IAM-20685 Automotive 6-axis MotionTracking® MEMS Device for ADAS and Autonomous Driving Applications
■The IAM-20685 is a 6-axis MotionTracking® device that combines a 3-axis gyroscope and a 3-axis accelerometer in a small plastic package with wettable flanks option.
■The IAM-20685 features:
▲Six independent axes
▲Gyroscope with programmable full scale range from ±41 dps to ±1966 dps
▲Accelerometer with programmable full-scale range from ±2 g, to ±65 g
▲Minimal cross-axis sensitivity between the accelerometer and gyroscope axes
▲MEMS structure hermetically sealed and bonded at wafer level
▲10,000 g shock tolerant structure
▲Two temperature sensors
▲10 MHz, 32-bits Serial Peripheral Interface (SPI) with CRC-based error-detecting code algorithm
▲ISO-26262 ASIL B
▲Automotive-qualified
▲Reliability testing performed according to AEC – Q100 grade 2 (-40°C to 105°C) qualification
▲Final test at three temperatures: -40°C, 25°C, 105°C
■IAM-20685 includes on-chip 16-bit ADCs, programmable digital filters, and embedded seft-test. The device features a VDD operating range of 3.0V to 5.5V, a separate digital IO supply, VDDIO, from 3.0V to 5.5V, and a current consumption below 10 mA in all the operating conditions.
■The IAM-20685 has been developed according to ISO-26262 with an automotive safety integrity level ASIL-B. Fault detection over lifetime is achieved by a set of embedded safety mechanisms (SMs) executed either at startup, upon command, or run-time.
■By leveraging its patented and volume-proven CMOSMEMS fabrication platform, which integrates Micro Electro-Mechanical Systems (MEMS) wafers with companion CMOS electronics through wafer-level bonding, TDK InvenSense has driven the package size down to a footprint and thickness of 4.5x4.5x1.1 mm³ (24- pin DQFN), to offer fully integrated, high performance component in a very small form factor.
