GENERAL DESCRIPTION
The IIM-20670 is a SmartIndustrialâ„¢ 6-axis
MotionTracking device that combines a 3-axis gyroscope
and a 3-axis accelerometer in a small plastic package. By
leveraging its patented and volume-proven CMOS-MEMS
fabrication platform, InvenSense has driven the package
size down to a footprint and thickness of 4.5x4.5x1.1
mm
3
(24-pin DQFN), to offer fully integrated, high
performance component in a compact form factor.
The IIM-20670 features:
• Six independent mechanical structures
• Gyroscope with programmable full scale range
from ±41 dps to ±1966 dps
• Accelerometer with programmable full-scale
range from ±2g, to ±65g
• Two temperature sensors
• 10 MHz Serial Peripheral Interface (SPI)
• 10,000 g shock tolerant structure
• Low offset and sensitivity variation over
temperature
IIM-20670 includes on-chip 16-bit ADCs, programmable
digital filters, and an embedded temperature sensor. The
device features an operating voltage range from 5.5V
down to 3.0V, and a current consumption below 10 mA
in all the operating conditions.
