The ICM-40627 is an ultra-low-power 6-axis MEMS inertial measurement unit (IMU) from TDK InvenSense, purpose-built for battery-constrained micro UAV applications. It combines a 3-axis gyroscope and a 3-axis accelerometer in a compact LGA-14 package (2.5×3.0×0.91mm). What distinguishes the ICM-40627 from other members of the ICM-4xxxx family is its dramatically reduced power consumption — drawing only 0.3 mA in 6-axis low-power mode and 1.2 mA at full performance, making it the ideal IMU choice for sub-250g micro drones, whoop-style FPV quadcopters, and long-endurance fixed-wing platforms where every milliampere matters.
The sensor's built-in Digital Motion Processor (DMP) is a key advantage for power-sensitive drone designs. By offloading sensor fusion algorithms from the main flight controller MCU (such as STM32F405 or AT32F435), the DMP allows the host processor to remain in low-power sleep mode for longer periods, further extending flight time. For Betaflight and INAV compatible flight controllers, the ICM-40627 provides clean gyro data at selectable output data rates up to 32 kHz, enabling responsive PID control even on resource-constrained microcontroller platforms.
With a gyroscope range of up to ±2000 dps and an accelerometer range of up to ±16 g, the ICM-40627 covers the full spectrum of UAV flight dynamics — from gentle fixed-wing cruise to aggressive acrobatic maneuvers in micro quadcopters. The 2 KB hardware FIFO buffer reduces bus traffic by allowing burst reads, which is particularly valuable in I²C-based designs where bus bandwidth is limited. Both SPI (up to 24 MHz) and I²C (up to 400 kHz) interfaces are supported, providing flexibility for different flight controller PCB layouts and microcontroller pin constraints.
The ICM-40627 is also well-suited as a secondary IMU for redundant attitude estimation in larger drone platforms. In a redundant IMU architecture, a low-power sensor like the ICM-40627 can run continuously at low sample rates to provide backup attitude data, while a higher-power primary IMU handles high-rate control loops. This dual-IMU approach is increasingly common in commercial and industrial UAVs where safety and reliability are paramount. The component operates reliably across the full industrial temperature range of −40°C to +85°C and accepts a wide supply voltage from 1.71V to 3.6V.
