ICM-42605

ICM-42605 is a 6-axis MotionTracking IMU from TDK InvenSense in a 14-pin LGA (2.5 x 3 x 0.91 mm) — for consumer motion sensing in wearables, IoT nodes, remote controls and compact robotics, and listed by TDK as Production. The selection point is the low-power, I3C-ready combination: gyroscope full-scale ranges of ±15.625 to ±2000 dps and accelerometer ranges of ±2/4/8/16 g, with gyroscope noise of 3.8 mdps/√Hz and accelerometer noise of 70 µg/√Hz, 6-axis low-noise current of 0.65 mA and a 2 KB FIFO to batch host wake-ups. Interfaces are I3C at 12.5 MHz, I2C or SPI at 24 MHz, on VDD/VDDIO rails of 1.71–3.6 V, with 20,000 g shock tolerance across −40 °C to +85 °C. Selection advice: the ICM-42605 is the consumer-temperature member of this platform — its industrial sibling IIM-42652 matches the full-scale ranges and noise class but extends operation to +105 °C, so fix the temperature requirement first, because the two codes serve different qualification envelopes. Against the higher-performance ICM-42688-P, this code trades peak performance for lower current, which is the right exchange in always-on consumer designs. Parameters verified against TDK InvenSense documentation.
