The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ?16g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.The ADXL345 is well suited for mobile device 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 (4 mg/LSB) enables measurement of inclination changes less than 1.0?.Several special sensing functions are provided. Activity and inactivitysensing detect the presence or lack of motion by comparingthe acceleration on any axis with user-set thresholds. Tap sensingdetects single and double taps in any direction. Free-fall sensingdetects if the device is falling. These functions can be mappedindividually to either of two interrupt output pins. An integratedmemory management system with a 32-level first in, first out (FIFO)buffer can be used to store data to minimize host processor activityand lower overall 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 ADXL345 is supplied in a small, thin, 3 mm ? 5 mm ? 1 mm, 14-lead, plastic package.

The ADXL362 Development Board is an easy-to-use tool designed to shorten application development time by enabling data collection and firmware development on an existing hardware platform. To highlight the ultralow power consumption offered by the ADXL362, the board is designed as a low-power platform. Communications and processing are performed by a Renesas RL78/G13 ultralow power microcontroller, and firmware is written in C. An e-paper display shows numeric or graphical output, depending on the firmware loaded. The board is fully programmable via USB, and a development environment and header files are available from Renesas. Schematics and layout are provided so that the platform can be duplicated in the final application, having already been tested with the application firmware. The board is pre-configured as a motion-activated on/off switch. Other firmware examples available are a tilt sensor, a datalogger, and a real-time data viewer (provided with a GUI that graphs real-time acceleration data on a computer screen). The board can be powered over USB, with a CR2450 coin cell battery, or from an external supply. Supplied with the board are the e-paper display, a USB cable, and a microSD card for logging data. Other evaluation tools available for the ADXL362 are the GUI-based real-time evaluation system, EVAL-ADXL362Z-MLP, and a simple Breakout Board, refer to the EVAL-ADXL362Z

The ADXRS620 is a complete angular rate sensor (gyroscope)that uses the Analog Devices, Inc. surface-micromachiningprocess to create a functionally complete and low cost angularrate sensor integrated with all required electronics on one chip.The manufacturing technique for this device is the same highvolume BiMOS process used for high reliability automotiveairbag accelerometers.The ADXRS620 is an automotive grade gyroscope that has 100% pin, package, temperature, and function compatible to the available industrial grade ADXRS652 gyro. Automotive grade gyroscopes have more extensive guaranteed min/max specifications due to automotive testing.The output signal, RATEOUT (1B, 2A), is a voltageproportional to angular rate about the axis normal to the topsurface of the package. The output is ratiometric with respect toa provided reference supply. A single external resistor can beused to lower the scale factor. An external capacitor sets thebandwidth. Other external capacitors are required for operation.A temperature output is provided for compensation techniques.Two digital self-test inputs electromechanically excite thesensor to test proper operation of both the sensor and the signalconditioning circuits. The ADXRS620 is available in a 7 mm ?7 mm ? 3 mm BGA ceramic package.APPLICATIONS Vehicle chassis rollover sensing Inertial measurement units Platform stabilization
