STMicroelectronics LSM6DSLTR LGA-14 6-Axis Accelerometer Gyro Sensor

The LSM6DSLTR operates from a single supply voltage (Vdd) ranging from 1.71V to 3.6V. This makes it compatible with both 3.3V and lower-voltage logic systems commonly found in modern microcontrollers and battery-powered devices.

The sensor supports both I2C (up to 1 MHz) and SPI (4-wire, up to 10 MHz) digital interfaces. The interface is selected via hardware pin (CS). For I2C, use the SDA and SCL pins with a 7-bit device address. For SPI, use the standard MOSI, MISO, SCLK, and CS pins. Refer to the datasheet for the detailed register map and communication protocol.

It includes several on-chip algorithms to reduce host processor load: a pedometer and step counter for activity tracking, motion detection for wake-up interrupts, free-fall detection for drop sensing, and tilt detection for orientation changes. These features are configurable through the device's control registers.

The integrated 4 kB FIFO (First-In, First-Out) buffer allows the sensor to batch data internally. This enables the host microcontroller to enter low-power sleep modes for extended periods while the sensor continues collecting data, significantly reducing overall system power consumption in always-on applications.
