ISD17210X

Overview

The ISD17210X is a single-chip multi-message voice record and playback integrated circuit manufactured by Nuvoton Technology Corporation. This component is designed for applications requiring high-quality audio recording and reproduction within a compact form factor. It integrates necessary analog and digital circuits to facilitate direct microphone input and speaker output, eliminating the need for external codecs or complex interface logic. The device supports multiple message storage modes, allowing for flexible configuration of recording durations and playback sequences. Its architecture is optimized for low power consumption and ease of integration into embedded systems.

Feature Summary

• Integrates voice recording and playback functions on a single chip
• Supports direct connection to microphones and speakers without external codecs
• Enables flexible multi-message storage configurations
• Designed for low power operation in embedded applications

Applications

• Voice messaging devices
• Automated announcement systems
• Interactive toys and educational products
• Security alarm systems with voice alerts

Procurement Notes

Verify the specific suffix variant (e.g., EY01) against official Nuvoton datasheets to ensure compatibility with required package types and operating voltage ranges. Confirm that the source document explicitly lists the ISD17210X as an active product. Cross-reference pinouts and electrical specifications with the manufacturer's latest documentation to avoid integration errors due to revision changes.

Selection Notes

Select this component when a self-contained solution for short-duration voice recording and playback is required without external memory or processing overhead. It is suitable for designs prioritizing minimal bill of materials and simplified PCB layout. Evaluate power supply requirements and available GPIO pins to ensure the system can support the IC's control interface and audio I/O needs effectively.

Part Context

The ISD17210X belongs to Nuvoton's ISD series of voice record/playback ICs, which are widely used in consumer electronics and industrial controls. These components typically replace discrete solutions involving separate flash memory and audio processors, offering a cost-effective and space-saving alternative for voice-enabled applications.

Replacement Considerations

Consult Nuvoton's official substitution guide for compatible alternatives within the ISD family. Verify pin-to-pin compatibility and functional equivalence before replacing the ISD17210X with other models such as the ISD1700 series or newer variants.
