Product details
Overview
MMA6263Q from Freescale Semiconductor is a ±1.5g dual-axis capacitive micromachined accelerometer with integrated signal conditioning, 900 Hz bandwidth, 2.2 mA supply current, and ratiometric linear output voltage for X/Y axes - used in real-time motion sensing and impact detection systems requiring fast response and low-noise analog interface.
For engineers reviewing the MMA6263Q datasheet, MMA6263Q pinout, MMA6263Q application, or MMA6263Q equivalent, this page delivers verified technical context, QFN-16 package mapping, self-test functionality details, noise performance (2.5 mVRMS, 0.1 Hz–1 kHz), and direct alternatives for tilt, vibration, and freefall monitoring designs.
Technical Context
The MMA6263Q implements a surface-micromachined polysilicon g-cell with back-to-back capacitive sensing, paired with a switched-capacitor ASIC that performs gain, filtering, temperature compensation, and EEPROM-trimmed calibration. Its 900 Hz –3 dB bandwidth is factory-set without external components.
Signal path includes dedicated X/Y integrators, low-pass filtering, and ratiometric output scaling - where VOUT = VDD/2 ± (S × acceleration), enabling direct ADC interfacing without supply-voltage error correction. Self-test applies electrostatic force via ST pin to verify mechanical and electrical integrity in-system.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acceleration Range | ±1.5 g full-scale - defines measurable dynamic range for tilt, shock, and motion events without saturation. |
| Bandwidth (–3 dB) | 900 Hz - supports high-speed motion capture including impact transients and rapid orientation changes. |
| Supply Current | 2.2 mA typical - enables battery-powered operation with predictable power budget in portable devices. |
| Output Noise (RMS) | 2.5 mVRMS (0.1 Hz–1 kHz) - sets minimum detectable acceleration resolution (~3.1 mg/√Hz PSD). |
| Sensitivity | 800 mV/g typical - yields ~1.2 V full-scale swing (±1.5 g) at 3.3 V supply, compatible with 12-bit ADCs. |
| Power-Up Response | 0.7 ms - ensures rapid system readiness after wake-up, critical for event-triggered data logging. |
| Self-Test Output | VST = 0.9 × VDD - provides deterministic voltage shift for functional verification without mechanical stimulus. |
Pinout & Package
Package: 16-lead QFN (Case 1477-02), 6 mm × 6 mm × 1.98 mm, exposed thermal flag (ground-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XOUT (Pin 15) | Analog output, X-axis acceleration | Ratiometric voltage centered at VDD/2; ±1.5 g yields ±1.2 V swing at 3.3 V supply. |
| YOUT (Pin 14) | Analog output, Y-axis acceleration | Independent ratiometric output identical in scale and offset to XOUT for orthogonal sensing. |
| ST (Pin 12) | Digital input, self-test enable | Logic-high (≥0.7×VDD) initiates calibrated electrostatic deflection; response time ≤2.0 ms. |
| VDD (Pin 3) | Power supply input | 2.7–3.6 V operation; internal regulation not required; 0.1 µF decoupling mandatory per layout guidelines. |
| VSS (Pin 4) | Ground reference | Must connect to low-impedance system ground; exposed flag underneath package is tied to VSS. |
| N/C (Pins 1,2,5–7,8–11,13,16) | No internal connection | Unbonded or factory-trim pads; must remain unconnected to avoid parasitic coupling or latch-up. |
Key Features
| Feature | Design Value |
|---|---|
| Onboard 1-pole switched-capacitor filter | Eliminates need for external RC components while maintaining precise 900 Hz cutoff and phase stability. |
| Factory-calibrated zero-g offset & sensitivity | Removes requirement for system-level trimming; offset drift <2.0 mg/°C ensures stable baseline over temperature. |
| Ratiometric output architecture | Compensates for VDD variation in ADC reference path - eliminates separate voltage reference IC in microcontroller interfaces. |
| Integrated self-test with fault latch | Verifies g-cell movement and signal chain integrity; EEPROM parity check disables ST if calibration data corruption detected. |
| Robust mechanical design | Survives ±2000 g shocks and 1.2 m drop tests - suitable for handheld, industrial, and appliance environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-axis analog accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMA6262Q | 150 Hz bandwidth, 2.2 mA IDD, 1.3 mVRMS noise (0.1 Hz–1 kHz) | Better low-frequency SNR but insufficient for impact transients above 200 Hz | Select when prioritizing ultra-low noise over high-speed event capture |
| MMA6261Q | 300 Hz bandwidth, 1.2 mA IDD, 3.5 mVRMS noise (0.1 Hz–1 kHz) | Lower power and wider bandwidth than MMA6260Q but lower than MMA6263Q | Select when balancing power, noise, and mid-bandwidth requirements for portable tilt sensing |
Compared with MMA6262Q and MMA6261Q, the MMA6263Q delivers the highest usable bandwidth (900 Hz) in the series while maintaining identical QFN-16 packaging and pinout - making it the only choice for applications demanding both fast transient response and analog output compatibility with legacy MMA62xx layouts.

FAQ
What is the operating voltage range for the MMA6263Q?
The MMA6263Q operates from 2.7 V to 3.6 V DC. Within this range, it functions as a fully calibrated linear accelerometer with ratiometric output scaling. Operation outside this window may yield linear output but without guaranteed calibration accuracy. The device draws 2.2 mA typical at 3.3 V, and its internal circuitry requires a 0.1 µF ceramic capacitor directly at the VDD pin for stable operation.
How does the self-test function work on the MMA6263Q?
The MMA6263Q self-test applies an electrostatic force to the movable g-cell plate via the ST pin. When driven high (≥0.7×VDD), it generates a known deflection producing a predictable output shift - typically 0.9×VDD at the affected axis output. This verifies both mechanical integrity of the sensor element and functionality of the analog signal chain. Response settles within 2.0 ms, and the feature is disabled if EEPROM parity errors are detected.
Is the MMA6263Q pin-compatible with other devices in the MMA6200 series?
Yes, the MMA6263Q shares identical QFN-16 packaging (Case 1477-02), pin count, pin locations, and pin functions with all members of the MMA6200 series, including MMA6260Q, MMA6261Q, and MMA6262Q. This allows direct substitution on existing PCBs without layout modification - though bandwidth, noise, and current draw differ between variants.
What is the significance of ratiometric output in the MMA6263Q?
Ratiometric output means both zero-g offset and sensitivity scale linearly with VDD. For example, at 3.3 V supply, zero-g is 1.65 V and sensitivity is 800 mV/g; at 3.0 V, those values scale to 1.5 V and ~727 mV/g. This enables direct connection to an MCU's ADC using the same VDD as reference, eliminating supply-induced conversion errors - a key advantage in cost-sensitive embedded systems.
Can the MMA6263Q be used in high-shock environments such as power tools or industrial equipment?
Yes, the MMA6263Q is rated for ±2000 g mechanical shock and survives 1.2 m drops onto concrete - validated per Freescale's mechanical test specifications. Its robust polysilicon g-cell and hermetic wafer-level packaging make it suitable for high-vibration applications like power tool activity detection, motor imbalance monitoring, and condition-based maintenance systems where reliability under stress is essential.
