Product details
Overview
MPXH6101AC6T1 from Freescale 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 - designed for manifold absolute pressure (MAP) sensing in engine control systems to compute cylinder fuel delivery.
For engineers reviewing the MPXH6101AC6T1 datasheet, MPXH6101AC6T1 pinout, MPXH6101AC6T1 application, or MPXH6101AC6T1 equivalent, this page delivers verified technical context, validated pin functions, real-world automotive and embedded use cases, and confirmed alternative options aligned with Freescale's documented specifications and package constraints.
Technical Context
The MPXH6101AC6T1 integrates a piezoresistive silicon sensing element with on-chip bipolar signal conditioning, thin-film temperature compensation, and dual-stage gain amplification - delivering a stable analog voltage output proportional to absolute pressure across its 15–102 kPa range. It operates ratiometrically with 4.75–5.25 V supply and exhibits 15 ms response time.
Its internal architecture includes a sealed vacuum reference cavity, fluorosilicone gel die protection, and stainless steel cap for P1-side media exposure. The device is calibrated and compensated over –40 °C to +125 °C operating temperature, with offset stability of ±0.5% VFSS after 1000-hour stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–102 kPa absolute - covers typical automotive intake manifold pressures at sea level to high-altitude operation. |
| Supply Voltage | 4.75–5.25 Vdc - ratiometric operation ensures output scaling remains consistent with ADC reference voltage. |
| Full-Scale Output | 4.775–4.933 Vdc at 102 kPa - enables direct interface with 5 V microcontroller ADCs without level-shifting. |
| Accuracy | ±1.72% VFSS over 0–85 °C - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 15 ms (10%–90%) - supports real-time closed-loop fuel injection timing in gasoline and flex-fuel engines. |
| Sensitivity | 52.95 mV/kPa - provides high-resolution pressure differentiation within narrow engine load bands. |
| Operating Temp | –40 °C to +125 °C - meets under-hood automotive ambient requirements with full functionality. |
Pinout & Package
MPXH6101AC6T1 uses the 8-lead Super Small Outline Package (SSOP), case 98ARH99066A, with thermoplastic (PPS) body and stainless steel pressure port cap. Pin 1 is identified by chamfered corner; pins 1, 5–8 are internal DNC connections and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Internal connection - no external circuitry or grounding permitted; chamfered corner identifies this pin. |
| 2 | VS | Voltage supply input - accepts 4.75–5.25 Vdc; requires 100 nF decoupling capacitor per recommended layout. |
| 3 | GND | Analog ground reference - must be connected to system ground plane with low-impedance path. |
| 4 | VOUT | Analog output voltage - ratiometric, 0.168–4.933 Vdc range; interfaces directly to 10- or 12-bit ADC inputs. |
| 5–8 | DNC | Do not connect - internal device connections only; floating or grounded traces cause calibration drift or damage. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Compensated over –40 °C to +125 °C - eliminates need for external thermal correction in engine bay environments. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture, oil vapor, and combustion byproducts while transmitting pressure accurately. |
| Sealed vacuum reference | Enables true absolute pressure measurement - critical for barometric correction and altitude-compensated fuel mapping. |
| Ratiometric output | Output scales linearly with supply voltage - maintains accuracy even with ±2.5% VS variation common in vehicle electrical systems. |
| SSOP surface-mount package | Case 98ARH99066A footprint - compatible with standard reflow processes and automated assembly for high-volume automotive production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6T1 | Wider 15–115 kPa range; same SSOP-8 package and pinout; ±2.0% VFSS accuracy over 0–85 °C. | Supports higher boost pressures in turbocharged engines; slightly reduced accuracy tolerance. | Select when extended upper-range coverage is required and ±0.28% additional error budget is acceptable. |
| MPX5700AP | 700 kPa range; SO-8 package; different pinout (VS/VOUT/GND on pins 1/2/3); ±2.5% VFSS accuracy. | Designed for high-pressure hydraulic or industrial pneumatic systems - not drop-in for MAP applications. | Use only in non-automotive contexts requiring >102 kPa capability; requires PCB redesign and firmware scaling updates. |
Compared with MPXH6101AC6T1, MPXH6115A6T1 offers broader pressure coverage with identical mounting and interface, while MPX5700AP serves entirely different pressure domains and demands mechanical and electrical redesign - neither is pin-compatible, but both address adjacent sensing needs in Freescale's portfolio.

FAQ
What is the pressure range and accuracy specification of the MPXH6101AC6T1?
The MPXH6101AC6T1 has a specified absolute pressure range of 15–102 kPa and an accuracy of ±1.72% full-scale span (VFSS) over 0 °C to 85 °C. This includes contributions from linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset. The device is calibrated and tested per Freescale Document Number MPXH6101A Rev. 7.1, with all values traceable to the published datasheet operating characteristics table.
Is the MPXH6101AC6T1 pin-compatible with other Freescale MAP sensors like MPXH6115A6T1?
Yes, the MPXH6101AC6T1 shares identical pinout, package (case 98ARH99066A), and terminal assignments with MPXH6115A6T1 - both use VS/VOUT/GND on pins 2/4/3 respectively and DNC on pins 1 and 5–8. However, their transfer functions differ due to distinct pressure ranges, so firmware scaling must be updated when substituting MPXH6115A6T1 for MPXH6101AC6T1.
What is the recommended decoupling circuit for MPXH6101AC6T1 power supply?
Freescale specifies a 100 nF ceramic capacitor between VS and GND, placed as close as possible to pins 2 and 3. For output filtering, a 51 kΩ resistor and 47 pF capacitor form an RC low-pass network between VOUT and the ADC input, as shown in Figure 4 of the MPXH6101A datasheet. This configuration suppresses high-frequency noise while preserving 15 ms step response integrity.
Can the MPXH6101AC6T1 be used with media other than dry air?
No - Freescale explicitly states that MPXH6101AC6T1 operating characteristics and long-term reliability are validated only with dry air as the pressure medium. Exposure to oil, fuel vapor, coolant, or corrosive gases may degrade fluorosilicone gel performance or cause irreversible sensor drift. Media compatibility testing must be conducted separately with Freescale/NXP engineering support before deployment.
Does the MPXH6101AC6T1 require external temperature compensation?
No - the MPXH6101AC6T1 features fully integrated on-chip temperature compensation over –40 °C to +125 °C, implemented via thin-film resistors and bipolar gain stages. No external thermistor, lookup table, or digital compensation algorithm is needed for operation within its rated temperature range, simplifying ECU firmware and hardware design.
