tire pressure monitoring sensor 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 motorolas ssop (super small outline package) package. the ssops 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 series consists of four devices, listed below, which are defined by pressure ranges for vehicles from small cars to trucks. mpxy8000 series tire pressure monitoring sensor features ? pressure and temperature sensor, and interface circuit with wake-up feature, all on a single chip ? automotive grade tem- perature specification (-40c to +125c) ? pressure ranges avail- able from 0 to 1275 kpa ? 4c temperature sensor accuracy over entire application range ? digital (8-bit) serial protocol interface (spi) output for both temper- ature and pressure sensor ? ratiometric to supply voltage, from 2.1v to 3.6v ? ssop package offering robust media protection and small footprint ? 3 second wake-up for module level energy management ? on-chip power manage- ment via separate operating modes, fast response times, and low current draw.

ssop physical dimensions tire pressure monitor system 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: ? mpxy80xx - pressure and temperature sensor, and interface circuit ? 68hc908rf2 - mcu+rf transmitter housed in a single package ? mc33591 - rf receiver ? mc9s12dp256 - microprocessor 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). tire pressure monitoring system enabling chip set remote sensing module (rsm) pressure sensor temperature sensor power control wake up timer mpxy8020a6 pll uhf trans hc08 2k flash lv rc osc/ ext osc timer low volt detect ram mc68hc908rf2 + - 3v battery rke mc68hc908rf2 bat rke & tpms receiver mc33591 + mc9s12dp256
