Renesas RE Family Chosen as Main Controller of G-SHOCK Watch


RE Controller’s High-Performance and Ultra-Low Power Realized by SOTB Technology Enable Multifunctionality and Easy Use

Renesas Electronics Corporation announced that Casio Computer Co., Ltd. (“Casio”) has adopted a Renesas ultra-low power consumption RE Family controller as the main controller of the new Casio G-SHOCK watch GBD-H1000 with heart rate monitor and GPS functionality, unveiled on February 26, 2020.

The GBD-H1000 is a new addition to Casio's G-SHOCK line of shock-resistant watches that is equipped with: an optical sensor that measures heart rate by detecting changes in the blood flow under the skin; a triple sensor that measures compass bearing, barometric pressure/altitude, and temperature; and an acceleration sensor that measures step count and distance traveled, in addition to GPS functionality that acquires location information. The Renesas ultra-low power RE Family controller implements high-load internal watch processing while consuming very little power. This makes it possible to build user-friendly watches that offer an array of functions while requiring only solar power for charging during daily use.

The RE Family controller employed in the new watch utilizes Renesas’ exclusive SOTB™ process technology to achieve industry-leading ultra-low power consumption levels in both operating and sleep modes. Renesas and Casio worked together from the development stage of the GBD-H1000 watch onward to achieve both multifunctionality and low power consumption.

Moving forward, Renesas will continue to focus on the development of ultra low-power consumption controllers built around SOTB technology to help realize a smart society prioritizing human prosperity and the environment.
