MCUs Optimise HMI Design With Licence-Free GUI Software


Helping software engineers to create any kind of HMIs efficiently for their applications, Renesas announced that SEGGER’s powerful emWin GUI software package is now available for commercial use at no cost to customers using the new lineup of RX65N/RX651 microcontrollers (MCUs).

Engineers that develop a human-machine interface (HMI), or any commercial system based on an RX65N/RX651 device will receive a free license to use the emWin library version, including its full suite of tools.

The emWin embedded GUI software is compatible with single-task and multitask environments using a proprietary operating system, or with any commercial RTOS such as SEGGER’s embOS.

Designed for ultra-low power consumption, embOS can be used in any battery-powered application. Applications of emWin can be found in all market segments, including industrial, medical, consumer, smart home, white goods, and automotive.


The RX65N/RX651 MCUs combine an enhanced RX CPU core architecture and 120 MHz operation to achieve processing performance of 4.55 CoreMark/MHz.

The MCUs include an integrated Trusted Secure IP, enhanced, trusted flash functionality, and an HMI for industrial and network control systems operating at the edge of the Industrial Internet of Things (IIoT).

The RX65N/RX651 MCUs also include an embedded TFT controller and integrated 2D graphic accelerator with advanced features ideal for TFT displays designed into IIoT edge devices or system control applications.

“This emWin agreement with SEGGER gives our RX65N/RX651 MCU customers a powerful and flexible GUI software to ensure their HMI design is optimized with no extra software investment,” said Tim Burgess, Senior Director, Renesas Electronics Corporation.
