The ADXL313 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±4g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3-wire or 4-wire) or I2C digital interface.
The ADXL313 is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (1024 LSB/g) and low noise (150 μg/√Hz) enable resolution of inclination changes of as little as 0.1°. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025° of inclination.
Several built-in sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. These functions can be mapped to interrupt output pins. An integrated 32-level FIFO can be used to store data to minimize host processor intervention, resulting in reduced system power consumption.
Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
The ADXL313 is supplied in a small, thin 5 mm × 5 mm × 1.45 mm, 32-lead LFCSP package and is pin compatible with the ADXL312 accelerometer device.
APPLICATIONS
- Car alarms
- Hill start aid (HSA) systems

EVAL-ADXL313Z
ADXL313 Breakout Board
Product Detail
The EVAL-ADXL313Z is a simple breakout board that enables easy connection of an ADXL313 into an existing system. The ADXL313 is a digital-output, 3-axis accelerometer whose low power consumption and built-in features make it ideal for use in a wide variety of applications. Due to its small size, the EVAL-ADXL313Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL313 in an existing system. Note that the ADXL313 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL313Z; firmware must be supplied externally by the user. For evaluation boards that include a processor, please see the EVAL-ADXL313-SDP.

EVAL-ADXL313-SDP
Real Time Evaluation System Based on SDP-B Evaluation System
Product Detail
The EVAL-ADXL313-SDP is an easy-to-use Customer Evaluation System that allows the user a quick start on testing an evaluating the ADXL313 accelerometer. The system consists of a main board (EVAL-SDP-CB1Z evaluation platform), an interface board (EVAL-SDP-INTERZ), and a satellite board (EVAL-ADXL313Z breakout board).
The EVAL-SDP-CB1Z board, also called “SDP-B”, connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The SDP-B is connected to the interface board (EVAL-SDP-INTERZ), which provides the signal conditioning and electrical connections to communicated with the satellite board (EVAL-ADXL313Z) through a cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components.
The main and interface boards are compatible with the EVAL-ADXL312Z and EVAL-ADXL314Z breakout boards as well.
The EVAL-ADXL313-SDP Customer Evaluation System comes with all the necessary cables and connectors. Each part of this kit can be purchased separately.
