RX23W Bluetooth LE Wireless Solution

Bluetooth Low Energy (LE) is a low energy mode of Bluetooth wireless technology that has an effect on power consumption, especially for battery-operated applications. The attractive point of Bluetooth LE lies in that it can operate while being connected to applications for smartphones and tablets. Renesas Bluetooth LE solutions provide smart connections with the lowest level of power consumption in the industry and can be used in applications such as healthcare and fitness devices, home electric appliances and RFID tags that use beacons to connect them with smartphones at low power consumption without wires.

Included in Renesas' Bluetooth LE product portfolio is the RX23W 32-bit microcontroller (MCU) solution that offers built-in security functions essential for Bluetooth 5.0 LE and IoT devices, as well as a wealth of peripheral functions such as touch keys, USB and CAN, and it provides system control for devices and wireless communication on a single chip. The RX23W supports full features including long range and mesh network for Bluetooth 5.0 LE. And, it supports "Channel Selection Algorithm #2", making it is more resistant to interference from other 2.4GHz RF signals and it realizes stable communication even in environments with radio interference.

S/W & Tools

Bluetooth Low Energy Protocol Stack for the RX Family

The Bluetooth Low Energy protocol stack is the software required to operate the RX23W MCU. It conforms to the Bluetooth v5.0 specification and all LE functions of Core Specification v5.0 can be supported. In addition, three types of libraries are provided depending on the function set, so that a configuration suitable for the specifications of the end product can be selected.

Bluetooth qualified 56 types (as of December 2019) of standard Profiles/Services are available.

The profile is generated from QE for BLE[RA,RE,RX]. You can also design and generate a custom profile. Renesas also provides sample programs as a reference for your program development. The sample programs will be further expanded in the future.
