Chinese foundry Hua Hong Semiconductor Limited is jointly developing a 3-axis gyroscope system-on-chip (SoC) with microelectromechanical systems (MEMS) vendor Shanghai Quality Sensor Technology Corp. (QST).
The MEMS device, dubbed the QMG6982, was developed using Hua Hong’s 200mm MEMS manufacturing process and features a MEMS gyroscope integrated into an application specific integrated circuit (ASIC) on a single chip.
This combination allows for a more compact design, with low power, high sensitivity and zero-drift stability, Hua Hong says. The MEMS SoC is targeted at smart devices such as smartphones, tablets, watches and other wearables as well as Internet of Things applications.
The manufacturing of the 3-axis gyroscope continues the partnership between Hua Hong and QST that included the launch of a magnetic and accelerator sensor.
According to Joseph Xie, president of QST, gyroscopes is one of the most technologically demanding products among motion sensors and is dominated by only a few global brands. With this gyroscope SoC, the Chinese companies are looking to compete with a product that will cater to engineers’ need for low-cost, high performance MEMS sensors as well as appeal to Chinese domestic vendors, he says.
