The Renesas RE product family is used as the main controller in G-SHOCK watches with heart rate monitoring and GPS functions

Tokyo, Japan, March 18, 2020-Renesas Electronics Corporation (TSE: 6723), the world’s leading semiconductor solutions provider, today announced that Casio Computer Co., Ltd. (hereinafter referred to as “Casio”) has adopted Renesas ultra-low power consumption The RE product family controller serves as the main controller of the new Casio GBD-H1000 “G-SHOCK” watch. This product is equipped with heart rate monitoring and GPS functions and was released on February 26, 2020.

GBD-H1000 is the latest member of Casio’s G-SHOCK series of shock-resistant watches. It is equipped with: an optical sensor that measures heart rate by detecting changes in blood flow under the skin; a triple sensor that measures compass azimuth, atmospheric pressure/altitude and temperature ; GPS function that can obtain location information, and acceleration sensor that can measure the number of steps and distance traveled. Renesas’ ultra-low power RE product family controller achieves high-load processing capabilities inside the watch, while at the same time extremely low power consumption, helping to create user-friendly watch products. This watch can achieve multiple functions and only needs solar power for daily life.

The RE product family controller used in the new watch is based on Renesas’ unique SOTB process technology, achieving industry-leading ultra-low power consumption in both working and standby modes. Renesas and Casio started cooperation at the initial stage of the development of the GBD-H1000 watch, and jointly promoted the realization of the product’s multi-function and low power consumption.

Masuda Yuichi, Senior Executive Director of Casio, Senior General Manager of Product R&D Headquarters, and Senior General Manager of Watch Business Department of Business Strategy Headquarters, said: “The development of GBD-H1000 requires technological innovation to improve processing performance and exceed the linear expansion of previous processor capabilities. We chose Renesas’ SOTB technology based on its outstanding performance and power efficiency. I am very grateful to the Renesas RE product family for its great contribution to the improvement of the GBD-H1000 function.”

Keito Nitta, Senior Vice President of Renesas Electronics and SoC Business Leader of the Internet of Things and Infrastructure Division, said: “It is a great honor for Casio to adopt the Renesas RE product family as the main controller for its new G-SHOCK watch. Casio is committed to developing unprecedented innovations. The commitment and enthusiasm of the product left us a deep impression. I am very happy that we can break through the technical barriers and expand the various functions of G-SHOCK. I look forward to continuing to work with Casio to seek further technological innovation in the future and jointly develop new products. To enrich people’s lives.”

Looking forward to the future, Renesas will continue to focus on the research and development of ultra-low power controllers based on SOTB technology, and contribute to the construction of an intelligent society that focuses on human long-term prosperity and green environmental protection.
