Renesas Electronics’ first products in the company’s new Renesas Synergy Platform include the S7G2 and S3A7 microcontroller (MCU) groups, which target connected human machine interface (HMI) and power-efficient control applications used in industrial, healthcare, home appliance and metering products. Development kits featuring the two MCU groups, software development tools, and the Renesas Synergy Software Package (SSP) are available now from the Renesas Synergy Gallery.
The company’s Synergy Platform is designed to accelerate time to market, reduce total cost of ownership and remove many of the obstacles engineers face when designing Internet of Things (IoT) and other embedded applications.
The S7G2 and S3A7 are the first MCUs in the Renesas Synergy Platform, and the first scalable MCUs in the industry to be optimized for software development. By supporting an API that gives designers direct access to a completely integrated real-time operating system (RTOS) with communication stacks, middleware, libraries, an application framework and the MCUs’ drivers and peripherals, the Renesas Synergy Platform eliminates the design work needed to enable the essential system functions so designers can quickly begin development of their own application software.
MCUs from the Renesas Synergy S7G2 group feature a 240MHz ARM Cortex-M4 CPU core and high capacity 4 Megabyte flash to accommodate the software needs of HMI applications today and in the future. MCUs from the Renesas Synergy S3A7 group incorporate a 48MHz ARM Cortex-M4 CPU to deliver a hardware solution well suited for HMI applications requiring power efficient operation. The S7G2 and S3A7 MCUs are pin and peripheral compatible so software developed for one MCU group can be used with the other. Future Renesas Synergy MCUs will also support this compatibility feature.
To facilitate the design of HMI applications, the S7G2 and S3A7 MCUs integrate support in silicon to utilize touchscreen LCD displays, including a capacitive touch sensing unit and a highly configurable LCD color graphics controller (S7G2) and segment LCD controller (S3A7). Design kits for both MCUs are now available with many enabling features. The DK-S7G2 kit has a detachable 4.3-inch WQVGA color LCD touch display plus a VGA camera, and the DK-S3A7 kit has a detachable custom segment LCD display and extensions for deep evaluation of Renesas’ third-generation capacitive touch technology. The kits have a variety of connectivity options including USB-HS and USB-FS, Dual Ethernet, CAN, and a Bluetooth low energy 4.0 radio. A very low-cost starter kit, the SK-S7G2, is also available for S7G2 MCUs that opens complete access to the entire Synergy Platform and all of its software capabilities for well under US$100, enabling development of color graphics, high-speed connectivity, and multi-media functions. Beyond standard development kits, the first product example (PE) is available for S7G2 MCUs that provide engineers and developers a complete example of an HMI end-product implementation. The PE-HMI1 includes a detailed document that captures how it was developed, giving engineers a step-by-step journey through the design choices made to build the solution so they can reproduce or alter the design themselves for their own end-products.
