Renesas launches RX23W module with Bluetooth for IoT devices

1 min read

Renesas Electronics has introduced the RX23W module with Bluetooth for IoT devices.

The module features the RX23W 32-bit RX MCU which supports fully integrated Bluetooth Low Energy communication and comes equipped with an antenna, oscillator and custom-matched circuit. The new module is certified under Radio Law for multiple countries, including Japan and the United States (Note), and is Bluetooth SIG certified.

As a result this eliminates the need for additional RF design work, tuning, or specialized RF knowledge, allowing engineers to use the module as it is, shortening new product development time.

The 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 and helps to improve the development efficiency of IoT endpoint devices such as home appliance, healthcare and sports and fitness equipment.

The RX23W MCU incorporated in the new module supports full Bluetooth 5.0 Low Energy communication support including long-range and 2 Mbps data throughput. It delivers excellent communication characteristics, with reception sensitivity level of −105 dBm at 125 kbps. Built around Renesas’ RXv2 CPU core, the RX23W MCU operates at a maximum clock frequency of 54 MHz together with outstanding power efficiency, making it suited for system control. The RX23W also incorporates Renesas’ security function, the Trusted Secure IP (TSIP), that provides protection against threats to IoT devices such as eavesdropping, tampering, and viruses. In addition, 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 module utilises the same software development environment used for RX MCUs, which means 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 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 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 also be combined with Renesas’ complementary analogue and power offerings to deliver a comprehensive range of solutions for a variety of applications.
