  • Hard drive protection

The ADXL343BCCZ-RL7 is a 3-axis digital accelerometer from Analog Devices with 13-bit resolution and selectable +/-2g to +/-16g ranges. Featuring both SPI and I2C interfaces, a 32-level FIFO buffer, and comprehensive motion detection features including activity/inactivity, free-fall, and tap detection, it provides complete motion sensing capability. The 40uA measurement current and tiny LGA package make it ideal for battery-powered portable devices.

The ADXL343 uses a polysilicon surface-micromachined capacitive sensing structure. Acceleration deflects a proof mass, changing the differential capacitance between fixed plates. An internal ADC converts this capacitance change to digital acceleration values. The 32-level FIFO stores up to 32 samples to reduce host processor polling frequency. Built-in state machines detect specific motion patterns (activity, free-fall, tap) and generate interrupts. The device supports both SPI and I2C for flexible system integration.
