Renesas Electronics Introduces 32-bit RX23W Microcontroller to Provide Bluetooth 5.0 for IoT End Devices

Tokyo, Japan, December 4, 2019 – Renesas Electronics Corporation (TSE: 6723), a leading global supplier of semiconductor solutions, today announced the RX23W, a Bluetooth 5.0-enabled 32-bit microcontroller (MCU) that It is especially suitable for IoT terminal equipment such as household appliances and medical equipment. By combining Bluetooth 5.0 with its Trusted Secure IP security capabilities on its popular high-performance RX MCU series, Renesas provides customers with a single-chip solution optimized for system control and wireless communication, while also providing a A more secure way to deal with Bluetooth security risks such as eavesdropping, tampering and viruses.

Daryl Khoo, vice president of product marketing for the IoT Platform Business Unit at Renesas Electronics, said: “While devices supporting Bluetooth 5.0 Low Energy are not uncommon in the market, Renesas Electronics has contributed to this wireless network by placing a high priority on security and privacy. The ubiquity of wireless technology adds value. Recent security concerns clearly demonstrate that Bluetooth implementations are becoming more complex as more core use cases are defined, and that better, more secure connections are urgently needed. Sa believes that its advantages in hardware security performance can greatly complement the security risks when deploying Bluetooth 5.0 low energy applications. The Renesas single-chip solution supports simultaneous application, communication and security. I am very happy that Renesas can provide We are so well positioned for our flagship RX range, which has a proven track record in reliability and safety.”

Based on Renesas’ RXv2 core (Note 1), the new RX23W has excellent computing performance, and features improved FPU (Note 2) and DSP functions, capable of running at a maximum clock frequency of 54 MHz. The RX23W offers full Bluetooth 5.0 Low Energy support, including long-range and mesh networking capabilities, and achieves the industry’s lowest peak power consumption in receive mode at 3.0 mA. In addition, the RX23W integrates various functions that are indispensable for IoT devices, including security, touch keys, USB and CAN. These features help the RX23W implement system control and Bluetooth wireless functionality on a single chip for IoT end devices such as home appliances, medical equipment, and sports and fitness equipment. Additionally, the RX23W’s Bluetooth mesh networking capabilities are ideal for industrial IoT devices to collect sensor data within a factory or building.

Key features of the RX23W MCU:

  •   Full support for Bluetooth 5.0 Low Energy with excellent reception characteristics

The RX23W supports long-distance communication (up to 400 m), data throughput of 2 Mbps (megabits per second), Bluetooth mesh networking, and the full capabilities of Bluetooth 5.0 Low Energy. In addition, the RX23W’s receive mode peak current can reach 3.0 mA (the industry’s lowest level), and the receive sensitivity at 125 Kbps is -105 dBm.

  •   Basic stack package and all standard configuration files

In addition to the Bluetooth 5.0 basic stack package, Renesas provides API functions that conform to all standard profiles, including Health Thermometer Profile (HTP), Environmental Sensing Profile (ESP), and Automatic I/O Profile (AIOP). ). To help users quickly start the development and evaluation of prototypes, and speed up the development process.

  •   Revolutionary development environment that allows simultaneous system control and communication control development

Renesas has installed a new Smart Configurator for generating peripheral module driver code and pin configuration of various MCUs in the integrated development environment e2 Studio, which can generate program code for Bluetooth drivers. Renesas has also developed QE for BLE, which can generate programs for custom profiles and embed them in user applications to support application development. Renesas also introduced the Bluetooth Trial Tool Suite (Bluetooth Trial Tool Suite) that allows users to perform initial wireless performance evaluation and Bluetooth functional verification in the GUI. The RX23W target board includes a Radio Act certified antenna. The suggested reference price for this board is $55/set (tax excluded).

  •   Secure Communication MCU for IoT

The RX23W integrates Renesas’ Trusted Secure IP (TSIP) as part of its built-in hardware security engine. The TSIP driver employs strong cryptographic key management with hardware accelerators to securely boot IoT devices and protect them from security threats; the product will also receive Cryptographic Algorithm Validation Program (CVAP) certification.

  •   Reduce BOM cost through high integration

The RX23W contains a dedicated Bluetooth high-precision low-speed on-chip oscillator that eliminates the need for external matching circuits and external capacitors, thereby reducing BOM cost and board area, and saving IoT device manufacturing costs.


The RX23W is now available in a 7mm x 7mm 56-pin QFN package and a 5.5mm x 5.5mm 85-pin GBA package with 512 KB of on-chip flash. The 56-pin QFN package with 512KB of on-chip flash is priced at $3.83 per 10,000-piece order.


(Note 1) The RX23W includes the RXv2 core, which achieves a high performance of 4.33 Coremark/MHz. CoreMark is a benchmark designed by EEMBC (Embedded Microprocessor Benchmark Consortium) to evaluate the performance of CPU cores. It is a set of programs written in C language that perform operations such as data reading and writing, integer computation and control. The performance value per operating frequency is a fraction of a run using the CC-RX V3 RX Series C/C++ Compiler.

(Note 2) FPU (Floating Point Unit): A functional unit dedicated to performing floating point calculations.
