such as eavesdropping, tampering, and viruses. In addition, the RX23W MCU has a variety of peripheral functions including touch key, USB, and CAN functions.
The new RX23W module utilizes the same software development environment used for RX MCUs, enabling developers to 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 developers to generate programs for custom Bluetooth profiles. The Bluetooth Test Tool Suite provides a GUI that allows developers to perform initial wireless characteristics evaluations and Bluetooth functionality verification. These tools are well suited to the various phases of development, providing support for developers from the initial stages through applied product development, and substantially boosting efficiency.
The RX23W module can be combined with the company’s complementary analog and power offerings to create comprehensive “Winning Combinations” solutions for a variety of applications. Applications includes 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.
The RX23W module is available now at $6.60 per 10,000-unit quantities. A target board for evaluation is also available at $50 per unit, and it is available now.
