Freescale Semiconductor Technical Data Integrated Silicon Pressure Sensor Manifold Absolute Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and Calibrated The MPX4250A/MPXA4250A series Manifold Absolute Pressure MAP sensor for engine control is designed to sense absolute air pressure within the intake manifold. This measurement can be used to compute the amount of fuel required for each cylinder. The MPX4250A/MPXA4250A series piezoresistive transducer is a state-ofthe-art monolithic silicon pressure sensor designed for a wide range of applications, particularly those employing a microcontroller or microprocessor with A/D inputs. This transducer combines advanced micromachining techniques, thin-film metallization and bipolar processing to provide an accurate, high-level analog output signal that is proportional to the applied pressure. The small form factor and high reliability of on-chip integration make the Freescale sensor a logical and economical choice for the automotive system engineer. • Maximum Error Over 0° to 85°C • Specifically Designed for Intake Manifold Absolute Pressure Sensing in Engine Control Systems • Patented Silicon Shear Stress Strain Gauge • Temperature Compensated Over -40° to +125°C • Offers Reduction in Weight and Volume Compared to Existing Hybrid Modules • Durable Epoxy Unibody Element or Thermoplastic Small Outline, Surface Mount Package • Ideal for Non-Automotive Applications • Turbo Boost Engine Control • Ideally Suited for Microprocessor or Microcontroller-Based Systems ORDERING INFORMATION Device Type Options Case No. MPX Series Order Number SMALL OUTLINE PACKAGE 1 MPXA4250A SERIES Basic Absolute, Element Only Elements 482 MPXA4250A6U 482 MPXA4250A6T1 Ported Absolute, Axial Port Elements 482A MPXA4250AC6U MPXA4250AC6T1 UNIBODY PACKAGE 2 MPX4250A SERIES Basic Absolute, Element Only Element 867 MPX4250A Ported Absolute, Ported Elements 867B MPX4250AP Packing Options Device Marking Rails Tape & Reel Rails Tape & Reel MPXA4250A MPX4250A MPX4250AP The MPXA4250A series pressure sensors are available in the basic element package or with pressure port fitting.
