Product details
Overview
MPX4100AP1 from Freescale Semiconductor is a monolithic, signal-conditioned silicon absolute pressure sensor designed for manifold absolute pressure (MAP) sensing in internal combustion engine control systems. It delivers a ratiometric analog output (0.3–4.9 V) over a 20–105 kPa range, with ±1.8% full-scale accuracy from 0°C to 85°C, and operates from a 4.85–5.35 V supply. Its integrated temperature compensation and calibration enable direct microcontroller interfacing without external signal conditioning.
For engineers reviewing the MPX4100AP1 datasheet, MPX4100AP1 pinout, MPX4100AP1 application, or MPX4100AP1 equivalent, this device is selected for high-reliability automotive intake manifold pressure measurement where stable offset, fast 1 ms response time, and media-resistant packaging are critical design requirements.
Technical Context
The MPX4100AP1 implements a piezoresistive transducer element with on-chip bipolar signal conditioning, including two-stage gain amplification and thin-film temperature compensation circuitry. Its transfer function is VOUT = VS × (0.01059 × P − 0.1518), ratiometric to supply voltage.
It features a sealed vacuum reference cavity for absolute pressure measurement, fluorosilicone gel isolation of the die, and a durable epoxy unibody package (Case 867B-04) with a ported configuration for direct hose or tube connection to the intake manifold. The device is qualified for operation from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–105 kPa (2.9–15.2 psi); covers full operational vacuum-to-boost range of naturally aspirated and moderately boosted gasoline engines. |
| Output Voltage | 0.3–4.9 V at VS = 5.1 V; ratiometric scaling ensures consistent A/D conversion resolution across supply variations. |
| Accuracy | ±1.8% VFSS over 0–85°C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 1.0 ms (10%–90%); enables real-time cylinder-by-cylinder fuel calculation in high-RPM engine control. |
| Supply Voltage | 4.85–5.35 V DC; compatible with standard automotive 5 V regulator rails and tolerant of battery voltage fluctuations. |
| Operating Temp | −40°C to +125°C ambient; supports under-hood placement without external thermal shielding. |
| Max Pressure Limit | 400 kPa burst rating; provides robust safety margin against transient overpressure events in turbocharged applications. |
Pinout & Package
MPX4100AP1 uses the Case 867B-04 unibody surface-mount package - a durable epoxy housing with integrated stainless-steel port for direct manifold connection. Dimensions: 10.54 × 10.54 × 5.84 mm (L × W × H). Pin 1 is marked on the top surface adjacent to the port side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output signal (0.3–4.9 V); connects directly to MCU ADC input with minimal filtering (470 pF recommended). |
| 2 | GND | Analog ground reference; must be connected to low-noise system ground plane, separate from digital return paths. |
| 3 | VS | Positive supply input (4.85–5.35 V); requires 1.0 μF + 0.01 μF decoupling per Freescale AN1646 recommendations. |
| 4, 5, 6 | No Connect | Internally unused; left floating or grounded per layout best practices - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip signal conditioning | Eliminates need for external op-amps, ADC reference buffers, or temperature compensation circuitry - reduces BOM count by ≥4 components. |
| Fluorosilicone gel isolation | Protects silicon die from hydrocarbon vapors, oil mist, and condensation in engine bay environments while transmitting pressure accurately. |
| Ported (AP) mechanical interface | Integrated stainless-steel port enables direct, leak-tight hose connection - no adapter fittings or O-rings required for MAP hose routing. |
| −40°C to +125°C operation | Rated for under-hood mounting near throttle body or intake plenum without heat-sink or airflow dependency. |
| 0.5% VFSS offset stability | Guarantees long-term zero-point drift remains within ±0.5% after 1000 hours of pulsed pressure/temperature cycling - supports 15-year vehicle life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX4250AP | Wider 20–250 kPa range; same 867B-04 package and pinout; higher full-scale output (0.3–4.9 V still applies but scaled to 250 kPa). | Suitable for turbocharged or diesel engines requiring extended boost range; not drop-in for naturally aspirated MAP use due to reduced resolution below 105 kPa. | Select MPX4250AP only if system maximum pressure exceeds 105 kPa; otherwise MPX4100AP1 delivers superior signal-to-noise ratio in its native range. |
| SPX3115-001 | 3.3 V supply, I²C digital output; 15–115 kPa range; ±1.5% accuracy; SOIC-8 package with different footprint and pin assignment. | Requires MCU with I²C interface and firmware support for register reads; eliminates analog noise susceptibility but adds software overhead. | Choose SPX3115-001 when digital interface, lower supply voltage, or tighter accuracy is prioritized over analog simplicity and legacy ECU compatibility. |
Compared with MPX4250AP and SPX3115-001, the MPX4100AP1 offers optimal balance of analog simplicity, under-hood ruggedness, and resolution-matched performance for naturally aspirated gasoline engine MAP sensing - requiring no firmware changes or PCB redesign.

FAQ
What is the pressure reference type of the MPX4100AP1?
The MPX4100AP1 is an absolute pressure sensor with an internal sealed vacuum reference cavity. It measures pressure relative to absolute zero (perfect vacuum), not atmospheric or differential pressure. This makes it ideal for manifold absolute pressure (MAP) applications where intake vacuum must be quantified independently of ambient barometric variation. The MPX4100AP1 achieves this using a micromachined silicon diaphragm bonded to a vacuum cavity, ensuring stable zero-point calibration across temperature and lifetime.
Does the MPX4100AP1 require external signal conditioning?
No, the MPX4100AP1 does not require external signal conditioning. It integrates a complete signal chain: piezoresistive sensing element, temperature-compensation network, two-stage amplifier, and calibrated output buffer. The MPX4100AP1 delivers a fully conditioned 0.3–4.9 V ratiometric analog output directly compatible with standard 5 V microcontroller ADC inputs. Only basic power supply decoupling (1.0 μF + 0.01 μF) and optional output filtering (470 pF) are recommended per Freescale Application Note AN1646.
What is the meaning of "AP" in MPX4100AP1?
The "AP" suffix in MPX4100AP1 denotes the Ported mechanical configuration (Case 867B-04), distinguishing it from the base MPX4100A (Case 867-08, unported) and MPX4100AS (Case 867E-03, stove-pipe port). The AP variant features an integrated stainless-steel pressure port on the package underside, enabling direct hose or tube connection to the engine intake manifold without adapters. This simplifies mechanical integration and improves sealing reliability in automotive applications.
Can the MPX4100AP1 be used with a 3.3 V supply?
No, the MPX4100AP1 is not rated for 3.3 V operation. Its specified supply voltage range is 4.85–5.35 V DC, with nominal 5.1 V. Operation below 4.85 V risks output saturation, reduced accuracy, and failure to meet the ±1.8% VFSS specification. The MPX4100AP1's internal circuitry - including bandgap reference and amplifier stages - is optimized for 5 V rail operation. For 3.3 V systems, consider alternatives like the SPX3115-001 or MPXV5004DP, which are explicitly characterized at 3.3 V.
Is the MPX4100AP1 RoHS compliant and lead-free?
Yes, the MPX4100AP1 is RoHS compliant and lead-free. As documented in Freescale's Product Change Notices (PCN) and packaging specifications for Case 867B-04, the device meets EU Directive 2011/65/EU (RoHS 2) requirements. The epoxy unibody package, lead frame, and internal metallization are all lead-free, and the fluorosilicone gel conforms to halogen-free and REACH SVHC criteria. Full compliance documentation is available via NXP's official product page for MPX4100AP1.
