Motorola introduces the MPXY8000 series family of tire

pressure monitoring sensors that are comprised of a

capacitive pressure sensing element, a temperature-sensing

element, and an interface circuit with wake-up feature, all on

a single chip. This chip is housed in Motorola’s SSOP

(super small outline package) package. The SSOP’s size and

enhanced media protection make it the perfect package

solution for Tire Pressure Monitoring System (TPMS)

remote sensing modules, mounted on valve stems or wheel

wells.

The MPXY8000 series is compatible with Tire Pressure

Monitoring Systems using a Remote RF Sensing

approach, and is ideal for integration with existing Remote

Keyless Entry (RKE) systems. In addition, Motorola offers

a comprehensive chip set for a TPMS-RKE system that

eliminates the need for an additional TPM specific receiv-

er. This chip set is comprised of:

The features of this chipset enable a system to identify

individual tires (including the spare), as well as to detect

both "over-pressure" and "under-pressure" conditions.

The system also has the ability to compensate for changes

in cargo load, and monitor tire temperature. The module

level energy management features support extended

battery life, and signals a low battery condition. Further-

more the system is compatible across vehicle platforms

and tire technologies (run-flat tires).
