The ADXL345BCCZ from Analog Devices is a 3-axis digital MEMS accelerometer in a 14-lead LGA (5 x 3 x 1mm) package. It measures acceleration up to \u00b116g with 13-bit (4mg\/LSB) resolution, supporting user-selectable ranges (\u00b12g\/\u00b14g\/\u00b18g\/\u00b116g). Featuring SPI and I2C digital interfaces, ultra-low 23\u00b5A measurement current, 32-level FIFO buffer, and built-in activity\/inactivity, tap, and free-fall detection with flexible interrupt mapping, it operates from 2.0V to 3.6V and withstands 10,000g shock.<\/p>\n

Measuring up to \u00b116g with 13-bit (4mg\/LSB) resolution, it supports user-selectable ranges, SPI and I2C interfaces, and ultra-low 23\u00b5A measurement current. Built-in 32-level FIFO, activity\/inactivity detection, tap sensing, and free-fall detection with flexible interrupt mapping minimize host processor load. Operating from 2.0V to 3.6V with 10,000g shock survival, it is ideal for mobile devices, gaming, HDD protection, and medical instruments.","working_principle":"The ADXL345BCCZ uses a polysilicon surface-micromachined MEMS sensor structure built on top of a CMOS signal conditioning ASIC. Each axis has a differential capacitor structure where a proof mass suspended by polysilicon springs moves relative to fixed plates under acceleration. This displacement changes the differential capacitance, which is measured by the on-chip synchronous demodulator circuit. The demodulated signal is amplified, digitized by a 13-bit ADC, and corrected using factory-calibrated offset and sensitivity coefficients stored in on-chip non-volatile memory. In full-resolution mode, the 4mg\/LSB scale factor is maintained across all g-range settings, with resolution increasing from 10 bits at \u00b12g to 13 bits at \u00b116g. The digital output is formatted as 16-bit twos complement and accessed via SPI or I2C. The 32-level FIFO can buffer up to 32 x 3-axis samples, reducing host polling frequency and system power consumption. The embedded motion detection engines compare acceleration magnitudes against programmable thresholds to generate activity\/inactivity, tap, and free-fall interrupts without host processor intervention.","pin_description":"\n
