May 4, 2015, Seoul, Korea — Freescale Semiconductor (www.freescale.co.kr, CEO Yeonho Hwang) has successfully completed its Tire Pressure Monitoring System (TPMS) portfolio with the announcement of the FXTH8715 product family for trucks and heavy vehicles. This product boasts the industry's smallest integrated package and the highest accuracy.

This ultra-compact solution consists of a 2-axis accelerometer, motion sensor, RF transmitter, LF receiver, pressure and temperature sensors, and a microcontroller, all contained within a 7 x 7mm package. In addition to exceptional accuracy, the solution can collect and transmit pressure, temperature, and acceleration values. This enables sophisticated analysis that can improve safe vehicle management and transform tire pressure sensing systems into end nodes that add future value.

The accuracy of the FXTH8715 product family is the highest in the industry (FXTH8715: +/-17kPa, competitor: +/- 23kPa) and the measurement pressure range is also the widest. (FXTH8715: 100-1500kPa, Competitor: 100-1300kPa)

"High-performance tire pressure sensing solutions capable of wireless communication offer significant benefits to trucks and heavy-duty vehicles regarding driver safety, fuel efficiency, stability, tire wear, and advanced warning prediction," said Babak Taheri, General Manager of Freescale's Sensor Solutions business unit. "Freescale's new FXTH8715 family can take tire pressure monitoring to a new level by capturing and transmitting useful sensor data that helps transport managers monitor tire pressure, track driver behavior, and optimize proactive maintenance. The combination of these capabilities enables transport companies to optimize vehicle usage and reduce downtime."

The integrated MCU and dedicated firmware of the FXTH8715 system support up to 8KB of flash memory, expanding application flexibility, shortening time-to-market, and supporting rolling encryption for more secure solutions.

"Thanks to the high accuracy, optimized integration, and small package size offered by the Freescale TPMS portfolio, we can provide users with the most reliable, robust, and accurate TPMS sensor technology on the market, as well as offer customers the industry's most comprehensive tire performance information," said Jeromy Mogharbel, Head of Engineering at PressurePro. "With this information, customers can identify and correct tire issues before they become dangerous or costly due to reduced tire life, and can also reduce downtime, maintenance time, and fuel consumption." "This information provides customers with the data necessary to identify performance trends and shift tire maintenance methods from reactive to proactive, which is a key factor in changing market trends," he said.
