Overview
The IIS2DLPC is an ultra-low-power high-performance three-axis linear accelerometer produced by STMicroelectronics. It features a digital I²C/SPI output interface and leverages robust and mature manufacturing processes used for micromachined accelerometers. This accelerometer is designed to offer user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, with output data rates ranging from 1.6 Hz to 1600 Hz. It operates in multiple modes, including one high-performance mode and four low-power modes, which can be reconfigured on the fly to meet various application requirements. The device includes a 32-level FIFO buffer, embedded temperature sensor, and self-test capability, making it highly versatile and reliable.
