Freescale Rolls Out Tire Pressure Monitoring System Built on Industry-Leading Sensor Technology.Intelligent, Single-Package Chipset Helps Car Makers Meet Global Automotive Safety Requirements with Precise Tire Pressure Sensing TOKYO -- 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. , has introduced the industry's first tire pressure monitoring system A tire pressure monitoring system (TPMS) is an electronic system to monitor the air pressure inside a pneumatic tire. They are sometimes referred to as remote tire pressure monitoring systems (RTPMS) or simply as Run flat indicators. (TPMS (Transaction Processing Monitor System) A TP monitor from Fujitsu Services, formerly ICL, that is used in conjunction with its IDMSX database system. TPMS supports up to 16,000 online users. See IDMSX. ) containing a capacitive pressure sensor A pressure sensor measures the pressure, typically of gases or fluids. Pressure is an expression of the force required to stop a gas or fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor generates a signal related to the pressure imposed. for ultra-low power consumption and precise sensing. Freescale's MPXY8300 system-in-package device provides a highly integrated, cost-effective solution that combines an advanced pressure sensor with an 8-bit microcontroller (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 ), 2-axis 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. and radio frequency (RF). Freescale's MPXY8300 single-package solution is designed to address global motor vehicle safety requirements for accurate, timely tire pressure monitoring. Properly inflated tires can help reduce the potential for life-threatening blowouts, enhance road handling, improve fuel efficiency, prolong tire life and lower the cost of vehicle ownership. The National Highway Traffic Safety Administration The National Highway Traffic Safety Administration (NHTSA, often pronounced "nit-suh") is an agency of the Executive Branch of the U.S. Government, part of the Department of Transportation. (NHTSA NHTSA National Highway Traffic Safety Administration (US government) ) estimates that 23,000 accidents and more than 500 fatalities a year in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. involve flat tires and blowouts stemming from improperly inflated tires (over or under inflation). To help curb tire-related accidents in the U.S., NHTSA regulations require new vehicles weighing up to 10,000 pounds to include TPMS technology by model year 2008. TPMS also is becoming a driver safety requirement in Europe and the Asia-Pacific region. "While TPMS designs have been around for a few years, direct system cost and customer cost-of-ownership remain key concerns for vehicle makers," said Chris Webber For the Canadian-born former BBL basketball player, see . Mayce Edward Christopher Webber III, better known as Chris Webber or C-Webb (born March 1, 1973, in Detroit, Michigan), is an American professional basketball player for the Detroit Pistons of the NBA.. , vice president of Strategy Analytics' Automotive Practice. "To achieve improvements in both of these areas, automotive OEMs are looking for Looking for In the context of general equities, this describing a buy interest in which a dealer is asked to offer stock, often involving a capital commitment. Antithesis of in touch with. highly integrated TPMS solutions, such as Freescale's, that offer excellent low power management for longer battery life and high levels of integration for reduced system cost." Freescale's MPXY8300 TPMS solution is designed to help drivers maintain proper tire pressure by instantly notifying them when any individual tire (including the spare) is not at the optimal pressure level. Engineered for wheel-mounted applications, the highly integrated MPXY8300 system helps automotive engineers reduce development cycle time, component count and system cost by combining the necessary digital, analog and sensor functions of a TPMS in a single, compact package. In addition to being a leading supplier of 8-bit automotive MCUs, Freescale offers a wide range of high-performance analog, power management, pressure and inertial sensor, and RF devices for automotive applications. About the MPXY8300 TPMS solution Freescale's intelligent MPXY8300 system offers precise, real-time tire pressure measurement using direct monitoring at each wheel. Additionally, Freescale's single-package solution has an integrated accelerometer for motion detection. The system can be programmed to transmit measurements at certain tire rotation Tire rotation or rotating tires is the practice of moving automobile tires from one wheel to another to ensure even tire wear. Tire wear is uneven for any number of reasons. Even tire wear is desirable to maintain consistent performance in the vehicle. speeds and even when the tires are not rotating at all. The MPXY8300 system-in-package device features these key components: * Pressure and temperature sensors for compensating tire pressure * 8-bit MCU with 512b RAM, 16 KB flash * XZ-axis accelerometer * RF transmitter * Low-frequency input for receiving diagnostic commands The MPXY8300 incorporates a number of low-power techniques engineered to help extend TPMS battery life beyond 10-year requirements. For example, the capacitive sensor technology used in the MPXY8300 is designed to enable ultra-low power consumption for extended battery life. "Freescale's continued innovation in TPMS technology is enabling higher integration and greater functionality for enhanced driver safety and superior vehicle performance," said Paul Grimme, senior vice president and general manager of Freescale's Transportation & Standard Products Group. "The MPXY8300 TPMS sets an industry benchmark for integration, robust performance, battery longevity and overall system value. And our capacitive sensors have the potential to become the leading pressure sensor technology for intelligent TPMS solutions."
