SP40PLUS Overview
The SP40PLUS 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 SP40PLUS needs the addition of only a few passive ponents and a battery to form a plete TPMS sensor assembly.
