Pressure Freescale Semiconductor MPX2300DT1 Rev 7, 10/2008 High Volume Pressure Sensor for Disposable Applications Freescale Semiconductor has developed a low cost, high volume, miniature pressure sensor package which is ideal as a sub-module component or a disposable unit. The unique concept of the Chip Pak allows great flexibility in system design while allowing an economic solution for the designer. This new chip carrier package uses Freescale Semiconductor's unique sensor die with its piezoresistive technology, along with the added feature of on-chip, thin-film temperature compensation and calibration. NOTE:Freescale Semiconductor is also offering the Chip Pak package in application-specific configurations, which will have an “SPX” prefix, followed by a four-digit number, unique to the specific customer Features • • • • • Low Cost Integrated Temperature Compensation and Calibration Ratiometric to Supply Voltage Polysulfone Case Material (Medical, Class V Approved) Provided in Easy-to-Use Tape and Reel MPX2300DT1 MPX2301DT1 Pressure Sensors 0 to 300 mmHG (0 to 40 kPa) Application Examples • • • • • Medical Diagnostics Infusion Pumps Blood Pressure Monitors Pressure Catheter Applications Patient Monitoring ORDERING INFORMATION Device Name MPX2300DT1 MPX2301DT1 Package Options Tape and Reel Tape and Reel Case No. 423A 423A Gauge Pressure Type Differential • • Absolute Device Marking Date Code, Lot ID Date Code, Lot ID CHIP PAK PACKAGE MPX2300DT1/MPX2301DT1 CASE 423A-03 NOTE: The die and wire bonds are exposed on the front side of the Chip Pak (pressure is applied to the backside of the device).

Pressure The MPX2300DT1/MPX2301DT1 Pressure Sensors have been designed for medical usage by combining the performance of Freescale's shear stress pressure sensor design and the use of biomedically approved materials. Materials with a proven history in medical situations have been chosen to provide a sensor that can be used with confidence in applications, such as invasive blood pressure monitoring. It can be sterilized using ethylene oxide. The portions of the pressure sensor that are required to be biomedically approved are the rigid housing and the gel coating. The rigid housing is molded from a white, medical grade polysulfone that has passed extensive biological testing including: tissue culture test, rabbit implant, hemolysis, intracutaneous test in rabbits, and system toxicity, USP. A silicone dielectric gel covers the silicon piezoresistive sensing element. The gel is a nontoxic, nonallergenic elastomer system which meets all USP XX Biological Testing Class V requirements. The properties of the gel allow it to transmit pressure uniformly to the diaphragm surface, while isolating the internal electrical connections from the corrosive effects of fluids, such as saline solution. The gel provides electrical isolation sufficient to withstand defibrillation testing, as specified in the proposed Association for the Advancement of Medical Instrumentation (AAMI) Standard for blood pressure transducers. A biomedically approved opaque filler in the gel prevents bright operating room lights from affecting the performance of the sensor. The MPX2301DT1 is a reduced gel option.
