Freescale’s MPXY8300 tire pressure monitor system (TPMS) chipset is designed to enable a timely warning to the driver in the case of under-inflated or over-inflated tires on cars, trucks or buses—even while in motion. It is the first of its kind to offer capacitive sensor technology and full integration of a pressure sensor, an 8-bit S08 microcontroller (MCU), a radio frequency (RF) transmitter and an XZ-axis accelerometer in one package.
