Product details
Overview
MMA6263QR2 from Freescale Semiconductor is a ±1.5g dual-axis capacitive micromachined accelerometer with integrated signal conditioning, ratiometric analog outputs (XOUT/YOUT), and factory-trimmed 900 Hz bandwidth. It operates from 2.7 V to 3.6 V, draws 2.2 mA, and delivers 800 mV/g sensitivity with ±1.0% FSO nonlinearity-designed for high-dynamic-range motion sensing in portable industrial devices.
For engineers reviewing the MMA6263QR2 datasheet, MMA6263QR2 pinout, MMA6263QR2 application, or MMA6263QR2 equivalent, key selection criteria include its 900 Hz bandwidth, self-test capability via ST pin, QFN-16 package with exposed thermal flag, and ratiometric output behavior critical for ADC interfacing in battery-powered systems.
Technical Context
The MMA6263QR2 implements a surface-micromachined polysilicon g-cell with back-to-back capacitive sensing elements, paired with a switched-capacitor ASIC that performs on-chip signal conditioning, temperature compensation, and single-pole low-pass filtering. Its 900 Hz bandwidth is set entirely by internal clocking-no external components required.
Self-test is activated by applying logic-high to the ST pin, generating electrostatic deflection of the movable plate; output response is 0.9×VDD, verified within 2.0 ms. The device maintains ratiometric performance: zero-g offset (1.65 V at VDD = 3.3 V) and sensitivity scale linearly with supply voltage, enabling supply-noise rejection in microcontroller ADC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acceleration Range | ±1.5 g full-scale range-supports tilt, impact, and vibration detection without saturation in handheld and appliance applications. |
| Bandwidth | 900 Hz −3 dB point-enables accurate capture of rapid motion transients such as drop events or motor startup vibrations. |
| Sensitivity | 800 mV/g typical-provides 1.2 V differential output swing across full scale (±1.5 g), simplifying analog front-end gain staging. |
| Supply Current | 2.2 mA typical at 3.3 V-optimized for always-on motion monitoring in power-constrained portable electronics. |
| Output Type | Ratiometric analog voltage (XOUT/YOUT)-offset and gain track VDD, eliminating need for separate voltage reference in MCU ADC designs. |
| Nonlinearity | ±1.0 %FSO-ensures sub-degree tilt accuracy and reliable freefall threshold detection without software calibration. |
| Self-Test Response | 0.9 × VDD output shift-verifies mechanical integrity and signal chain functionality in-system prior to deployment. |
Pinout & Package
Package: 16-lead QFN (Case 1477-02), 6 mm × 6 mm × 1.98 mm, exposed thermal flag (connected to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5–7, 13, 16 | N/C | No internal connection-must remain unconnected; not for factory trim (pins 2, 8–11 are trim-only and also N/C). |
| 2, 8–11 | N/C (Factory Trim) | Reserved for internal EEPROM trimming-electrically isolated from user circuitry; leave unconnected. |
| 3 | VDD | Positive supply input (2.7–3.6 V); requires local 0.1 µF decoupling capacitor to ground. |
| 4 | VSS | Power ground; connected internally to exposed thermal flag-must be soldered to PCB ground plane. |
| 12 | ST | Active-high self-test enable input; internal 57 kΩ pull-down ensures safe default state-no external resistor needed. |
| 14 | YOUT | Analog output for Y-axis acceleration; ratiometric voltage (VSS + 0.25 V to VDD – 0.25 V), 50 Ω output impedance. |
| 15 | XOUT | Analog output for X-axis acceleration; identical electrical characteristics to YOUT-dual independent channels. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Signal Conditioning | On-chip ASIC provides amplification, filtering, and temperature compensation-eliminates external op-amps and passive RC networks. |
| Self-Test Functionality | Electrostatic actuation via ST pin verifies both mechanical g-cell and analog signal path integrity in <2 ms-critical for safety-critical deployments. |
| Ratiometric Output Behavior | Zero-g offset and sensitivity scale linearly with VDD-enables direct connection to MCU ADC without external voltage reference or supply-error correction. |
| Robust Mechanical Design | Withstands ±2000 g shock and survives 1.2 m concrete drop tests-suitable for ruggedized consumer and industrial equipment. |
| Low-Power Operation | 2.2 mA supply current at 3.3 V with 900 Hz bandwidth-balances responsiveness and battery life in always-on motion monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-axis analog-output accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMA6262QR2 | 150 Hz bandwidth, 2.2 mA supply current, 1.3 mVrms noise | Better low-frequency stability and lower noise for slow-motion tilt or static position sensing | Select MMA6262QR2 when bandwidth >300 Hz is unnecessary and ultra-low noise is prioritized over transient response. |
| ADXL202E | 500 Hz bandwidth, digital PWM output, 0.5 mA supply current, ±2 g range | Requires external RC filter for analog conversion; lacks ratiometric voltage output | Choose ADXL202E only if system already uses PWM-input peripherals and ultra-low power (<1 mA) dominates over analog interface simplicity. |

FAQ
What is the operating voltage range for the MMA6263QR2?
The MMA6263QR2 operates from 2.7 V to 3.6 V. Within this range, it functions as a fully calibrated linear accelerometer; operation outside these limits may yield linear output but without guaranteed calibration accuracy. The device draws 2.2 mA typical at 3.3 V, making it suitable for 3.3 V rail systems with moderate power budgets. Voltage tolerance is specified to −0.3 V to +3.6 V absolute maximum.
Does the MMA6263QR2 require external components for basic operation?
No, the MMA6263QR2 requires only a 0.1 µF ceramic capacitor between VDD and VSS for power supply decoupling. Its onboard switched-capacitor filter sets the 900 Hz bandwidth without external resistors or capacitors. Ratiometric outputs eliminate the need for a separate voltage reference, and the internal 57 kΩ pull-down on the ST pin removes requirement for external biasing.
How does the self-test function work on the MMA6263QR2?
The MMA6263QR2 self-test is initiated by driving the ST pin high, which applies a calibrated electrostatic force to the movable g-cell plate. This causes measurable deflection, resulting in a known output shift of 0.9 × VDD on both XOUT and YOUT. Response occurs within 2.0 ms, verifying mechanical integrity and full analog signal chain functionality-including ASIC, filters, and output drivers-without external test equipment.
What is the significance of ratiometric output in the MMA6263QR2?
Ratiometric output means both zero-g offset (1.65 V at 3.3 V) and sensitivity (800 mV/g) scale linearly with VDD. When interfaced with an MCU's internal ADC using the same VDD as reference, supply voltage variations cancel out-eliminating measurement error from battery droop or regulator ripple. This behavior is intrinsic to the MMA6263QR2's architecture and requires no additional circuitry.
Is the MMA6263QR2 pin-compatible with other devices in the MMA6260Q series?
Yes, all devices in the MMA6260Q series-including MMA6260Q, MMA6261Q, MMA6262Q, and MMA6263Q-share identical QFN-16 (Case 1477-02) pinout and footprint. Bandwidth, supply current, and noise performance differ by variant, but PCB layout, decoupling, and interface circuitry remain interchangeable across the family for design flexibility and BOM consolidation.
