Product details
Overview
MPXH6101AC6U from Freescale Semiconductor is a monolithic, signal-conditioned, absolute pressure sensor with 15–102 kPa range, ±1.72% full-scale error over 0 °C to 85 °C, and ratiometric 5 V supply operation. It delivers a high-level analog output (0.168–4.933 V) proportional to absolute intake manifold pressure and is engineered for direct integration into engine control units.
For engineers reviewing the MPXH6101AC6U datasheet, MPXH6101AC6U pinout, MPXH6101AC6U application, or MPXH6101AC6U equivalent, this page provides verified technical context, validated pin functions, confirmed operating characteristics, and real-world automotive and industrial use cases aligned with Freescale's MPXH6101A family specifications.
Technical Context
The MPXH6101AC6U integrates a piezoresistive silicon sensing element with on-chip bipolar signal conditioning, thin-film temperature compensation, and dual gain stages. Its transfer function VOUT = VS × (0.01059 × P − 0.10941) is calibrated across −40 °C to +125 °C, with offset stability of ±0.5% VFSS after 1000-hour stress testing.
It operates exclusively with dry air as pressure media and requires external decoupling (100 nF capacitor, 51 kΩ/47 pF RC filter) for A/D interfacing. The sealed vacuum reference enables true absolute pressure measurement, and fluorosilicone gel protects the die while transmitting pressure to the stainless steel-capped diaphragm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–102 kPa absolute - supports full MAP sensing for naturally aspirated and moderately boosted gasoline engines. |
| Supply Voltage | 4.75–5.25 Vdc - ratiometric operation ensures output scaling remains stable with supply variation. |
| Output Voltage | 0.168–4.933 Vdc - spans >4.7 V full-scale span, enabling 12-bit+ resolution without external amplification. |
| Accuracy | ±1.72% VFSS over 0–85 °C - includes linearity, TcOffset, TcSpan, hysteresis, and variation from nominal. |
| Response Time | 15 ms (10–90%) - sufficient for transient manifold pressure tracking in closed-loop fuel control. |
| Operating Temp | −40 to +125 °C - qualified for under-hood automotive environments with no derating required. |
| Sensitivity | 52.95 mV/kPa - linear coefficient directly usable in microcontroller pressure calculation firmware. |
Pinout & Package
MPXH6101AC6U uses the thermoplastic (PPS) Super Small Outline Package (SSOP), case 98ARH99066A - an 8-lead surface-mount package with stainless steel pressure cap on the P1 side and chamfered corner marking Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect - internal device connection; chamfered corner identifies this pin. |
| 2 | VS | Voltage supply input (4.75–5.25 Vdc); requires 100 nF decoupling capacitor to GND. |
| 3 | GND | Analog ground reference - must be connected to system AGND with low-impedance path. |
| 4 | VOUT | Analog output (0.168–4.933 Vdc); routed through 51 kΩ/47 pF RC filter before ADC input. |
| 5–8 | DNC | All unconnected - internal device connections; must remain floating, not tied to GND or any net. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over −40 °C to +125 °C - eliminates need for external calibration circuitry in ECU designs. |
| Fluorosilicone die protection | Enables reliable operation with dry air media while blocking contaminants from wire bonds and sensing element. |
| Ratiometric output | Output scales linearly with VS - allows shared 5 V rail with MCU, reducing BOM and improving noise rejection. |
| Sealed vacuum reference | Provides true absolute pressure measurement without external reference port or plumbing complexity. |
| SSOP surface-mount package | Case 98ARH99066A footprint supports automated assembly and meets under-hood thermal cycling requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6U | Wider 15–115 kPa range; same SSOP-8 package and pinout; ±2.0% VFSS accuracy over 0–85 °C. | Better suited for turbocharged engines or higher-altitude barometric sensing where extended upper range is required. | Select MPXH6115A6U only if system pressure exceeds 102 kPa; otherwise MPXH6101AC6U offers tighter accuracy within its range. |
| MPX5700AP | 70 kPa absolute range; SO-8 package; ±2.5% VFSS accuracy; requires external compensation for temperature. | Lower-cost option for non-automotive applications where 15–70 kPa coverage suffices and board space permits SO-8 footprint. | Choose MPX5700AP only when cost sensitivity outweighs accuracy and integration needs; MPXH6101AC6U provides superior on-chip compensation. |
Compared with MPXH6115A6U and MPX5700AP, the MPXH6101AC6U delivers the tightest accuracy (±1.72% VFSS) within its 15–102 kPa band and requires no external compensation components - making it optimal for cost-constrained, high-reliability automotive MAP systems.

FAQ
What is the pressure media compatibility of the MPXH6101AC6U?
The MPXH6101AC6U is qualified for use with dry air as the pressure media. Other media may adversely affect performance or long-term reliability due to chemical interaction with the fluorosilicone gel or stainless steel cap. Freescale explicitly states that media compatibility beyond dry air requires factory consultation - the MPXH6101AC6U is not rated for fuel, oil, or corrosive gases without validation.
Does the MPXH6101AC6U require external temperature compensation?
No, the MPXH6101AC6U includes fully integrated on-chip temperature compensation over −40 °C to +125 °C. Its block diagram confirms thin-film compensation circuitry and dual gain stages, and operating characteristics confirm ±1.72% VFSS error budget already includes TcOffset and TcSpan - no external thermistor or digital compensation is needed for specified accuracy.
What is the meaning of "DNC" pins on the MPXH6101AC6U pinout?
Pins 1 and 5–8 of the MPXH6101AC6U are marked DNC (Do Not Connect). Per Freescale's datasheet, these are internal device connections - not grounds, not shields, not test points. They must remain electrically floating and unconnected to any PCB net, including GND, to avoid disrupting internal biasing or causing measurement errors.
Can the MPXH6101AC6U operate from a 3.3 V supply?
No - the MPXH6101AC6U is specified only for 4.75–5.25 Vdc supply. Its transfer function, output voltage range (0.168–4.933 V), and internal biasing assume 5 V operation. At 3.3 V, output would fall below minimum specification, gain would deviate, and accuracy is not guaranteed; Freescale does not characterize or warrant operation outside the stated supply range.
Is the MPXH6101AC6U RoHS compliant and lead-free?
Yes - the MPXH6101AC6U is manufactured in accordance with RoHS Directive 2011/65/EU and uses lead-free terminations. Its package (case 98ARH99066A) and material declarations confirm compliance, and Freescale's revision history documents environmental qualification consistent with automotive-grade standards.
