Product details
Overview
FXLN8362QR1 from NXP Semiconductors (formerly Freescale) is a 3-axis analog-output accelerometer with ±4 g / ±16 g full-scale range selection, low-power operation (180 µA typical active current), fixed 0.75 V zero-g output offset, and low-bandwidth configuration (1.1 kHz XY / 600 Hz Z). It serves as a motion-sensing front-end in tilt, vibration, and activity monitoring systems operating from –40 °C to +105 °C.
For engineers reviewing the FXLN8362QR1 datasheet, FXLN8362QR1 pinout, FXLN8362QR1 application, or FXLN8362QR1 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for industrial motion sensing designs requiring stable analog acceleration outputs and configurable g-range.
Technical Context
The FXLN8362QR1 integrates a MEMS acceleration sensor with a CMOS ASIC that provides internally compensated analog outputs for X, Y, and Z axes - each buffered and referenced to a supply-independent 0.75 V zero-g level. Its g-range is selected dynamically via the g-Select pin: logic high enables ±4 g mode (114.5 mV/g sensitivity), logic low enables ±16 g mode (28.62 mV/g).
Bandwidth is factory-configured to low mode (1.1 kHz on X/Y, 600 Hz on Z) and adjusted externally using 9.1 nF capacitors on all three output pins. The device supports self-test activation via ST pin and power management via EN pin, entering <30 nA shutdown current when EN is low.

Pinout & Package
FXLN8362QR1 uses a 3 mm × 3 mm × 1 mm, 12-pin QFN package (Case 2300-01, 0.65 mm pitch) with exposed pad (EP) not to be soldered. Pin 1 is marked by top-side dot; pin numbering follows standard counter-clockwise layout from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BYP | Internal regulator output capacitor node | Stabilizes internal 1.5 V regulator; requires 100 nF ceramic capacitor to GND for noise immunity |
| VDD | Main supply input | Accepts 1.71–3.6 V; must ramp before enabling EN to avoid startup failure |
| ST | Self-test control input | Logic high applies electrostatic actuation force - verifies sensor and signal path integrity without mechanical stimulus |
| EN | Power enable input | Logic low disables internal circuitry, reducing current to 30 nA; logic high enables full operation |
| g-Select | Full-scale range selector | High = ±4 g (114.5 mV/g); low = ±16 g (28.62 mV/g); transition delay ≤340 µs |
| GND (Pins 6 & 7) | Dual ground connections | Provides low-impedance return path for analog and digital sections; improves PSRR and noise rejection |
| ZOUT | Z-axis analog output | Buffered voltage output with 0.75 V zero-g offset; bandwidth set by external capacitor (9.1 nF) |
| YOUT | Y-axis analog output | Same zero-g offset and bandwidth configuration as ZOUT; independent of X/Y orientation |
| XOUT | X-axis analog output | Matches YOUT electrical behavior; all three outputs share identical DC offset and AC response tuning |
| NC (Pins 11 & 12) | No-connect terminals | May be left floating or tied to GND; no internal connection - no impact on performance or reliability |
Key Features
| Feature | Design Value |
|---|---|
| Supply-Independent Zero-G Offset | 0.75 V ±45 mV across 1.71–3.6 V VDD - eliminates need for ratiometric ADC or supply monitoring in low-cost systems |
| Dynamically Configurable Full-Scale Range | ±4 g / ±16 g selection via single logic-level g-Select pin - enables one BOM to serve multiple mechanical shock/vibration profiles |
| Low-Power Analog Interface | 180 µA active current with buffered 10 kΩ outputs - directly drives RC filters or 12-bit SAR ADCs without op-amp buffering |
| Integrated Self-Test | Electrostatic actuation on ST pin validates sensor integrity and analog chain - replaces manual calibration checks in production test |
| Robust Mechanical Rating | 10,000 g shock survivability - withstands board-level reflow, drop testing, and harsh industrial handling without parameter shift |
Applications
| Tamper Detection System | White Goods Tilt/Vibration Monitor |
|---|---|
Use Scenario: Detect unauthorized physical movement or enclosure opening in utility meters or secure enclosures. IC Role / Device Role / Timing Role: Analog acceleration front-end capturing low-frequency displacement events with ±16 g range for impact detection. Use Value: Enables reliable tamper flag generation using only the FXLN8362QR1's self-test and g-Select pin - no external comparator or microcontroller required for basic alerting. |
Use Scenario: Monitor drum imbalance, door closure angle, or transport-induced vibration in washing machines and dryers. IC Role / Device Role / Timing Role: Low-bandwidth (1.1 kHz XY / 600 Hz Z) analog sensor feeding MCU ADC for real-time tilt and shake classification. Use Value: Fixed 0.75 V zero-g offset ensures consistent baseline across temperature and supply variation - critical for repeatable threshold-based diagnostics. |
| Industrial Robotics Inclinometer | Sports Activity Tracker |
Use Scenario: Measure joint angle or platform inclination in collaborative robot end-effectors or mobile base leveling systems. IC Role / Device Role / Timing Role: High-accuracy ±4 g analog output source with <±2 mg/°C zero-g drift - used for static tilt calculation via arctangent of X/Z or Y/Z ratios. Use Value: 114.5 mV/g sensitivity at ±4 g provides >10-bit effective resolution with 12-bit ADC - sufficient for <0.1° tilt resolution over ±30° range. |
Use Scenario: Capture repetitive motion patterns (walking, running, cycling) in wearable fitness bands or medical rehab devices. IC Role / Device Role / Timing Role: Low-current (180 µA) analog motion sensor operating from coin cell, with ±16 g range for impact event capture during falls or jumps. Use Value: Dual g-range capability allows same firmware to interpret both subtle gait dynamics (±4 g) and high-impact events (±16 g) - reducing sensor count per device. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog-output accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FXLN8372QR1 | Same package and pinout; high-bandwidth mode (2.7 kHz XY / 600 Hz Z) factory-configured; otherwise identical electrical interface and g-range options | Required for higher-frequency vibration analysis (e.g., motor bearing fault detection) where 1.1 kHz limit of FXLN8362QR1 is insufficient | Select FXLN8372QR1 only if system demands >1.1 kHz XY bandwidth; no PCB change needed but external capacitor values differ (8.2 nF on Z, 3.3 nF on X/Y) |
| MMA8452QT | Digital I²C output; 12-bit resolution; ±2/±4/±8 g ranges; 200 µA active current; lacks analog outputs and fixed zero-g offset | Suitable for microcontroller-based systems with I²C interface and onboard digital filtering; not drop-in for analog-signal-chain designs | Choose MMA8452QT when digital integration, embedded FIFO, or motion detection interrupts are required - not for direct replacement of FXLN8362QR1's analog interface |
Compared with FXLN8362QR1, FXLN8372QR1 offers higher XY bandwidth with identical pinout and analog interface, while MMA8452QT shifts to digital I²C output and removes the supply-independent 0.75 V reference - making it incompatible for analog-signal-path continuity but advantageous for firmware-controlled motion processing.

FAQ
What is the full-scale range configuration method for FXLN8362QR1?
The FXLN8362QR1 supports ±4 g and ±16 g full-scale ranges selected dynamically via its g-Select pin: logic high configures ±4 g (114.5 mV/g sensitivity), logic low configures ±16 g (28.62 mV/g). This selection is active immediately after g-Select transition, with ≤340 µs settling time. No register writes or external programming are required - the function is purely hardware-controlled and fully supported in the FXLN8362QR1 datasheet Rev 2.0.
Does FXLN8362QR1 require external decoupling capacitors, and if so, what values?
Yes, FXLN8362QR1 requires three external capacitors: a 100 nF ceramic capacitor between BYP and GND to stabilize the internal 1.5 V regulator; and 9.1 nF capacitors on XOUT, YOUT, and ZOUT to configure its low-bandwidth mode (1.1 kHz XY / 600 Hz Z). These values are specified in Table 5 of the FXLN8362QR1 datasheet and are mandatory for achieving rated bandwidth and noise performance.
How does the self-test function operate on FXLN8362QR1?
The FXLN8362QR1 self-test activates when the ST pin is driven logic high, applying an electrostatic actuation force to the MEMS sensor - simulating a known acceleration without mechanical stimulus. This produces a measurable output shift (35 mg on X/Y, 300 mg on Z) that verifies sensor integrity and analog signal chain functionality. The test is fully documented in Section 1.2 of the FXLN8362QR1 datasheet and requires no external equipment beyond a logic-level signal source.
What is the significance of the fixed 0.75 V zero-g output in FXLN8362QR1?
The FXLN8362QR1's fixed 0.75 V zero-g output is supply-independent - it remains stable across the full 1.71–3.6 V VDD range. This eliminates ratiometric errors common in analog sensors tied to VDD-referenced ADCs, simplifying signal conditioning and enabling accurate tilt or static acceleration measurement even with varying battery voltage. The specification is guaranteed over temperature (±45 mV) and is a core differentiator versus non-compensated accelerometers.
Can FXLN8362QR1 be used in automotive applications?
Yes, FXLN8362QR1 is qualified for operation from –40 °C to +105 °C and features 10,000 g shock survivability - meeting key environmental requirements for under-hood and cabin automotive subsystems such as seat position sensing, battery pack vibration monitoring, or ADAS-related motion feedback. While not AEC-Q200 certified, its thermal and mechanical specs align with many Tier-2 automotive use cases where full qualification is not mandated.
