MC3430

MC3430 3-Axis Accelerometer GENERAL DESCRIPTION FEATURES Preliminary Datasheet The MC3430 is a low-noise, integrated digital output 3-axis accelerometer with a feature set optimized for cell phones and consumer product motion sensing. Applications include user interface control, gaming motion input, electronic compass tilt compensation for cell phones, game controllers, remote controls and portable media products. Accurate event detection is enabled with a low noise architecture that minimizes false triggering found in competing devices. Low noise and low power are inherent in the monolithic fabrication approach, where the MEMS accelerometer is integrated in a single-chip with the electronics integrated circuit. The sample rate of the MC3430 can be programmed from 1 to 128 samples / second. Even greater power savings can be achieved by taking advantage of event detection while the device is in a low power mode. Specific orientation and gesture conditions can trigger an interrupt to...
