TPMS (Tire Pressure Monitoring System) and how we can do it using Freescale's solution.

This webcast discussion will focus on Freescale's solution for Tire Pressure Monitoring System (TPMS). An introduction will be given to the concept of TPMS, what it is and why it is needed. Following this, Freescale's chipset solution will be presented with information coverage on the sensor IC (Daytona), RF IC, and the integrated MCU chip. Some technical tips will be given on the implementation of such a system and what needs to be considered for the mounting of the pressure sensor module. Also some insights relating to RF and software flow aspect will be briefly discussed.
