Description

The SP40T provides a very high level of integration, and is optimized to perform all of the functions necessary to

implement a state-of-the-art Tire Pressure Monitoring System (TPMS) sensor module. With its integrated micro

controller, sensors, and convenient peripherals, the SP40T needs the addition of only a few passive components

and a battery to form a complete TPMS sensor assembly.
