What are the key features of LSM303C?

  • 3-axis accelerometer with ±2g/±4g/±8g selectable full-scale range and 16-bit resolution
  • 3-axis magnetometer with ±4/±8/±12/±16 gauss selectable full scale for compass heading
  • SPI and I2C dual digital interfaces up to 10 MHz SPI for fast data readout
  • Ultra-compact LGA-12 package measuring 2 mm × 2 mm × 1 mm for wearable integration
  • Embedded FIFO buffer for accelerometer data reducing host processor intervention
  • 2.16V to 3.6V supply voltage range compatible with low-power microcontroller systems

What is LSM303C used for?

The LSM303C is used in mobile and wearable applications requiring 6-axis motion sensing, including electronic compasses, step counters, activity monitors, and augmented-reality headsets where accurate tilt-compensated heading is essential. Its integrated accelerometer and magnetometer in a single 2 mm × 2 mm package reduces BOM count and simplifies PCB layout for smartwatches, fitness trackers, and drone navigation modules. The device also supports motion-triggered wake-up functions that minimize power consumption in always-on sensing scenarios.

Frequently Asked Questions

What full-scale ranges does the LSM303C accelerometer and magnetometer support?

The LSM303C accelerometer supports selectable full-scale ranges of ±2g, ±4g, and ±8g, while the magnetometer supports ±4, ±8, ±12, and ±16 gauss. Both sensors output 16-bit digital data, enabling fine resolution across these ranges. This flexibility allows engineers to tune sensitivity for applications ranging from gentle tilt detection to high-impact shock monitoring.

How does the LSM303C's LGA-12 package size compare to competing 6-axis eCompass modules?

The LSM303C occupies a 2 mm × 2 mm × 1 mm LGA-12 footprint, one of the smallest available for a combined accelerometer-magnetometer eCompass module. This enables placement in ultra-thin wearables, smart glasses, and compact drone autopilots where board space is under 4 mm² per sensor function, a significant advantage over older devices in larger 3 mm × 3 mm or 4 mm × 4 mm packages.

What supply voltage does the LSM303C require, and can it work directly with a 3.3V microcontroller?

The LSM303C operates from 2.16V to 3.6V, making it fully compatible with 3.3V microcontroller I/O without level shifters. The digital interface voltage (VDD_IO) can be set independently between 1.71V and 3.6V, supporting 1.8V logic systems found in modern low-power application processors and wireless SoCs.

Which navigation or motion-control designs gain the most from using the LSM303C's combined sensor approach?

Tilt-compensated electronic compass designs benefit most, since the LSM303C provides both the accelerometer data needed for tilt correction and the 3-axis magnetic field data for heading in a single device with one I2C address scheme. Drone autopilots, robotic orientation modules, and AR/VR handsets using 6-degree-of-freedom tracking also gain board-space and power efficiency by replacing two discrete sensors with this 2 mm × 2 mm combo IC.
