Product details
Overview
LY530AL from STMicroelectronics is a single-axis MEMS yaw rate gyroscope delivering ±300°/s full-scale analog output and I²C/SPI digital output, operating from 2.7 V to 3.6 V with 4.8 mA analog supply current and 88 Hz −3 dB bandwidth at CACT = 10 nF, used in image stabilization for digital cameras and motion-controlled human-machine interfaces.
For engineers reviewing the LY530AL datasheet, LY530AL pinout, LY530AL application, or LY530AL equivalent, this page provides verified pin functions, real-world use scenarios, confirmed alternative parts with documented interface and sensitivity differences, and supply support for industrial embedded and consumer electronics design programs.
Technical Context
The LY530AL integrates a micromachined silicon sensing element with a CMOS interface IC, featuring dual-output architecture: absolute analog voltage output referenced to VDDA/2 (1.65 V zero-rate level) and configurable digital output via I²C or SPI with programmable low-pass and high-pass filters. Its PLL-based demodulation and active phase-switched filter enable stable rate measurement from DC to 88 Hz.
It supports embedded self-test (300 mV analog output shift), power-down mode (1 µA quiescent current), and operates across −40 °C to +85 °C. Digital output resolution is 1.55 LSB/°/s at 1 kHz ODR, with register-mapped control of filtering, output selection, and status monitoring.
Key Specifications

Pinout & Package
LY530AL uses a 5 mm × 5 mm × 1.5 mm LGA-16 package with exposed pad for thermal and mechanical stability. Pin assignment is validated per ST's official pin description table (Rev 1, p.7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 FILTVDD / VCONT | PLL filter connection | Set PLL loop dynamics; external RC network determines clock stability and jitter performance |
| 3 CACT | Active low-pass filter capacitor | Configures −3 dB bandwidth (e.g., 10 nF → 88 Hz); critical for noise vs. response trade-off |
| 4 ANALOG OUTPUT | Analog rate signal output | DC-coupled voltage output (0.4–2.9 V swing) with 1.65 V zero-rate offset; requires no external ADC |
| 6 GND | Ground reference | Common return for analog and digital sections; must be low-impedance to minimize crosstalk |
| 7 ST | Self-test control input | Logic high triggers internal mechanical excitation; verifies sensor integrity without external motion |
| 8 PD | Power-down enable | Logic high places device in 1 µA standby; essential for duty-cycled operation in portable systems |
| 9 SCL/SPC | I²C clock / SPI clock | Shared pin: SCL in I²C mode (max 400 kHz), SPC in SPI mode (max 10 MHz) |
| 10 CS | SPI chip select / I²C mode select | Low = SPI enabled; high = I²C enabled; determines interface protocol at power-up |
| 11 DR | DataReady indicator | Open-drain output pulses when new digital sample is ready; synchronizes host read timing |
| 13 SDA_SDI_SDO | I²C data / SPI input / 3-wire output | Tri-function pin: bidirectional I²C data, SPI SDI (4-wire), or SDO (3-wire); requires mode-aware routing |
| 14 Res | Internal pull-up enable | Must be tied to Vdd to activate internal pull-ups on CS, SCL/SPC, and SDA_SDI_SDO |
| 15 VDDD | Digital supply | Separate 2.7–3.6 V rail for digital logic and interface; decoupling required near pin |
| 16 VDDA | Analog supply | Independent 2.7–3.6 V rail for sensing and analog conditioning; isolation prevents digital noise coupling |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-axis yaw rate gyroscope applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LSM6DS3TR-C | 6-axis IMU (3-axis gyro + 3-axis accel); digital-only output; 110 Hz gyro BW; 1.8 V supply | Requires external processing for gyro-only use; lacks analog output and self-test voltage shift | Select when multi-axis fusion is needed and analog interface is unnecessary |
| ADXRS649 | Single-axis gyro; analog-only output; ±300°/s FS; 2.7–5.25 V supply; 120 Hz BW; higher noise floor (0.012°/s/√Hz) | No digital interface or embedded self-test; larger SOIC package (8.7 × 7.0 mm) | Select for legacy analog systems requiring wider supply range and higher bandwidth, accepting larger footprint |
Compared with LY530AL, LSM6DS3TR-C adds acceleration sensing but removes analog output and self-test voltage verification, while ADXRS649 offers higher bandwidth and supply flexibility but lacks digital configurability and compact LGA packaging.

FAQ
What is the function of the CACT pin on LY530AL?
The CACT pin connects an external capacitor (typically 10 nF) to set the −3 dB bandwidth of the analog low-pass filter. This capacitor directly determines the cutoff frequency-e.g., 10 nF yields 88 Hz-enabling designers to balance motion responsiveness against noise rejection without firmware changes or external op-amps.
How does the LY530AL self-test feature operate?
The ST pin triggers an internal electrostatic actuation that mechanically excites the MEMS structure, producing a calibrated 300 mV shift in the ANALOG OUTPUT voltage (or 230 LSB change in digital output). This verifies both sensor element integrity and analog/digital signal chain functionality without external motion or calibration fixtures.
Can LY530AL operate with only analog output enabled?
Yes. The analog output remains fully functional regardless of digital interface state. When CS is held high (I²C mode) and no I²C/SPI transactions occur, the device delivers continuous analog rate data with 1.65 V zero-rate level and 3.3 mV/°/s sensitivity, drawing only 4.8 mA-ideal for simple feedback loops without microcontroller overhead.
What is the significance of separate VDDA and VDDD pins?
VDDA powers the MEMS sensing element and analog signal conditioning circuitry, while VDDD supplies the digital interface and logic. This separation minimizes digital switching noise coupling into the sensitive analog path, preserving 0.8% full-scale nonlinearity and enabling reliable sub-degree-per-second resolution in electrically noisy environments.
