GENERAL DESCRIPTION

The ADXL343 is a versatile 3-axis, digital-output, low g MEMS accelerometer. Selectable measurement range and bandwidth, and configurable, built-in motion detection make it suitable for sensing acceleration in a wide variety of applications. Robustness to 10,000 g of shock and a wide temperature range (?40°C to +85°C) enable use of the accelerometer even in harsh environments.

FEATURES

Multipurpose accelerometer with 10- to 13-bit resolution for

use in a wide variety of applications

Digital output accessible via SPI (3- and 4-wire) and I2C

Built-in motion detection features make tap, double-tap,

activity, inactivity, and free-fall detection trivial

User-adjustable thresholds

Interrupts independently mappable to two interrupt pins

Low power operation down to 23 μA and embedded FIFO for

reducing overall system power

Wide supply voltage range: 2.0 V to 3.6 V

I/O voltage 1.7 V to VS

Wide operating temperature range (?40°C to +85°C)

10,000 g shock survival

Small, thin, Pb free, RoHS compliant 3 mm × 5 mm × 1 mm

LGA package

APPLICATIONS

Handsets

Gaming and pointing devices

Hard disk drive (HDD) protection
