MMA7455 3-Axis Accelerometer Module (#28526)
General Description
The Freescale Semiconductor MMA7455L 3-Axis Digital Output Accelerometer is a low power, micro-machined sensor capable of measuring acceleration along its X, Y, and Z axes. It offers several convenient integrated features including an analog to digital converter (ADC), digital low-pass filter, and selectable sensitivity ranges of ±2g, ±4g, or ±8g. This device can be easily configured to detect quick motion pulses as single-taps, double-taps, and 0g (free-fall) conditions on any or all axes and provides configurable interrupt pins (INT1 and INT2) for each type of event. Flexibility and compatibility are designed into this module. An on-board voltage
regulator and I/O voltage level-shifters make this module especially easy to connect to virtually any microcontroller. It operates over a wide range of supply voltages from 2.5 VDC to 5.5 VDC and communicates via Serial Peripheral Interface (SPI) or Inter-Integrated Circuit (I2C) bus.
Features
Wide input voltage range Digital output (SPI/I2C) Selectable sensitivity: 8-bit mode (±2g/±4g/±8g) or 10-bit mode (±8g) User-configurable interrupts (INT1/INT2) User-settable registers for calibrating each axis Low current operation Compact, 8-pin DIP breadbo...
