ST and Qualcomm collaborating on sensors

Author: EIS Release Date: Nov 30, 2020


ST is supplying sensor software  through the Qualcomm Platform Solutions Ecosystem program.
ST is contributing pre-validated software to OEMs for its MEMS and other sensing devices to deliver features to smartphones, connected PCs, IoT, and wearables.
Qualcomm Technologies has pre-selected ST’s latest motion-tracking IC with intelligent sensor software, along with ST’s most accurate pressure sensor, for use in its latest advanced 5G mobile reference platforms.

The motion-tracking sensor, the iNEMO LSM6DST is a 6-axis Inertial Measurement Unit (IMU) that integrates a 3-axis digital accelerometer and a 3-axis gyroscope into a compact and efficient System-in-Package.
With 0.55mA power consumption in high-performance mode and 4mA in Accelerometer-only mode — the LSM6DST enables always-on  motion tracking with minimal impact on power consumption.
In concert with ST’s low-noise (0.65Pa), high-accuracy (±0.5hPa), and I3C-enabled LPS22HH pressure sensor, the pair provides location tracking while meeting restrictive power budgets.
For imaging applications, the LSM6DST fully supports EIS and OIS (Electronic and Optical Image Stabilization) applications as the module includes a dedicated configurable signal processing path for OIS and auxiliary SPI, configurable for both the gyroscope and accelerometer and, in turn, the Auxiliary SPI and primary interface (SPI / I²C & MIPI I3CSM) can configure the OIS.
Using ST’s ThELMA process technology, the LSM6DST supports and simplifies integration in low-power circuit designs and offers I²C, MIPI I3C or SPI from the sensing element to the application.
It also contains a 9-kbyte FIFO to allow dynamic data batching and 16 finite state machines that recognize programmed data sequences from the sensor and further reduce system-level power consumption.
