IAM-20680HP

IAM-20680HP High Performance Automotive 6-Axis MotionTracking Device GENERAL DESCRIPTION The IAM-20680HP is a 6-axis MotionTracking device for Automotive non-safety applications that combines a 3axis gyroscope and a 3-axis accelerometer in a small 3x3x0.75mm3 (16-pin LGA) package. It also features a 4096-byte FIFO that can lower the traffic on the serial bus interface and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode. IAM-20680HP, with its 6-axis integration, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance. The gyroscope has a programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps and ±2000 dps. The accelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factorycalibrated initial sensitivity of both sensors reduces production-line calibration requirements. Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The device features I2C and SPI serial interfaces, a VDD operating range of 1.71V to 3.6V, and a separate digital IO supply, VDDIO from 1.71V to 3.6V.
