Product details
Overview
MMA2206KEGR2 from NXP Semiconductors (formerly Freescale) is a surface-mount, silicon capacitive, micromachined X-axis accelerometer with ±80g full-scale range, ratiometric linear output, and integrated 4th-order Bessel low-pass filter (360–440 Hz). It features factory-calibrated zero-g offset, self-test capability, and AEC-Q100 Grade 2 qualification (−40°C to +125°C), used in automotive crash sensing and industrial vibration monitoring.
For engineers reviewing the MMA2206KEGR2 datasheet, MMA2206KEGR2 pinout, MMA2206KEGR2 application, or MMA2206KEGR2 equivalent, key selection criteria include its SOIC-16 package, 3.0–6.0 mA supply current, 110 mVRMS noise (10 Hz–1 kHz), status-fault latching behavior, and self-test output response of 8.4–15.6 g.
Technical Context
The MMA2206KEGR2 integrates a polysilicon MEMS g-cell with a CMOS ASIC containing switched-capacitor signal conditioning, temperature compensation, and a fully integrated 4-pole Bessel filter-no external components required. Its ratiometric output scales with VDD (4.75–5.25 V), and zero-g offset is trimmed via EPROM.
Self-test applies electrostatic force to deflect the movable plate, producing a calibrated output shift; fault detection monitors low-voltage (2.7–4.0 V trip), clock frequency (50–260 kHz), and EPROM parity, latching STATUS high until reset by ST pulse ≥100 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Range | ±80 g - defines maximum measurable acceleration before saturation; supports high-shock impact detection. |
| Supply Voltage | 4.75–5.25 V - operation within this range guarantees full calibration; outside range yields linear but uncalibrated output. |
| Bandwidth (−3 dB) | 360–440 Hz - preserves pulse shape integrity for transient vibration analysis without phase distortion. |
| Output Noise (RMS) | 110 mVRMS (10 Hz–1 kHz) - sets minimum detectable acceleration resolution in low-frequency monitoring. |
| Self-Test Output Shift | 8.4–15.6 g - provides deterministic mechanical-electrical verification prior to deployment or during runtime. |
| Status Fault Latch | Latches high on LVD, clock failure, or EPROM parity error - enables persistent fault indication without continuous polling. |
| Operating Temp Range | −40°C to +125°C - qualified per AEC-Q100 Rev. F Grade 2 for under-hood automotive use. |
Pinout & Package
Package: 16-lead SOIC (Case 475-01), Pb-free, tape-and-reel packaging (R2 suffix). Hermetically sealed at wafer level for reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 9–13, 14–16 | No Connect (N/C) | Internally unconnected; must be left floating per layout guidelines to avoid coupling noise or parasitic paths. |
| 4 (ST) | Self-Test Input | Active-high logic input; initiates electrostatic self-test; internal pull-down prevents false triggering. |
| 5 (VOUT) | Analog Output | Ratiometric voltage output (0.45–0.55 × VDD at zero-g); requires RC filter (1 kΩ + 0.01 µF) to suppress clock noise. |
| 6 (STATUS) | Fault Status Output | Open-drain logic output; latches high on fault; reset by ≥100 µs ST pulse unless fault persists. |
| 7 (VSS) | Ground Reference | Primary power return; must connect to clean analog ground plane beneath device per PCB layout guidance. |
| 8 (VDD) | Power Supply | 4.75–5.25 V supply; requires 0.1 µF decoupling capacitor placed adjacent to pin per layout rules. |
Key Features
| Feature | Design Value |
|---|---|
| 4th-order Bessel filter | Preserves time-domain pulse fidelity for impact waveform capture without overshoot or ringing. |
| Factory-trimmed zero-g offset | Eliminates need for external calibration circuitry or software compensation in production systems. |
| Hermetic wafer-level seal | Prevents moisture/contaminant ingress, enabling long-term stability in automotive and industrial enclosures. |
| Integrated fault detection | Monitors supply, clock, and memory integrity autonomously-reducing host MCU diagnostic overhead. |
| Ratiometric output scaling | Output tracks VDD variations, simplifying interface to ADCs sharing same reference voltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL326BCPZ-RL7 | Wider ±16 g range, higher 5.5 kHz bandwidth, no integrated self-test or STATUS latch. | Better suited for high-frequency vibration analysis; lacks built-in fault diagnostics for safety-critical systems. | Select when bandwidth >1 kHz is required and system-level fault monitoring is handled externally. |
| MMA8452Q | I²C digital output, 12-bit resolution, embedded motion detection, lower power (150 µA in standby). | Designed for battery-powered IoT nodes; requires host MCU for configuration and data parsing. | Select for smart sensor nodes needing programmability and ultra-low power, not analog simplicity or self-contained diagnostics. |
Compared with ADXL326BCPZ-RL7 and MMA8452Q, the MMA2206KEGR2 uniquely combines analog ratiometric output, integrated Bessel filtering, self-test, and fault-latched STATUS in a single SOIC-16 package-making it optimal for deterministic, safety-aware analog-sensor applications where minimal host intervention is required.

FAQ
What is the operating supply voltage range for the MMA2206KEGR2?
The MMA2206KEGR2 operates within a supply voltage range of 4.75 V to 5.25 V. Within this window, the device delivers fully calibrated, ratiometric output. Operation outside this range may yield linear but uncalibrated performance, and the low-voltage detect circuit triggers between 2.7 V and 4.0 V, asserting the STATUS pin if VDD falls below the trip threshold.
How does the self-test function work on the MMA2206KEGR2?
The MMA2206KEGR2 self-test applies an electrostatic force to the MEMS g-cell's movable plate via the ST pin, causing a calibrated deflection equivalent to 8.4–15.6 g. This produces a corresponding shift in VOUT, verifying both mechanical integrity and signal chain functionality. The STATUS pin reflects test initiation and latches faults independently.
What is the purpose of the STATUS pin on the MMA2206KEGR2?
The STATUS pin on the MMA2206KEGR2 is an open-drain output that latches high upon occurrence of any fault condition-including low-voltage detection, clock monitor failure (50–260 kHz violation), or EPROM parity error. It remains asserted until reset by a ≥100 µs high pulse on ST, unless the underlying fault persists.
Does the MMA2206KEGR2 require external filtering components?
Yes-the MMA2206KEGR2's VOUT requires an external RC filter (1 kΩ series resistor + 0.01 µF to ground) to suppress clock noise from its internal switched-capacitor filter. Additionally, a 0.1 µF decoupling capacitor is mandatory on VDD, and PCB layout must include a solid ground plane beneath the device to minimize noise coupling.
Is the MMA2206KEGR2 pin-compatible with other devices in the MMA2206 family?
Yes-the MMA2206KEGR2 shares identical pinout, package (SOIC-16, Case 475-01), and electrical interface with MMA2206EG, MMA2206EGR2, and MMA2206KEG. Differences are limited to Pb-free compliance (KEG suffix) and tape-and-reel packaging (R2 suffix); all variants use the same functional block diagram and timing behavior.
