Thinnest accelerometer claimed by Freescale
Aimed at enabling motion based functions in a range of space constrained portable consumer electronics devices, a three axis digital output MEMS based accelerometer from Freescale is said to be 77% smaller than previous industry offerings. At 0.8mm thick, the MMA7450L is also claimed as the world’s thinnest accelerometer.
The MMA7450L enables a range of motion based functions, such as tilt scrolling, gaming control, tap to mute and freefall hard disk drive protection. “This digital output accelerometer allows designers to make mobile devices – such as mobile phones and portable gaming – more advanced, enjoyable and easier to use,” Demetre Kondylis, vice president and general manager of Freescale’s sensor and actuator solutions division. “We have achieved a 77% reduction in package size and combined three axes of sensing direction with digital output, eliminating the need for an a/d converter and external memory. In short, this is an ideal acceleration sensor for the handheld consumer electronics market.”
The MMA7450L can communicate on both i²c and spi interface buses and its digital output streamlines communication with an mcu or microprocessor.
