Programmable Audio Chip
The NV400F Programmable Audio Chip delivers 400-second voice storage with UART-updatable audio, 16-level volume control, and ultra-low 2μA shutdown. Featuring PWM audio output (drives 0.5W speakers directly!), wide voltage support (2.0V-5.5V), and 5 control modes. Perfect for smart home/medical devices needing frequent voice changes. Single-chip solution cuts costs and speeds production!
Ultra-Low Power, Field-Programmable Voice Solutions
Voice Integration with Dynamic Programmability
Meet the NV400F Programmable Audio Chip – the industry’s first Flash-based solution engineered for real-time voice flexibility. Designed for applications requiring frequent audio updates (≤400s), this chip eliminates complex hardware redesigns with UART/OTA reprogramming capabilities. From EV chargers guiding users via crystal-clear prompt to medical devices delivering life-critical alerts, NV400F transforms static audio into adaptive experiences.
Cutting-Edge Features
Engineered for performance and sustainability:
- Ultra-Low Power: 2μA soft-shutdown current extends battery life in portable devices (e.g., rehab tools, air purifiers).
- Studio-Grade Audio: 16KHz sampling rate & 32K PCM output with 16-level volume control ensure broadcast-quality playback.
- Seamless Control: Supports 5 control modes (UART, pulse, IO trigger) for effortless MCU integration.
- Zero-Cost Updates: Flash memory enables 1,000+ rewrite cycles – slash production costs and inventory waste.
Empower Your Products with Smarter Audio
Why developers choose NV400F:
✅ Scalable Production: Single-chip solution accelerates prototyping → mass production.
✅ Plug-and-Play: Directly drives 0.5W speakers via 12-bit PWM output – no external amps needed.
✅ Future-Proof: OTA upgrades let coffee machines, EV dashboards, and security systems evolve post-deployment.
✅ Rugged Reliability: 2.0-5.5V wide voltage operation survives unstable power environments.

Knowledge: Is programmable audio chip same with MTP sound chip?
🔹 What is a Programmable Sound Chip?
A programmable sound chip refers to a chip that allows custom sound files (like voice, music, alerts) to be written, erased, and rewritten—typically through a computer or programmer. It’s widely used in toys, greeting cards, promotional products, and smart home devices.
Key Features:
- User can upload custom audio (usually via USB or ISP programmer)
- Often supports multiple sound triggers (buttons, light, motion, etc.)
- Can store various lengths of audio depending on memory size
- Non-volatile memory—retains audio after power is off
🔹 What is an MTP Sound Chip?
MTP stands for Multi-Time Programmable. So an MTP sound chip is a type of programmable sound chip that allows the sound data to be programmed multiple times (but not unlimited like flash memory).
Key Features:
- Can be rewritten, usually up to 10–100 times
- Safer for production testing: you can reprogram if there’s a mistake
- Cheaper than full flash chips but more flexible than OTP (One-Time Programmable) chips
🔸 Summary of Differences
| Feature | Programmable Sound Chip | MTP Sound Chip |
|---|---|---|
| Definition | General term for any sound chip you can program | Specific type of programmable chip with limited reprogram cycles |
| Rewritable? | Yes | Yes (limited times) |
| Common Types | Flash, EEPROM, MTP, OTP | MTP only |
| Best For | Custom sound projects | Mid-volume production where small tweaks are still needed |
