GENERAL DESCRIPTION
The IAM-20680 is a 6-axis MotionTracking device for
Automotive applications that combines a 3-axis gyroscope, 3-
axis accelerometer, and FSYNC for image stabilization
functionality in a small 3x3x0.75mm (16-pin LGA) package.
• Large 4K-byte FIFO to reduce 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
• Gyroscope programmable FSR of ±250dps, ±500dps,
±1000dps and ±2000dps
• Accelerometer with Programmable FSR of ±2g, ±4g, ±8g
and ±16g
• EIS FSYNC support
• Tested to meet AEC-Q100 Grade 3 qualification
IAM-20680 includes on-chip 16-bit ADCs, programmable
digital filters, an embedded temperature sensor, and
programmable interrupts. The device features an operating
voltage range down to 1.71V. Communication ports include
I2C and high speed SPI at 8MHz.
