IAM-20680

High-Performance Automotive 6-Axis MotionTracking® Device

NOTE: We recommend using the IAM-20680HT as a replacement for this product.

The IAM-20680 is a 6-axis MotionTracking device for automotive applications; it combines a 3-axis gyroscope, and a 3-axis accelerometer in a small, 3 × 3 × 0.75 mm (16-pin LGA) package. It features a 512-byte FIFO that can lower the traffic on the serial bus interface, and reduces power consumption by allowing the system processor to burst read sensor data and then enter a low-power mode. The IAM-20680, 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, ±500, ±1000, and ±2000 degrees/sec. The accelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated 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 1.71 to 3.45V, and a separate digital IO supply, VDDIO from 1.71V to 3.45V.

Communication with all registers of the device is performed using either I²C at 400kHz or SPI at 8MHz.

By leveraging its patented and volume-proven CMOS-MEMS fabrication platform, InvenSense has driven the package size down to a footprint with a thickness of 0.75 mm to provide a very small yet high-performing package at a low cost. The device provides high robustness by supporting 10,000g shock reliability.
