ISD17210SYI01

Overview

The ISD1700 Series is a fully integrated single-chip voice record and playback device utilizing Multi-Level Storage (MLS) technology. The ISD17210SYI variant provides selectable message durations ranging from 140 seconds to 420 seconds, depending on the sampling frequency set between 4 kHz and 12 kHz via an external resistor. Operating voltage spans 2.4 V to 5.5 V. It features dual input channels for differential microphone or analog signals, and dual outputs including a PWM Class D speaker driver and configurable analog output. The device supports standalone push-button operation and SPI microcontroller control modes.

Feature Summary

• Integrated message management system enabling standalone push-button operations with automatic power-down after each cycle.
• Dual operating modes: Standalone mode for simple applications and SPI mode for full microcontroller control and configuration.
• On-chip Flash memory storage without digital compression, ensuring high-quality natural voice reproduction.
• Built-in Automatic Gain Control (AGC) for microphone inputs and optional vAlert feature for new message indication.

Applications

• Electronic systems requiring multi-message voice prompts
• Industrial equipment status indicators
• Consumer appliances with voice feedback
• Security and alarm systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type, temperature rating, and special features such as vAlert support. Ensure compatibility with the required sampling frequency and message duration specifications for your application design.

Selection Notes

Select the ISD17210SYI when message durations between 140 and 420 seconds are required. Choose this model over other series variants based on the desired recording time versus sampling frequency trade-off. Confirm that the available packages (TSOP, SOIC, PDIP) fit the PCB layout constraints.

Part Context

The ISD17210SYI belongs to the Winbond ISD1700 ChipCorder Series, which offers high-quality, fully integrated voice recording solutions. This series is designed for various electronic systems needing flexible messaging capabilities with zero-power storage in Flash memory.

Replacement Considerations

Check for updated revisions within the ISD1700 series. Verify pinout and electrical characteristics if substituting with other ISD17xx models, as duration and package options vary across the family.
