ISD1760SYI01

Overview

The ISD1760SYI01 is a multi-message single-chip voice record and playback device from the ISD1700 series. It features user-selectable message durations ranging from 40 to 120 seconds, determined by an external oscillator resistor that sets the sampling frequency between 4 kHz and 12 kHz. The device operates on a supply voltage of 2.4 V to 5.5 V and supports both standalone push-button and SPI microcontroller modes. Key electrical parameters include a typical standby current of 1 µA, speaker output power up to 670 mW at 5.5 V into an 8 Ω load, and total harmonic distortion of 1%. It utilizes patented Multi-Level Storage (MLS) technology for non-volatile audio data storage.

Feature Summary

• Integrated message management system enabling self-managed address locations for multiple messages in standalone mode.
• Dual operating modes allowing operation via simple push-button controls or full microcontroller control through a 4-wire SPI interface.
• Patented Multi-Level Storage (MLS) technology providing high-quality, uncompressed voice and music reproduction without digital compression artifacts.
• Built-in Automatic Gain Control (AGC) microphone preamplifier with dual input paths for differential microphone or single-ended analog signals.

Applications

• Electronic greeting cards and toys requiring simple push-button voice interaction.
• Industrial and commercial automated announcements using microcontroller-based SPI control.
• Security systems and alarm devices utilizing vAlert functionality for new message indication.
• Educational learning aids and interactive manuals featuring sequential message playback.

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 the component meets the required environmental specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this device when applications require flexible message duration versus quality trade-offs achievable through external resistor configuration. Consider the ISD1760SYI01 for designs needing integrated volume control, LED indicators, and automatic power-down capabilities to optimize battery life in portable electronic systems.

Part Context

This component belongs to the ISD1700 ChipCorder series, which offers a range of message durations from 20 seconds to 480 seconds depending on the specific model variant. The series is characterized by its fully integrated single-chip solution that eliminates the need for external memory or complex audio processing circuits, simplifying design implementation.

Replacement Considerations

Other models within the ISD1700 series, such as the ISD1730, ISD1740, or ISD1750, offer different duration ranges but share similar pinouts and operational modes. Verify compatibility regarding message duration requirements and ensure that any substitute part maintains the necessary voltage and temperature specifications for the target application.
