SPM0204HD5

Overview

The SPM0204HD5 is a digital MEMS microphone manufactured by Syntiant. It utilizes PDM (Pulse Density Modulation) output technology for audio signal transmission. The device is designed for integration into compact electronic systems requiring high-fidelity sound capture with minimal power consumption.

Feature Summary

• Digital PDM interface for direct connection to processing units
• MEMS acoustic sensing structure for reliable audio capture
• Optimized form factor for space-constrained mobile applications

Applications

• Smartphones and tablets
• Voice-activated consumer electronics
• Wearable audio devices

Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the official Syntiant datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region and production batch.

Selection Notes

Select this component when a digital PDM output is required rather than analog. Ensure the host processor supports PDM clocking and data alignment specifications. Compare sensitivity and frequency response curves against system requirements to ensure adequate signal-to-noise ratio for the intended acoustic environment.

Part Context

This part belongs to Syntiant's portfolio of MEMS microphones, often integrated with neural processing solutions for always-on audio features. It complements the company's edge-AI hardware by providing the primary acoustic input stage for speech recognition and noise suppression tasks.

Replacement Considerations

Direct substitutes require matching PDM interface timing and physical footprint. Verify pin compatibility and acoustic performance metrics before swapping. Consult Syntiant documentation for approved alternative package options within the same product family.
