ISD1750PY01

Overview

The ISD1750PY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 series. It features user-selectable message durations ranging from 33 to 100 seconds, depending on the sampling frequency. The sampling rate can be adjusted between 4 kHz and 12 kHz using an external resistor. Operating voltage spans 2.4 V to 5.5 V. The device supports standalone push-button mode and SPI microcontroller mode. Key components include an on-chip oscillator, microphone preamplifier with Automatic Gain Control (AGC), auxiliary analog input, Multi-Level Storage (MLS) array, PWM Class D speaker driver, and configurable analog output.

Feature Summary

• Integrated message management system for standalone push-button applications
• Dual operating modes: Standalone and SPI interface control
• Direct drive capability via PWM Class D speaker output
• Configurable analog output for external amplifier driving

Applications

• Electronic systems requiring voice messaging
• Push-button controlled audio devices
• Microcontroller-based voice recording and playback systems

Procurement Notes

Verify the specific ordering suffix 'Y' indicates lead-free packaging as per the datasheet descriptor key. Confirm the 'P' suffix corresponds to the Plastic Dual Inline Package (PDIP). Ensure the '01' suffix matches the vAlert feature requirement if applicable. Cross-reference the manufacturer's current documentation for any specification updates or discontinuation notices before finalizing procurement.

Selection Notes

Select this component when a self-managing address location system for multiple messages is required without complex microcontroller logic. Choose based on the necessary message duration range of 33 to 100 seconds. Consider the dual output options: direct speaker drive via PWM or external amplification via analog output. Evaluate the need for SPI control versus simple push-button operation for the specific application design.

Part Context

The ISD1750 is part of the broader ISD1700 ChipCorder series, which utilizes patented Multi-Level Storage technology for solid-state memory storage. This series offers various message duration options, with the ISD1750 positioned in the mid-range capacity tier. The technology allows for high-quality voice reproduction without digital compression, distinguishing it from compressed audio solutions.

Replacement Considerations

Other models within the ISD1700 series offer different message durations. For shorter durations, consider the ISD1730 or ISD1740. For longer durations, the ISD1760, ISD1790, or higher variants may be suitable. All share similar pinouts and operational modes, facilitating potential drop-in replacements if duration requirements change.
