Micropower, 3-Axis, ±2 g/±4 g/±8 g Digital Output MEMS Accelerometer

Product Details

The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.

The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 1 mg/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 μg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 μg/√Hz typical) can be selected at minimal increase in supply current.

In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.

The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm × 3.25 mm × 1.06 mm package.

EVAL-ADXL362Z Circuit Diagram

Product Details

Use for integration of the ADXL362 into an existing system. 

The EVAL-ADXL362Z is a simple breakout board that enables easy connection of an ADXL362 micropower, 3-axis, digital-output MEMS accelerometer into an existing system. Due to its small size, the EVAL-ADXL362Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL362 in an existing system. Note that the ADXL362 must be communicated with digitally via SPI. No processor is included with the EVAL-ADXL362Z; firmware must be supplied externally by the user. Some sample firmware is available in the Software and Tools section below.


EVAL-ADXL362Z-MLP Circuit Diagram

Product Details

Use for real-time evaluation, parameter testing, and general familiarization with the ADXL362.

The EVAL-ADXL362Z-MLP is a complete system for real-time evaluation of the ADXL362 micropower, 3-axis, digital-ouptut MEMS accelerometer. This system is accompanied by a graphical user interface (GUI) that facilitates evaluation of parameters such as power consumption, temperature coefficient, noise, and more. The system consists of a motherboard and a satellite board. The sensor is housed in a socket on the satellite board, enabling evaluation of multiple parts using one evaluation system.

To order the complete system, order the EVAL-ADXL362Z-MLP. This kit includes a motherboard, satellite board, accelerometer, and cables. Additional satellite board kits can be ordered using the part number EVAL-ADXL362Z-S. Satellite kit orders include a satellite board and an accelerometer.

Product Details

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


EVAL-WSN Circuit Diagram

Product Details

The Wireless Sensor Network (WSN) demo platform is a flexible, modular system for evaluating all aspects of a WSN. It offers both an out-of-the-box demonstration system, and can also be used as a development platform. It contains all of the hardware and software necessary to implement a plug-and-play WSN.  The hardware includes a base station node along with multiple sensor nodes that support many different sensors. The system is flexible in that sensors can be connected in any combination to any of the sensor nodes. The out-of-the-box utility of the WSN development kits significantly reduces the time and effort required to move a customer’s design from proof-of-concept phase to production release through the marriage of three Multi-Sensor Node Boards, a gateway connector, an emulator platform, and a full featured software package.
