STMicroelectronics LPY510AL

Overview

LPY510AL from STMicroelectronics is a dual-axis MEMS analog gyroscope measuring angular rate along pitch and yaw axes, with ±100°/s full-scale range, 140 Hz bandwidth, 10 mV/°/s sensitivity on amplified outputs, and operation from -40°C to +85°C. It delivers absolute analog rate output via two independent axis channels (X and Z), each with both non-amplified and 4× amplified outputs, for motion tracking in GPS navigation and pointing devices.

For engineers reviewing the LPY510AL datasheet, LPY510AL pinout, LPY510AL application, or LPY510AL equivalent, this page provides verified mechanical and electrical specifications, LGA-16 package layout, self-test and power-down functionality, integrated low-pass filtering, and real-world use cases in robotics, remote controllers, and industrial motion control systems.

Technical Context

The LPY510AL integrates a single micromachined driving mass operating under Coriolis principle detection, paired with a dedicated CMOS interface IC that conditions and outputs analog voltage signals. Its sensing element is factory-trimmed for stability across temperature, with zero-rate level at 1.23 V and minimal drift (0.02 °/s/°C).

It features embedded PLL-based drive-sense synchronization, configurable external high-pass filter reset (HP pin), dual gain paths (1× and 4×), and internal low-pass filtering capped at 140 Hz. Power management includes logic-controlled power-down mode drawing only 1–5 µA and self-test activation via ST pin.

FAQ

What is the function of the HP pin on the LPY510AL?

The HP (High-Pass Filter Reset) pin is a logic-controlled terminal that resets external high-pass filter capacitors when driven high. This action clears DC offset buildup during overload or power-up transients, ensuring rapid stabilization of the output baseline. It is recommended to assert HP high briefly at power-on and after large rotational events to maintain accurate zero-rate tracking.

Can the LPY510AL operate from a 3.3 V supply?

Yes-the LPY510AL is fully specified for 2.7 V to 3.6 V operation, making 3.3 V an optimal supply voltage. At 3.3 V, it draws 6.8 mA in active mode and maintains full performance including 10 mV/°/s sensitivity, 1.23 V Vref, and -40°C to +85°C operation without derating. Decoupling with 100 nF ceramic + 10 µF aluminum capacitors is mandatory per ST's layout guidance.

How does the self-test feature verify sensor functionality?

The self-test applies an electrostatic force to the micromachined driving mass via the ST pin, emulating a known Coriolis acceleration. When activated, it induces a predictable DC-level shift in both 4xOUTX and 4xOUTZ outputs-typically ~100 mV-verifying mechanical mobility and analog signal chain integrity. No external rotation or test equipment is needed, enabling in-field diagnostics without removing the device from the PCB.

Why are pins 14 and 15 labeled "Res" and tied to Vdd?

Pins 14 and 15 are reserved internal test or configuration nodes not intended for user connection. ST specifies they must be externally connected to Vdd to ensure proper internal biasing and functional stability. Leaving them floating or grounding them may cause undefined behavior, increased noise, or failure to meet datasheet specifications for zero-rate level and sensitivity consistency.
