Tire Pressure Sensors with Acceleration and Integrated Pressure

The Infineon SP3x (SP30/35) family of TPMS pressure sensors combines a silicon micro-machined pressure and acceleration sensor as well as a temperature sensor in a specific ASIC.
This ASIC also integrates a micro controller for signal-conditioning of the sensing data and for generation of the data protocol which will be transmitted via an external UHF transmitter (e.g. TDK5100 or TDK5101). The device is provided in a small-foot-print DSO14 package.
