Freescale Introduces World's Thinnest 3-axis Accelerometer for Motion-Based User Interfaces.Low-Profile Smart MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. Sensor Offers Digital Output and Simplifies Controller Integration for Mobile Devices LYON, France -- Freescale Semiconductor Freescale Semiconductor, Inc. is an American semiconductor manufacturer. It was created by the divestiture of the Semiconductor Products Sector of Motorola in 2004. Freescale focuses their integrated circuit products on the automotive, embedded and communications markets. today expanded its micro-electromechanical systems (MEMS)-based sensor portfolio with a 3-axis digital-output accelerometer accelerometer Instrument that measures acceleration. Because it is difficult to measure acceleration directly, the device measures the force exerted by restraints placed on a reference mass to hold its position fixed in an accelerating body. that is 77 percent smaller than previous industry offerings. The world's thinnest accelerometer, the MMA (Microcomputer Managers Association, Inc.) A membership organization with chapters throughout the U.S. that was devoted to educating personnel responsible for personal computers. It disbanded in 1996. Mma - A fast Mathematica-like system, in Allegro CL by R. Fateman, 1991. 7450L is available in a 0.8 mm thin plastic land grid array The land grid array (LGA) is a type of surface-mount packaging used for integrated circuits. It can be electrically connected to a PCB either by the use of a socket or by soldering directly to the PCB. (LGA LGA abbr. large for gestational age LGA Large for gestational age, see there ) package designed to meet the growing space constraints of feature-rich portable devices. Designed to simplify integration of microprocessors and microcontrollers (MCUs), the MMA7450L is ideal for handheld terminals that implement user interfaces based on hand movements and appliances that require movement, acceleration or inclination sensing. "The potential of triple-axis accelerometers is sparking the imagination of designers for all kinds of end uses, which will drive the growth of MEMS sensors in portable consumer electronics by nearly 10 percent over the next five years," said Marlene Bourne Bourne, town (1990 pop. 16,064), Barnstable co., SE Mass., crossed by Cape Cod Canal; settled 1627, inc. 1884. Bourne Bridge (1935), across the canal, made the town an entry point to Cape Cod and a resort and commercial center. , principal analyst at Bourne Research. "Low profile is extremely important, and Freescale has set the bar with one of the thinnest packages yet." The MMA7450L can communicate on both I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller and SPI (1) (Stateful Packet Inspection) See stateful inspection. (2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. interface buses. The digital output streamlines communication with the MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users or microprocessor. It eliminates the need for a dedicated analog-to-digital converter and enables the sensor to share interfaces with other devices, saving further space in small-form-factor systems. Additionally, portable device manufacturers can connect the MMA7450L directly to a wireless platform, such as Freescale's i.MX architecture, or a highly integrated 8-bit MCU to design accelerometers into cell phones and portable media devices. The MMA7450L enables an array 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-percent 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." In addition to providing an on-board digital output, the MMA7450L embeds features, such as threshold and pulse or click-detect for quick motion detection and offset calibration, eliminating the need for external memory. The MMA7450L includes a g-select feature with three sensitivities (2g, 4g, 8g). This gives designers the flexibility to select the g-force detection level a specific application needs. The MMA7450L is an ideal solution for portable consumer electronics that require a fast response time, high sensitivity, low-current consumption, low-voltage operation and a standby mode in a small package. Leveraging its experience and heritage of zero-defect quality and reliability in the automotive market, Freescale continues to enhance its sensor designs, providing very high immunity to vibration and shock resistance up to 10,000g.
