STMicroelectronics LPY530AL

Overview

LPY530AL from STMicroelectronics is a dual-axis MEMS gyroscope measuring angular rate along pitch and yaw axes with ±300°/s full-scale range, 140 Hz bandwidth, and analog outputs (amplified and non-amplified) for each axis. It operates from 2.7 V to 3.6 V, delivers 3.33 mV/°/s sensitivity on 4× outputs, and supports industrial motion sensing in GPS navigation, robotics, and game controllers.

For engineers reviewing the LPY530AL datasheet, LPY530AL pinout, LPY530AL application, or LPY530AL equivalent, this page provides verified mechanical and electrical specifications, LGA-16 package layout, self-test and power-down functionality, temperature-stable analog output behavior, and real-world integration guidance for motion control systems.

Technical Context

The LPY530AL integrates a single micromachined driving mass and Coriolis-based sensing element with a dedicated CMOS interface IC. Its dual-output architecture provides separate 1× and 4× amplified analog voltage signals per axis (X and Z), enabling flexible signal chain design without external gain stages.

It embeds low-pass filtering (140 Hz −3 dB bandwidth), high-pass filter reset (HP pin), PLL synchronization circuitry requiring external RC components on FILTVDD/VCONT pins, and factory-trimmed reference voltage (1.23 V) for zero-rate stability across −40°C to +85°C.

Key Specifications

Pinout & Package

FAQ

What is the purpose of the HP pin on the LPY530AL?

The HP (High Pass Filter Reset) pin resets external high-pass filter capacitors to prevent output saturation during rapid angular transients or power-up. When driven logic-high, it discharges the HP capacitor, restoring baseline tracking capability-critical for maintaining accuracy after large rotations or system wake-up.

How does the self-test function verify sensor integrity?

The ST pin activates an internal electrostatic force that displaces the micromachined driving mass, generating a known Coriolis-like output shift (~1.0 V change on 4× outputs). Measuring this predictable voltage step confirms both mechanical resonance and analog signal path functionality without physical motion or external test equipment.

Why are there two output types (OUTX/OUTZ and 4xOUTX/4xOUTZ)?

The dual-output architecture supports different signal chain strategies: non-amplified outputs (0.83 mV/°/s) suit applications needing wide dynamic range (±1200°/s), while 4× amplified outputs (3.33 mV/°/s) provide higher resolution for ±300°/s motion capture-enabling flexible design without external gain stages or trade-offs in ADC resolution.

What external components are required for basic LPY530AL operation?

Minimum external components include: 100 nF + 10 µF decoupling capacitors on Vdd, 10 kΩ resistor and 470 nF capacitor on FILTVDD/VCONT for PLL loop filtering, and pull-down resistors on ST/PD/HP control pins. Amplified outputs require no additional buffering; non-amplified outputs benefit from external gain or reference-biasing at 4xINX/4xINZ.
