RX23W module with full Bluetooth 5.0 low energy support targets IoT endpoint devices

From Renesas Electronics comes the RX23W module with full Bluetooth 5.0 low energy support for system control and wireless communication on Internet of Things (IoT) endpoint devices.

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 USA, and is Bluetooth SIG certified which is said to eliminate the need for additional RF design work, tuning, or specialised RF knowledge. This in turn means customers can 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 cost, says Renesas which also states that 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 also supports long-range and 2 Mbps data throughput. Its communication characteristics offer 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 suiting it to system control. The RX23W also incorporates Renesas’ exclusive security function, the Trusted Secure IP (TSIP), that the company states provides robust protection against threats to IoT devices such as eavesdropping, tampering, and viruses.

A set of peripheral functions includes touch key, USB, and CAN functions.

The RX23W module uses 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.
