Sensor inercial acelerometro 3 eixos - Rda217

(alternativo ao Bosch BMA253/421, Kionix1009/1057, mCube3413/3416)

The Rda217 sensor is ultra-low power high performance capacitive three-axis linear accelerometer developed by micro-machined technology.

The device is available in a 2x2x0.9mm land grid array (LGA) and it is guaranteed to operate over an extended temperature range from -40°C to+85°C.The sensor element is fabricated by single crystal silicon with DRIE process and is protected by hermetically sealed silicon cap from the
environment.

The device features user selectable full scale of ±2g/ ±4g/±8g/ ±16g measurement range with data output rate from 1Hz to 500Hz with signal condition,
temperature compensation, motion detection, step counter and step detection along with significant motion detection embedded. The Rda217 has an integrated 32-level first-in, firstout (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. Two independent and flexible interrupts provided greatly simplify the algorithm
for various motion status detections. Standard I2C and SPI interfaces are used to communicate with the chip.
