Product details
Overview
LPR410AL from STMicroelectronics is a dual-axis analog MEMS gyroscope measuring angular rate along pitch and roll axes, with ±100 dps full-scale range, 140 Hz bandwidth, and analog outputs (amplified and non-amplified) for both axes-used in motion-controlled user interfaces and GPS navigation systems.
For engineers reviewing the LPR410AL datasheet, LPR410AL pinout, LPR410AL application, or LPR410AL equivalent, key selection considerations include its dual-output architecture (1×/4×), embedded self-test and sleep mode, temperature-stable zero-rate level (±0.03 dps/°C), and LGA-28 package compatibility with industrial motion sensing designs.
Technical Context
The LPR410AL integrates a single micromachined driving mass operating on the Coriolis principle, coupled with a CMOS interface IC that conditions and outputs analog voltage signals proportional to angular rate. Its sensing element is fabricated using ST's mature plastic LGA accelerometer process.
It features two independent analog output paths per axis (OUTX/OUTY and 4xOUTX/4xOUTY), integrated low-pass filtering (140 Hz −3 dB), optional external high-pass filter reset via HP pin, and configurable operating modes (normal, sleep, power-down, self-test) controlled by ST and SLEEP/PD pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full Scale Range | ±100 dps (4xOUT) / ±400 dps (OUT) - defines measurable angular rate limits before saturation |
| Sensitivity | 10 mV/dps (4xOUT) / 2.5 mV/dps (OUT) - determines output voltage per unit rotation rate |
| Bandwidth | 140 Hz (−3 dB) - supports real-time motion tracking up to rapid hand gestures or vehicle yaw |
| Zero-Rate Level | 1.5 V ±0.03 dps/°C drift - provides stable DC reference for rate measurement at rest |
| Supply Voltage | 2.7–3.6 V - compatible with standard 3.3 V embedded systems without level-shifting |
| Operating Temp | −40 °C to +85 °C - validated for automotive cabin and industrial indoor environments |
| Self-Test Output Δ | 250 mV typical - enables in-system verification of mechanical integrity and signal chain |
Pinout & Package
LPR410AL is housed in a 4 mm × 5 mm × 1 mm plastic land grid array (LGA-28) package, optimized for surface-mount assembly and mechanical shock survivability (up to 3000 g).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 20 | OUTX / OUTY | Non-amplified analog angular rate outputs (2.5 mV/dps sensitivity) |
| 5, 16 | 4xINX / 4xINY | Inputs to internal 4× amplifiers - must be tied to Vref if non-amplified outputs used |
| 7, 14 | 4xOUTX / 4xOUTY | Amplified analog outputs (10 mV/dps sensitivity, low-impedance buffered) |
| 9, 19 | Vdd | Main 2.7–3.6 V supply - requires local 100 nF + 10 µF decoupling |
| 22 | Vref | 1.5 V internal reference - used to bias amplifier inputs and stabilize zero-rate level |
| 24 | HP | High-pass filter reset control - logic high resets external HP filter for fast recovery after overload |
| 26 | GND | 0 V reference plane - must be connected to solid ground plane for noise immunity |
| 27 | ST | Self-test activation - logic high applies electrostatic force to verify sensor mass movement |
| 28 | SLEEP/PD | Mode control - low = normal, high = power-down; combined with ST selects sleep/self-test |
Key Features
| Feature | Design Value |
|---|---|
| Dual-axis analog output architecture | Separate 1× and 4× amplified outputs per axis enable flexible gain selection without external op-amps |
| Embedded self-test | Electrostatic actuation verifies mechanical integrity and signal chain functionality in-system without motion |
| Configurable low-power modes | Power-down (5 µA), sleep (2.1 mA), and normal (6.8 mA) modes support battery-constrained portable devices |
| Temperature-stable zero-rate level | Drift ≤0.03 dps/°C ensures minimal calibration burden across −40 °C to +85 °C operation |
| Integrated PLL-based drive circuit | Stabilizes oscillation frequency of micromachined mass, improving long-term bias stability |
Applications
| GPS Navigation Systems | Motion Tracking |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-axis analog gyroscope applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXRS645 | Single-axis, digital SPI output; higher bandwidth (3.3 kHz); wider temp range (−40 °C to +105 °C) | Requires external ADC and digital interface design; better suited for high-dynamic industrial stabilization | Select when system demands digital interface, higher bandwidth, or extended temperature operation |
| LPY410AL | Single-axis (yaw-only); identical analog architecture, LGA-28 package, and pinout except axis orientation | Not interchangeable without PCB redesign; suitable only where single-axis yaw sensing suffices | Select only for yaw-only applications requiring footprint and interface compatibility |
Compared with ADXRS645 and LPY410AL, the LPR410AL uniquely delivers dual-axis analog outputs in one LGA-28 package with embedded self-test and configurable gain-making it optimal for cost-sensitive, space-constrained motion UIs needing no digital interface overhead.

FAQ
What is the function of the HP pin on the LPR410AL?
The HP (High-Pass Filter Reset) pin resets an optional external high-pass filter by applying logic high. This clears DC offset buildup after large angular transients or power-up, ensuring accurate baseline restoration within milliseconds. It is recommended to assert HP during initialization and after overload events to maintain measurement fidelity.
How do I configure the LPR410AL for power-down mode?
Drive the SLEEP/PD pin high (≥0.8×Vdd) while keeping ST low (≤0.2×Vdd). In this state, supply current drops to 5 µA and all analog outputs go to high-impedance. The device retains configuration but requires ~10 ms wake-up time to resume normal operation upon returning SLEEP/PD to low.
Can I use only the amplified outputs (4xOUTX/4xOUTY) without connecting 4xINX/4xINY?
No. Pins 5 (4xINX) and 16 (4xINY) must be shorted to pins 1 (OUTX) and 20 (OUTY), respectively, when using amplified outputs. Leaving them floating causes undefined gain behavior. If non-amplified outputs are used instead, tie 4xINX/4xINY to Vref (pin 22) to disable amplification.
What is the purpose of the VCONT and FILTVDD pins?
VCONT and FILTVDD form part of an external RC low-pass filter for the internal PLL circuit that drives the micromachined mass. Per Figure 3 in the datasheet, connect a resistor (2.2 kΩ) between VCONT and FILTVDD, and a capacitor (100 nF) from FILTVDD to GND to stabilize oscillator phase noise and ensure consistent resonance frequency.
