Renesas Delivers Industry’s Most Complete Intelligent Sensor Solutions for IoT Applications

Offers New Sensors and Signal Conditioning ICs Complementing Leading MCU Line, Advanced Firmware, Embedded AI, and Unique Quick-Connect IoT Design Platform

TOKYO, June 22, 2022 ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, is changing the way designers build sensor-connected IoT applications with a range of new solutions targeted at faster design cycles, improved accuracy, and reduced system cost.

In addition to the new HS4XXX family of relative humidity and temperature sensors, Renesas is introducing the ZSSC3281 sensor signal conditioning (SSC) IC for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. These new products complement Renesas’ extensive MCU portfolio and embedded AI solutions.

The sensor design process is supported by Renesas’ unique system design platform that significantly eases the prototyping of IoT systems. The Renesas Quick-Connect IoT system consists of standardized boards and interfaces, enabling designers to quickly and easily connect a wide range of sensors to MCU/MPU development boards. The new system also delivers core software building blocks that are portable between boards, greatly reducing coding requirements. Now, instead of writing and testing hundreds of lines of driver code, designers only need to graphically select their sensor and write a few lines of code. All the integration and setup effort happen behind the scenes, reducing the time to a working solution.

Renesas also provides numerous Winning Combinations that combine sensors with multiple other ICs to offer customers an elevated design platform that mitigates the design risks and reduces development time.

According to a recent Zion Market Research study, the Global IoT sensors market is estimated to grow at a compound annual growth rate (CAGR) of approximately 27.9%, reaching an estimated $27.9 billion by the year 2028.

“Sensing solutions are a critical element in IoT systems, and present numerous design challenges during system integration that can slow development and impact overall system performance,” said DK Singh, Senior Director of the Systems and Solutions Team at Renesas. “The combination of our sensor technology, signal conditioning expertise, and system solution mindset enables us to deliver customers a design platform that is unmatched by any competitor.”

With more than 20 years’ experience, Renesas has deep and broad expertise in the sensor market. Renesas’ portfolio includes sensor signal conditioners, biosensors, humidity and temperature sensors, light and proximity sensors, flow sensors, and position sensors.
