Renesas Synergy™ Microcontrollers

A high-quality product needs to be built on a high-quality foundation. With a wide range of performance and features, Renesas Synergy™ microcontrollers (MCUs) can meet the scalability, power consumption, and performance needs of nearly any end-product using embedded system control. Designed for the rapidly expanding IoT market, Renesas Synergy™ MCUs have features built-in to ease connectivity, establish rock-solid security, ensure dependable safety and create human-machine interfaces.


Renesas has developed four series of MCUs for use in end-products ranging from small mobile devices to larger, high performance calculation intensive applications. The Renesas Synergy™ MCUs in each series are all part of the same family and are feature and pin compatible, allowing easy scalability and code reuse from one device to another.


Renesas Synergy™ Microcontroller Portfolio

The four MCU series in the Renesas Synergy™ family include:

High Performance

Core Frequency
200-300 MHz

Blazing fast processor core plus secure connectivity and industry-leading large memory sizes opens up developers' design options for connected IoT applications, breaking through limitations previously faced by developers and engineering teams.

High Integration

Core Frequency
100-200 MHz

A secure connectivity suite, large memory and serial memory expansion, high-accuracy analog, TFTLCD graphics with 2D engine and many built-in safety functions make S5 Series MCUs ready for extremely capable embedded control applications across the board.

High Efficiency

Core Frequency
32-100 MHz

Enhanced CPU processing power, secure connectivity, advanced analog and timing control, safety self-test features, segment LCD and capacitive touch control, all built on a very low power silicon process are prime ingredients for smart IoT sensors and localized control.

Ultra-Low Power

Core Frequency
Up to 32 MHz

Ultra-low power MCUs enable incredibly long battery life in portable or non-portable applications that must survive a long time in standby mode. The S1 Series MCUs allow that without sacrificing analog capabilities, secure connectivity, or robust safety.

Scalability and Compatibility

Renesas Synergy™ MCUs scale up and down in memory size and in function across the entire portfolio with pin-to-pin compatibility. This means drop-in pin-to-pin compatibility for similar packages within a given MCU series and extremely similar pin compatibility across similar packages over different MCU series. Since Renesas Synergy™ MCUs were designed from the start with pin compatibility in mind, it is even possible to create circuit board layouts with multiple package footprints within each other (a smaller package footprint inside a larger package footprint) for flexible manufacturing options of your end-product.


Peripheral compatibility is also a reality across the entire Renesas Synergy™ MCU portfolio meaning that a given peripheral (a UART or a timer for example) has the same baseline functions in all the MCUs series, but the peripherals scale upward in function for higher MCUs. Software developed for one MCU series has high re-use on other series MCUs. Develop once, use multiple times. This also simplifies maintenance, documentation, and ultimately saves time.


The example below demonstrates how various grades of home and commercial security panels can be scalable and take advantage of Renesas Synergy™ MCU compatibility.
