GENERAL DESCRIPTION
The ICG-20660/L is a 6-axis MotionTracking device that
combines a 3-axis gyroscope, 3-axis accelerometer, in a small
3x3x0.75 mm (16-pin LGA) package.
• High performance specs
o ICG-20660L: Gyroscope sensitivity error: ±1%
o Gyroscope noise: 6.5mdps/√Hz
• Includes 512-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
• EIS FSYNC support
The only difference between the 2 devices is the gyro initial
sensitivity where it is 1% on ICG-20660L and it is 3% on ICG-
20660.
The ICG-20660 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 1.71 V. Communication ports include
I
2
C and high speed SPI at 7 MHz.
