LUA600A is an automotive grade high-performance inertial measurement unit based on Murata’s SCHA634 chip. It consists of X-,Y- and Z-axis angular rate sensors and an integrated 3-axis accelerometer using Murata’s proven capacitive 3D-MEMS technology. The module is strictly factory calibrated, eliminating the need for separate calibration in the application. Parameters for gyroscope and accelerometer, such as offset drift over temperature, orthogonality error, and sensitivity, are trimmed during production. This ensures the consistency of module performance, allowing it to provide continuous, stable and accurate sensor measurement values across a wide temperature range.

Compared to the complexity of discrete designs, LUA600A offers a simple and cost-effective solution for integrating a high-performance IMU into industrial and automotive systems. Calibration procedure is completed during module production, streamlining the user integration process. The module utilizes a connector connection scheme, which minimizes the impact of temperature changes on the measurement of angular velocity and acceleration. Furthermore, the scheme effectively reduces the influence of PCB stress and isolates the heat conduction between the IMU sensing unit and the target board, in contrast to the board-mounted scheme. The module supports various communication interfaces such as UART, SPI and CAN, providing users with more options for debugging, development and solution creation. In addition, the module’s built-in MCU greatly increases the flexibility of software-related development functions to better meets user needs.
