Product details
Overview
MMA7660FCT from NXP Semiconductors (formerly Freescale) is a ±1.5 g, 3-axis capacitive MEMS accelerometer with I²C digital output, integrated low-pass filtering, 0g offset and gain compensation, and 6-bit resolution per axis. It delivers orientation detection, tap/shake gesture recognition, and auto-wake/sleep control for battery-constrained portable electronics.
For engineers reviewing the MMA7660FCT datasheet, MMA7660FCT pinout, MMA7660FCT application, or MMA7660FCT equivalent, this page provides verified technical context, real-world use cases, validated alternatives, and supply-ready procurement details - all grounded in the official Rev 8 (03/2012) Freescale datasheet and package documentation.
Technical Context
The MMA7660FCT integrates a polysilicon MEMS sensing element with an ASIC featuring switched-capacitor signal conditioning, finite-impulse-response (FIR) averaging over 32 samples per axis, and configurable I²C timing up to 400 kHz. Its internal 150 kHz oscillator drives sampling at user-selectable ODRs from 1 to 120 Hz.
It operates across three power states: Off Mode (0.4 µA), Standby Mode (≤10 µA), and Active Mode (47–294 µA depending on ODR), with autonomous transition between Auto-Wake (high-ODR) and Auto-Sleep (low-ODR) states triggered by motion events on any axis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Acceleration Range | ±1.5 g - Enables tilt detection and basic motion gestures without saturation in handheld device orientations. |
| Output Resolution | 6-bit digital (0–63 counts/axis) - Maps to ~21.33 counts/g; sufficient for orientation logic and low-complexity gesture classification. |
| Output Data Rate (ODR) | Configurable 1–120 Hz - Allows trade-off between motion responsiveness and power: 1 Hz for anti-theft sleep monitoring; 120 Hz for responsive tap detection. |
| Supply Current (Active) | 47 µA at 1 Hz, 294 µA at 120 Hz - Enables multi-day battery life in portable devices when paired with Auto-Sleep duty cycling. |
| Analog/Digital Voltage Ranges | AVDD: 2.4–3.6 V; DVDD: 1.71–3.6 V - Supports dual-rail operation with independent analog/digital supplies for noise isolation. |
| Interrupt Capabilities | INT pin supports 7 interrupt sources: GINT (data-ready), PLINT/FBINT (orientation), PDINT (tap), SHINTX/Y/Z (shake), ASINT (auto-sleep wake) - Enables event-driven firmware without polling. |
| Shock Survivability | 10,000 g - Ensures robustness against mechanical drop events during end-user handling. |
Pinout & Package
Package: 10-pin DFN (3 mm × 3 mm × 0.9 mm, Case 2002-03), bottom-exposed thermal pad, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 RESERVED | Analog ground reference | Must be connected to AVSS to maintain sensor bias stability and offset accuracy. |
| 2 N/C | No internal connection | Leave floating or tie to AVSS; no functional impact if unconnected. |
| 3 AVDD | Analog power supply | Primary power for MEMS transducer and analog front-end; requires local 0.1 µF decoupling to AVSS. |
| 4 AVSS | Analog ground | Reference return for AVDD and internal analog circuitry; must be low-impedance path to system ground. |
| 5 INT | Open-drain interrupt output | Asserts low on enabled events (e.g., tap, orientation change); requires external pull-up to DVDD. |
| 6 SCL | I²C clock input | Accepts standard-mode (100 kHz) or fast-mode (400 kHz) clock; 4.7 kΩ pull-up required. |
| 7 SDA | I²C data bidirectional | Open-drain interface; shares same 4.7 kΩ pull-up as SCL; supports multi-master arbitration. |
| 8 DVSS | Digital I/O ground | Return path for SCL, SDA, and INT; separate from AVSS to minimize digital noise coupling into analog domain. |
| 9 DVDD | Digital I/O power | Supplies logic levels for I²C interface and interrupt driver; requires local 0.1 µF decoupling to DVSS. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-Wake/Sleep with programmable thresholds | Reduces average current by switching between high-ODR (e.g., 32 Hz) on motion and low-ODR (e.g., 1 Hz) during idle - critical for always-on orientation sensing. |
| Tilt orientation detection (6-position) | Computes Left/Right/Up/Down/Back/Front states in real time using debounced X/Y/Z data; updates TILT register (0x03) only after stable consecutive readings per FILT[2:0]. |
| Tap detection with configurable threshold/duration | Uses PDET (0x09) and PD (0x0A) registers to detect transient acceleration exceeding 1.3 g for ≥10 ms - enables reliable single/double-tap UI without host CPU polling. |
| Shake detection per axis | Triggers SHINTX/Y/Z interrupts when |acceleration| > 1.3 g on respective axis - supports motion-initiated actions like screen rotation lock release. |
| On-chip FIR averaging (32-sample) | Reduces RMS noise to ±1 count (94% of samples) while preserving response time - eliminates need for external digital filtering in resource-limited microcontrollers. |
Applications
| Mobile Device Orientation | Gesture-Controlled UI |
|---|---|
|
Use Scenario: Smartphone or PMP automatically rotates display between portrait and landscape based on physical device tilt. IC Role / Device Role / Timing Role: MMA7660FCT continuously monitors static X/Y/Z gravity vectors and updates PoLa/BaFro bits in TILT register to determine orientation state. Use Value: Enables seamless UI adaptation without user intervention; leverages built-in debounce (FILT[2:0]) to prevent flicker during transitional angles. |
Use Scenario: User taps phone screen to mute audio or double-taps to launch camera app. IC Role / Device Role / Timing Role: MMA7660FCT detects transient acceleration peaks via PDINT interrupt and reports tap events directly to host MCU via I²C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis ±1.5 g I²C accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KXSC7-1051 (Kionix) | ±2 g range, 14-bit output, 1.71–3.6 V supply, 3.5 µA standby, 100 µA active @ 100 Hz | Higher resolution and wider range suit precision tilt; higher active current limits ultra-low-power use cases. | Select when higher dynamic range or finer orientation granularity is needed; verify I²C register map compatibility. |
| BMA220 (Bosch Sensortec) | ±2 g range, 10-bit output, 1.71–3.6 V supply, 4 µA standby, 140 µA active @ 100 Hz, built-in FIFO | Includes hardware FIFO and more advanced motion detection (no-shake/tap logic); larger footprint (2.0 × 2.0 mm). | Choose for systems requiring burst-mode data capture or enhanced gesture logic; note different pinout and interrupt behavior. |
Compared with KXSC7-1051 and BMA220, the MMA7660FCT offers the lowest active current at sub-10 Hz ODRs and simpler register-level configuration for basic orientation and tap - making it optimal for cost-sensitive, long-battery-life consumer devices where 6-bit resolution suffices.

FAQ
What is the operating temperature range for the MMA7660FCT?
The MMA7660FCT is rated for continuous operation from –40°C to +85°C. This range is validated per Freescale's Rev 8 datasheet and supports deployment in consumer electronics exposed to ambient environmental extremes, including automotive-adjacent portable devices and outdoor handheld equipment. The MMA7660FCT maintains specified offset drift (±1.5 mg/°C max) and sensitivity variation (±0.01%/°C) across this full range.
Does the MMA7660FCT support self-test functionality?
No, the MMA7660FCT does not include an electrostatic self-test feature. As explicitly stated in the Rev 8 datasheet (page 11), "MMA7660FC does not include an accelerometer self test function." Verification of functionality must be performed through external mechanical stimulus or by entering Test Mode (disabling MEMS measurement and writing synthetic 6-bit values to XOUT/YOUT/ZOUT registers) to validate interrupt and register behavior.
How is the MMA7660FCT's interrupt pin (INT) configured electrically?
The MMA7660FCT's INT pin is an open-drain output requiring an external pull-up resistor to DVDD. Per the datasheet (Table 1, Figure 2), it sinks current when asserted low for any enabled interrupt source (e.g., GINT, PDINT, SHINTX). The recommended pull-up is 4.7 kΩ, and the pin can drive ≥6 mA. This configuration allows wired-OR connection of multiple interrupt sources on a shared MCU interrupt line.
Can the MMA7660FCT operate with different analog and digital supply voltages?
Yes, the MMA7660FCT supports independent analog (AVDD: 2.4–3.6 V) and digital (DVDD: 1.71–3.6 V) supplies. This dual-rail architecture isolates noise-sensitive analog sensing circuitry from digital switching noise. The datasheet specifies that AVDD and DVDD may differ (e.g., AVDD = 2.8 V, DVDD = 1.8 V), enabling optimized power domain partitioning in mixed-voltage systems.
What is the maximum I²C clock frequency supported by the MMA7660FCT?
The MMA7660FCT supports Fast Mode I²C up to 400 kHz, as confirmed in Table 4 (I²C Interface Speed) and Section 22 (Serial Interface). This allows efficient register access and data reads without bottlenecking host MCU throughput. Timing compliance is guaranteed across the full operating voltage and temperature range, with defined setup/hold times documented in Appendix D.
