Renesas Electronics (China) Co., Ltd. (“Renesas Electronics”), a subsidiary of Renesas Electronics Corporation, a leading global semiconductor solution provider, announced five new products, including the R7F0C205L, R7F0C206L, R7F0C206M, R7F0C207M and R7F0C208M, Expands its 16-bit microcontroller (MCU) product line to further enhance development support for touch-enabled home appliances, smart buildings, industrial automation and portable device applications. Embedded developers can take advantage of new products that integrate both user interfaces (including capacitive touch keys, LEDs and LCDs) and system control functions on a single chip.
The new MCU inherits the RL78 family of industry-leading low-power and superior electromagnetic compatibility (EMC) and other powerful performance. Developers of capacitive touch applications can utilize the state-of-the-art second-generation capacitive touch technology from Renesas Electronics at very low power and at very low cost. In addition, the embedded LCD and LED direct drive capabilities, support for a wide range of product designs, and regulate the developer MCU platform throughout the product line. The MCU also integrates high-current ports for driving LEDs and LCDs to optimize capacitive touch key applications with LEDs and LCD displays. The new MCU is Renesas Electronics’ first 16-bit touch MCU that supports LCD and LED direct drivers on a single chip. Delivered with a solution that includes MCUs, Workbench and Graphical User Interface (GUI) tools (HMI Code Generator), the new evaluation board and evaluation kit will be provided separately.
The main features of the new capacitive touch MCU:
Detect up to 64 keys, low-capacitance touch key standby current, high-current port directly drives the LED
The new MCUs support complex user interface requirements and support up to 64 keys. Helps to reduce the complexity of wiring when adding a touch panel, simplifies board design, and mutual-sensing key configuration improves waterproof performance. The average power consumption of capacitive touch keys in standby mode is only 6 microamperes (uA), effectively supporting battery-powered and other portable devices with low power requirements.
The built-in high current drive port of the MCU can directly drive the LED and is suitable for most LED display and touch button control LED display applications. The MCU also supports most common interfaces.
Workbench, software, and application notes are available to further reduce development time
The Workbench Auto-Alignment Tool, which is configured on the Renesas capacitive touch key MCU, makes it easier and faster to use the graphical user interface (GUI) to adjust to the effects of different board layouts, tracking patterns, panel materials, and more in the past Difficult to change the sensitivity and other settings. Combining the software and information needed for development, including application notes, user manuals, and reference software, Workbench can be used with MCU samples and evaluation boards to quickly confirm and evaluate system operations, reducing development time.
The capacitive touch R7F0C208M evaluation kit is IEC61000 certified
Three capacitive touch R7F0C208M evaluation kits have passed IEC 61000-4-3 and IEC61000-4-6 anti-noise certification and will be available soon.
Availability
New solutions and optional reference boards and evaluation boards will be available in February 2018.
The new MCU includes a 64-pin, 80-pin LQFP package and 48 KB to 128 KB flash memory for consumer and industrial applications. Its industrial-grade products support complex human-machine interface (HMI) designs in industrial applications.
