ADXL345BCCZ-RL7

Overview

The ADXL345BCCZ-RL7 is a small, thin, ultralow power 3-axis accelerometer featuring high-resolution measurement up to 13 bits at +/-16g. It provides digital output formatted as 16-bit twos complement data, accessible through either an I2C or SPI digital interface. The device is designed to measure both dynamic acceleration from motion or shock and static acceleration such as gravity, making it suitable for tilt-sensing applications.

Why Choose This Part

This accelerometer excels in power-constrained designs due to its sub-30uA run current and dedicated sleep modes. The integrated FIFO buffer and hardware-level motion detection features, such as tap and free-fall detection, reduce the computational burden on the host microcontroller. Its wide supply voltage range of 2V to 3.6V ensures compatibility with most modern low-voltage embedded systems.

Applications

Getting Started

For rapid prototyping, engineers often use the ADXL345 with the EVAL-ADXL345Z evaluation board. The device communicates via standard I2C or SPI; ensure the CS pin is pulled high for I2C mode or low for SPI mode. Developers can utilize the manufacturer's C-based driver libraries to configure the data rate and G-select registers.
