SCH1633-D01 (Murata 6-axis MEMS IMU, SCH1600 series) | Automotive-grade 6-degree-of-freedom (6DoF) inertial measurement unit

I. Core Hardware Specifications

Package: 24-pin SOIC, dimensions 12 × 14 × 3 mm

Power supply: VDD 3.0~3.6V; I/O 1.7~3.6V

Gyroscope range: ±62.5 / ±125 / ±300 °/s

Acceleration: ±8g (dynamic maximum ±26g)

Key precision highlights: Typical gyroscope bias instability at 0.4°/h, angle random walk at 0.03°/√Hz, and excellent temperature drift performance.

Interface: SafeSPI 2.0 (Secure SPI), 20-bit high-precision output; Built-in timestamps and SYNC synchronization signals facilitate time alignment of multiple sensors across the entire vehicle.

Diagnosis: Built-in 200+ internal monitoring signals, comprehensive self-diagnosis, meeting functional safety requirements.

Temperature: -40°C ~ +110°C

Orthogonal axis calibration is performed at the factory, so no additional cross-axis calibration is required on the customer's PCB side, significantly reducing production line costs. Murata Man...

II. Application Product List (Client-Side)

✅Mainstream Vehicle Scenarios (Advanced ADAS / Autonomous Driving Domain)

Domain Controller (Autonomous Driving Central Domain/Perception Domain ECU): The vehicle's central IMU, providing time synchronization and orientation reference for cameras, radars, and LiDARs; When GNSS is lost, high-precision dead reckoning (DR) is performed, and positioning is maintained in tunnels and urban canyons. This represents the largest market for the SCH1633-D01.

ADAS ECU: Front-facing/circular perception controller for vehicle posture, pitch and roll detection, camera distortion compensation, and radar point cloud coordinate transformation.

The vehicle headlight automatic leveling system continuously monitors the vehicle's pitch angle and dynamically adjusts the headlight height.

High-precision positioning box (integrated navigation unit: GNSS + IMU), a vehicle-grade integrated navigation module designed for autonomous driving in passenger vehicles and commercial vehicles.

The HUD (Head-Up Display) compensates for the vehicle's body posture and corrects the projected image.
