Integrated on-board 5V to 3.3V chip for 5V power supply microcontroller system. The MMA7455L is mounted on a small printed circuit board (PCB).
MMA745 is a digital output (I2C/SPI), low power consumption and compact capacitive micromachined accelerometer with signal conditioning, a low-pass filter, temperature compensation, and self-test. It can be configured with the interrupt pin (INT1 or INT2), detect 0g, and has pulse detection. 0g offset and sensitivity are factory-configured and require no external components. Customers can use the specified 0g registers and g-Select range selection bias against 0g. Set calibration range can be selected by command to three acceleration range (2g/4g/8g). MMA745xL series has a standby mode, making it for battery-powered handheld electronic devices an ideal choice.
