Accelerometer takes CMOS interface
onboard
Robust three-axis MEMS sensor and CMOS interface chip combine to provide tilting and motion information, independent of the device's orientation.
STMicroelectronics has extended its family of ultracompact low-g linear accelerometers with a three-axis analogue-output sensor Ideally suited for battery-powered and space-constrained portable devices, such as mobile phones, portable media players, PDAs or remote controls, the LIS344AL is a cost-sensitive MEMS solution in an ultracompact square footprint operating with low power consumption

Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
Single-chip tuner cuts set-top box parts count
The STB6000 single-chip silicon tuner is designed to replace complex discrete component tuners in set-top boxes used for receiving digital TV or web-based material via satellite.
The single-package approach protects a robust three-axis MEMS sensor and a CMOS interface chip that provides tilting and motion information, independent of the device's orientation, thanks to the three-axis sensing capabilities.
The LIS344AL estimates acceleration values at a very low noise level with minimised power consumption, which is especially critical in battery-operated portable systems.
The new accelerometer is housed in an inexpensive 4 x 4 x 1.5mm plastic package to fit in a variety of space-constrained applications and its ultracompact, robust design provides shock survivability up to 10,000g.
ST's new accelerometer offers a full-scale output range of +/-3.5g.
The built-in self-test facility allows the user to verify both the mechanical and electrical parts of the device.
The accelerometer uses ST's Ecopack lead-free technology for RoHS compliance.
The LIS344AL addresses a wide range of applications including: data-integrity protection; user interface; antitheft systems; remote device controls; intelligent motion-based power management; and sport and health monitoring devices.
The LIS344AL is in volume production now.
Unit pricing is US $1.40 for large volumes.
