6 axis MEMS to manage GPS discontinuities in cars
ST microelectronics has launched a six axis MEMS device in a 3 x 3x1 mm package for automotive electronics. This mems device can help the GPS navigation system inside the car to continue to provide GPS information even if the signal from the GNSS satellite is not available temporarily. If the vehicle is going inside a tunnel or in a inside-building parking-lot or someplace where GPS signal is not available, the mems devices take the coordinate references from the lost connected GPS and provide the driver with the GPS data undisturbed.
ST microelectronics says 6-axis ASM330LXH is the industry’s smallest 6-axis Inertial Measurement Unit (IMU) qualified for Automotive applications with low-noise and improved output resolution.
6-axis ASM330LXH, empower sophisticated Dead Reckoning software algorithms that calculate current position from a previously determined location updated by time, acceleration, and change of direction. The new device also targets on-board units for electronic road tolling and other vehicle telematics systems.
“Having built its 8” MEMS manufacturing line in 2006 and introduced the world’s first automotive-qualified 3-axis MEMS gyroscope for non-safety applications in 2012, ST is fortifying its market leadership with the introduction of this 6-axis IMU that is accurate and reliable despite its small size,” said Anton Hofmeister, STMicroelectronics Group Vice President and General Manager Custom MEMS Division.
According to IHS, the market for automotive MEMS devices increased 13% last year, indicating sensor penetration rates that continue to grow faster than the growth of passenger vehicles.
AEC-Q100 qualified for automotive non-safety applications, the ASM330LXH is a robust sensor [up to 10000g shock survivability] that operates over an extended industrial temperature range (-40°C to +85°C). Electromagnetic reliability is assured through ST’s extensive solid design and packaging expertise.
Engineering samples of the ASM330LXH are available now, with volume production planned for Q1 2015 and unit pricing at $6 for orders of 1,000 pieces.
