Freescale Semiconductor expands its micro-electromechanical systems (MEMS)-based sensor portfolio with Model MMA7450L, a three-axis digital-output accelerometer. It is available in a 0.8 mm thin plastic land grid array (LGA) package that is designed to meet the space constraints of portable devices. Designed to simplify integration of microprocessors and microcontrollers, the device is suitable for handheld terminals that implement user interfaces based on hand movements and appliances that require movement, acceleration or inclination sensing. It can communicate on both I2C and SPI interface buses. The digital output streamlines communication with the MCU or microprocessor, eliminating the need for a dedicated analog-to-digital converter. This accelerometer enables motion-based functions such as tilt scrolling, gaming control, tap to mute and freefall hard disk drive protection.
