Freescale Semiconductor has announced that it is providing advanced acceleration sensor technology to Fujitsu. Fujitsu is using Freescale accelerometers to help protect business-critical data stored on hard disks in mobile PCs.
According to Freescale, its three-axis, low-g MMA7341L acceleration sensor helps safeguard data stored on hard disks (HDDs) used in Fujitsu’s FMV BIBLO LOOX R series PCs. The LOOX R series PCs are designed to store data on HDDs for a variety of business needs in various locations. Users of business laptop PCs regard HDD data protection to be a vitally important function.
When used in HDD designs, the MMA7341L sensor is designed to quickly detect an abnormal condition, such as a freefall, and retract the magnetic heads used for data read/write operation. This capability helps to protect data by preventing the HDD disk surface from being damaged, said Freescale.
The MMA7341L sensor also features plus/minus 2mg/degree for 0g offset voltage and 0.0075%/degree for sensitivity. Freescale integrates its acceleration sensors, which are widely used in automotive applications such as tire pressure monitoring systems, into small plastic packages to enhance reliability and help reduce overall system cost, added Freescale.
Kazuhiro Igarashi, corporate vice president of personal systems business unit at Fujitsu, said: The LOOX R series mobile PCs are designed to satisfy consumer demand for lightweight, low-power and robust laptops. We believe that Freescale’s acceleration sensors, which have proven to provide reliable solutions in automotive designs, will enhance the development of data protection features in our laptop products, now and in the future.
