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
Application Examples
Medical Diagnostics
Infusion Pumps
Blood Pressure Monitors
Pressure Catheter Applications
Patient Monitoring
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). Front side die and wire protection
must be provided in the customer’s housing. Use caution when handling the devices
during all processes.

Freescale Semiconductor’s MPX2300DT1/
MPX2301DT1 Pressure Sensors have been designed for
medical usage by combining the performance of Freescale
Semiconductor’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 elasto-
mer 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 speci-
fied 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 per-
formance of the sensor. The MPX2301DT1 is a reduced gel
option.
Preferred devices are Freescale Semiconductor recommended choices for future use and best overall value.

NOTES:
1. Measured at 6.0 Vdc excitation for 100 mmHg pressure differential. VFSS and FSS are like terms representing the algebraic difference
between full scale output and zero pressure offset.
2. Maximum deviation from end--point straight line fit at 0 and 200 mmHg.
3. Slope of end--point straight line fit to full scale span at 15°C and +40°C relative to +25°C.
4. Slope of end--point straight line fit to zero pressure offset at 15°C and +40°C relative to +25°C.
5. For a 0 to 300 mmHg pressure step change.
6. Stability is defined as the maximum difference in output at any pressure within POP and temperature within +10°C to +85°C after:
a. 1000 temperature cycles, --40°C to +125°C.
b. 1.5 million pressure cycles, 0 to 300 mmHg.
7. Recommended voltage supply: 6 V ± 0.2 V, regulated. Sensor output is ratiometric to the voltage supply. Supply voltages above +10 V may
induce additional error due to device self--heating.
8. Offset measurement with respect to the measured sensitivity when a 150k ohm resistor is connected to VS and S+ output.
9. Accuracy is calculated using the following equation:
Errorp = {[Vp -- Offset)/(SensNom*VEX)]--P}/P
Where: Vp = Actual output voltage at pressure P in microvolts (µV)
Offset = Voltage output at P = 0mmHg in microvolts (µV)
SensNom = Nominal sensitivity = 5.01 µV/V/mmHg
VEX = Excitation voltage
P = Pressure applied to the device
