Renesas launch RX23W 32-bit MCU with integrated Bluetooth for IoT applications, samples and evaluation board available from Anglia


Renesas has introduced the RX23W – a 32-bit microcontroller (MCU) featuring Bluetooth® 5.0 for IoT endpoint devices such as home appliances and healthcare equipment. By combining Bluetooth 5.0 with Renesas’ Trusted Secure IP on its popular high-performance RX MCU family, Renesas offers customers an optimized single-chip solution for system control and wireless communication, while also providing a more secure way to answer the Bluetooth security risks such as eavesdropping, tampering, and viruses.

The new RX23W MCU is based on Renesas’ RXv2 core, which provides outstanding computational performance with improved FPU and DSP functions and operates at a maximum clock frequency of 54 MHz. The RX23W provides full Bluetooth® 5.0 Low Energy support including long-range and mesh networking functions and achieves the industry's lowest level reception mode peak power consumption at 3.0 mA. Furthermore, it integrates a rich set of peripheral functions that are indispensable for IoT equipment, including security, touch key, USB, and CAN functions. These functions allow the RX23W to implement both system control and Bluetooth wireless functions for IoT endpoint equipment such as home appliances, health care equipment, and sports and fitness equipment on a single chip. In addition, the RX23W's Bluetooth mesh functions make it optimal for industrial IoT equipment collecting sensor data within a factory or a building.

The RX23W MCU has full functional support for Bluetooth 5.0 Low Energy and outstanding reception characteristics. It supports long distance communication (long range: 400 m), 2 Mbps (megabit per second) data throughput, and Bluetooth mesh networking, supporting the full functionality of Bluetooth 5.0 Low Energy. Furthermore, the RX23W's 3.0 mA reception mode peak current is the industry's lowest level and it has a reception sensitivity level of -105 dBm at 125 Kbps. The RX23W also includes a dedicated Bluetooth® high-precision low-speed on-chip oscillator with an internal matching circuit, eliminating the need for external matching circuits and external capacitors. This reduces both BOM (bills of materials) costs and circuit board areas, resulting in lower IoT equipment manufacturing costs.

Functional Block Diagram

In addition to a Bluetooth 5.0 basic protocol stack package, Renesas provides API functions that conform to all standard profiles, including a Health Thermometer Profile (HTP), an Environment Sensing Profile (ESP), and an Automation I/O profile (AIOP). These allow users to start prototype development and evaluation quickly and can speed up the user's development process.

Renesas also provides a Smart Configurator, implemented in a GUI, that can generate all types of MCU peripheral function driver code and pin settings for the e2 Studio integrated development environment (IDE) to generate the Bluetooth driver code. Renesas also developed a QE for BLE that can generate programs for custom profiles and embed them in user application programs to support application program development. Renesas have also developed a Bluetooth Trial Tool Suite that allows users to perform initial wireless characteristics evaluations and Bluetooth functional verification in a GUI.

The RX23W is a secure communications MCU for the IoT, it integrates Renesas' Trusted Secure IP (TSIP) as part of its built-in hardware security engine. The TSIP driver uses strong encryption key management with hardware accelerators to securely boot customers' IoT devices and protect them from security threats.

The RX23W MCU is available in both 7mm x 7mm 56-pin QFN and 5.5mm x 5.5mm 85-pin BGA packages with 512 KB of on-chip flash memory.

RX23W Target Board

The Target Board for the RX family provides an entry point to evaluation, prototyping and developing for the RX MCU family. The board also incorporates an emulator circuit, this allows it to be used for customers own application design without the need for further tool investments. This board provides through-holes for pin headers that allow access to all MCU signal pins, allowing an easy prototyping with a breadboard. One unique feature of the Target Board for RX family concept is the reuse of the same PCB for all variations, proving the RX MCU family has a common pin assignment concept, which allows a seamless transition between different RX Groups and Series using the same package version. The RX23W target board includes antennas and has already acquired certification under Radio Law.
