Tri-Axial Accelerometer has serial digital output.
Press Release Summary:
Operating on 2.7-3.6 V, LIS3L02D includes single MEMS sensor chip and calibrated interface chip that senses changes in capacitance in sensor and translates them into SPI or I2C serial digital outputs. It has equivalent noise acceleration of better than 500 millionths of 1 g. Unit is suited for use in handheld terminals to implement motion-based user interfaces, allowing one-handed operation without styli, thumb keyboards, or other input devices.

STMicroelectronics Announces Three-Axis MEMS-based Accelerometer with Serial Digital Output
Combination of three-axis MEMS sensor and interface chip in single package targets mobile terminal applications
Visit ST at the 3GSM World Congress (Hall 4, Booth K21) in Cannes, February 23-26, 2004
Geneva, February 16, 2004 - STMicroelectronics (NYSE: STM) announced today that the company is sampling a MEMS-based three-axis accelerometer device that provides, for the first time, both three-axis sensing in a single package and a digital output. The device will be demonstrated on the ST booth at the 3GSM World Congress in Cannes, February 23-26, 2004.
Called LIS3L02D, the new device is designed primarily for handheld terminals where it can be used to implement new motion-based user interfaces based on hand movements, allowing one-handed operation without styli, thumb keyboards or other input devices. Other applications include toys, industrial equipment, robotics, automotive systems and appliances where sensing of movement, acceleration or inclination is needed.
The LIS3L02D includes a single-chip MEMS sensor chip plus a calibrated interface chip that senses changes in capacitance in the sensor and translates them into SPI or I2C serial digital outputs. Compared to assemblies of single-axis sensors the device is simpler, less expensive and more precise, cutting manufacturing costs.
An earlier version of the LIS3L02D has been selected as a finalist in the components category in EDN Magazine's 2003 Innovation of the Year Award. This program honors outstanding electronic products across the broad spectrum of original equipment manufacturing and test products.
Accelerometers based on silicon-micromachined MEMS technology exploit the changes in capacitance caused by the relative movement of moving and fixed structures created in the silicon, using wafer-processing techniques. STMicroelectronics offers a broad range of MEMS-based sensor devices, including linear sensors for one, two and three axes, plus rotational accelerometers. These devices are assembled with an interface chip that generates analog, PWM or serial digital outputs, factory-trimmed to ensure close tolerance without production line adjustment of the end product.
The LIS3L02D operates on a 2.7 to 3.6V supply voltage. The device has an equivalent noise acceleration of better than 500 millionths of one 'g'. During transport and service it can withstand accelerations up to 3000 g without damage, making it sufficiently shock resistant for mobile phone applications. Pricing in volume quantities begins at $5.00.
