TPMS provides industry’s highest pressure accuracy

The ultra-compact system integrates a dual-axis accelerometer, motion sensor, RF transmitter, low frequency receiver, pressure and temperature sensor and an MCU into a 7x7mm package. In addition to its superior accuracy, the system’s onboard intelligence enables the collection and transmission of sensor data, including pressure, temperature and acceleration. This enables sophisticated analytics, which can improve fleet maintenance and transform tire pressure systems into value-added end-nodes for the IoT.

The pressure accuracy of FXTH8715 family products is the highest in the industry (±17kPa vs. nearest competitor at ±23kPa). The family’s products also feature the highest operating range in the industry (100-1500kPa vs. nearest competitor at 100-1300kPa). The integrated MCU and dedicated firmware support up to 8kB of flash memory, extending application flexibility, reducing time to market and supporting rolling encryption for a more secure solution.

Babak Taheri, Vice President and General Manager, Sensor Solutions Division, Freescale, comments: “Highly accurate tire pressure sensing solutions capable of communicating wirelessly offer tremendous advantages in terms of driver safety, fuel efficiency, reliability, tire wear and advance warning prognostication for trucks and heavy vehicles. Freescale’s FXTH8715 family takes tire pressure monitoring to new levels by capturing and transmitting valuable sensor data that helps fleet managers not only monitor tire pressure, but also track driving behaviour and optimise predictive maintenance. Together, these capabilities help fleets optimise vehicle usage and avoid downtime.”

The FXTH8715 TPMS family is available now for a suggested resale price from $5.40 in 10,000 unit quantities.
