Q: What's the difference between OTP and Programmable Voice Chips?

OTP (One-Time Programmable) uses mask ROM — cost-effective for high-volume products with fixed audio. Programmable uses Flash memory — update audio anytime via PC tool, ideal for prototyping. Choose OTP for >10K volume, Programmable for flexibility or lower volume.

Q: How do I select the right voice IC for my application?

Consider: (1) Audio duration needed (6s-680s for prompts, MicroSD for music), (2) Interface type (I/O trigger, SPI, UART), (3) Power budget (battery vs. mains), (4) Production volume. Contact our engineers with your requirements for chip selection guidance.

Q: What is WayTronic's MOQ and sampling policy?

Free samples available with 3-day delivery for prototyping. MOQ varies by model: Programmable chips 100-500pcs, OTP chips 3K-10K pcs, MP3/Bluetooth ICs 100-1K pcs. Submit a quote request with your model and quantity — we respond within 8 hours.

Q: Do WayTronic voice ICs work with Arduino and Raspberry Pi?

Yes! Our ICs support standard UART/SPI/I2C interfaces compatible with Arduino, Raspberry Pi, ESP32, and other development boards. We provide Arduino libraries, Python examples, datasheets with timing diagrams, and reference schematics in our Resources section.
