5 / 17 page Sensors Freescale Semiconductor 5 MPXY8000 An analog to digital (A/D) conversion can be accomplished with eight (8) different threshold levels in a successive approximation algorithm; or the OUT pin can be set to trip at some alarm level. The voltage on the sample capacitor will maintain long enough for a single 8-bit conversion, but may need to be refreshed with a new measured reading if the read interval is longer than the specified hold time, tSH. The counter that determines the number of clock pulses into the device is reset whenever the device is placed into the Measure Pressure or Measure Temperature Modes. This provides a means to reset the data transfer count in case the clock stream is corrupted during a transmission. In these two modes the DATA and CLK pins should not be clocked to reduce noise in the captured pressure or temperature data. Any change in the DAR contents should be done during the Standby or Output Read Modes. Both the serial bit counter and the state of the DAR are undefined following power up of the device. The serial bit counter can be reset by cycling either the SO pin or the S1/VPP pin to a high level and then back low. The DAR can then be reset to the lowest level by holding the DATA pin low while bursting the CLK pin with eight (8) clock pulses. Figure 5. Serial Data Timing Pressure Sensor Output The pressure channel compares the output of its analog measurement circuit to the D/A reference voltage. The device is calibrated at two different nominal values depending on the calibration option. Temperature Sensor Output The temperature channel compares the output of a positive temperature coefficient (PTC) resistor driven by a switched current source. The current source is only active when the temperature channel is selected. APPLICATIONS Suggested application example is shown in Figure 6. Figure 6.
