概述

Description

ICM-20608D is a 6‑axis MEMS IMU from InvenSense (now part of TDK). It combines a 3‑axis accelerometer and a 3‑axis gyroscope with an on‑chip digital motion processor (DMP) for on‑board sensor fusion.
Key points:
- Interfaces: I2C or SPI
- Output: high data rates (up to ~1 kHz) with FIFO buffering
- Full-scale ranges: accelerometer typically ±2/4/8/16 g; gyroscope ±125/250/500/1000/2000 dps
- Power modes: configurable for low power
- Extras: temperature sensor, self‑test, interrupt outputs
- Applications: drones, robotics, wearables, motion sensing in devices
Note: exact pinout, register map, and DMP options vary by revision; consult the official datasheet and reference software for implementation details.

Features

Key features of the ICM-20608D:
- 6‑axis IMU: 3‑axis accelerometer + 3‑axis gyroscope.
- 16‑bit sensor data with programmable full scales: accelerometer ±2/4/8/16 g; gyroscope ±125/250/500/1000/2000 dps.
- High ODR with configurable digital filtering (up to 1 kHz data rate; configurable LPF).
- On‑chip temperature sensor for bias/temperature compensation.
- FIFO buffer and multiple interrupt options (data ready, FIFO watermark, etc.) for efficient data handling.
- Flexible serial interfaces: I2C and SPI (standard voltage compatibility).
- Low-power operation with sleep and accelerometer‑only modes.
- Self‑test and factory calibration for drift reduction.
- Small form factor (LGA package) and wide operating conditions: −40 °C to 85 °C.

Package

ICM-20608D is packaged in a 3×3 mm QFN (24-pin) package.

Pinout

ICM-20608D pin count: 28-pin LGA package.
Main pin functions (grouped):
