Tronics, a MEMS foundry and device maker, introduced this week a new high performance MEMS based angular rate sensor (gyro) for applications such as platform stabilization. The product is based on Tronics' MEMS-on-SOI and high vacuum wafer level packaging technologies. Tronics has been active in the design and manufacture of high performance MEMS gyros for more than 10 years. According to the company, the product aimed at a segment of the gyro market that is currently under-served and typically does not warrant custom development.
"This product launch is an interesting step for Tronics as it is the first gyrometer in a product line which could contribute significantly to our revenue in the coming years. Tronics will continue to focus on custom MEMS design and manufacturing projects; however, we will increasingly leverage our experience and launch new standard products for selected growing MEMS markets," explained Tronics' CEO Peter Pfluger.
Tronics said that its new MEMS gyro is designed for applications in industrial, aerospace, and military markets, which require much higher performance than automotive, without being as demanding as "tactical grade" applications. It is the first in a family of gyros that Tronics intends to position at the forefront of MEMS based gyro performance.
This product, Tronics said, is the result of years of development experience, not only on the MEMS transducer, but also on the ASIC drive and control circuits, as well as the gyro package. Tronics also benefits from its experience in manufacturing SOI based inertial devices operating under high vacuum at the wafer level.
Tronics said that it has manufactured and delivered more than a million high performance inertial devices and is a recognized expert in this field.
The new MEMS gyro features good bias instability (Allen variance) of 1 degree per hour, a noise density of 10°/h/Sqrt(Hz), and thermal bias stability of +/- 0.05 degrees per second. This single Z-axis device is small (0.55 cm3), lightweight (2.6 grams), and has a 24-bit output.
The product is manufactured in Grenoble, where Tronics has front-end, back-end, test and calibration capacity to serve this high-end market.
The new MEMS gyro was already sampled to several key customers in the last few months. It was officially introduced at the Electronica tradeshow this week, and will be commercially available in the first quarter of 2013.
Tronics is an international MEMS manufacturer with wafer fabs in Europe and the United States. The company's engineering support includes electronic interface development, assembly and custom packaging. Tronics has manufactured MEMS products such as accelerometers, gyros, and pressure sensors, as well as actuators such as pumps, switches and mirrors.
