MPXY8021A: Tire Pressure Monitor Sensor

The block diagram of the MPXY8021A Sensor is shown in Figure 1. The Pressure Sensor is a capacitive transducer constructed using surface micromachining, the Temperature Sensor is constructed using a diffused resistor, and the Interface circuit is integrated onto the same die as the Sensors using a standard silicon CMOS process.
