ISD17150PY01

Overview

The ISD17150PY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 Series. It utilizes Multi-Level Storage (MLS) technology to store audio data directly in on-chip Flash memory without digital compression, ensuring high-quality voice reproduction. The device supports selectable sampling frequencies ranging from 4 kHz to 12 kHz via an external resistor, enabling message durations up to 300 seconds at lower sampling rates. Operating voltage spans 2.4 V to 5.5 V. It features dual input channels (differential microphone with AGC and auxiliary analog input) and dual output channels (PWM Class D speaker driver and configurable analog output). The unit operates in standalone push-button mode or microcontroller SPI mode.

Feature Summary

• Integrated message management system for standalone push-button applications with automatic power-down
• Dual operating modes including fully controllable SPI interface for microcontroller integration
• High-quality audio reproduction using patented Multi-Level Storage (MLS) technology without compression
• Flexible audio configuration with differential microphone inputs featuring Automatic Gain Control (AGC)
• Optional vAlert feature for visual indication of new messages via external LED

Applications

• Electronic greeting cards and toys
• Voice-enabled home appliances and security systems
• Industrial control panels and automated announcements
• Educational learning devices and language aids

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type, temperature rating, and lead-free status. The 'P' indicates PDIP packaging, 'Y' denotes lead-free composition, and 'I' specifies industrial temperature range. Confirm availability as this component may be subject to discontinuation or specification updates by the original manufacturer.

Selection Notes

Select based on required recording duration and sampling frequency constraints. Higher sampling frequencies provide better audio quality but reduce total recording time. Ensure the application environment falls within the specified commercial or industrial temperature ranges. Verify that the power supply voltage remains within the 2.4 V to 5.5 V operational limits for stable performance.

Part Context

This component belongs to the Winbond ISD1700 ChipCorder series, designed for versatile voice recording and playback applications. The series offers various duration options and packaging types to suit different product requirements. The ISD17150 variant specifically provides extended recording capabilities suitable for complex messaging sequences requiring longer audio segments.

Replacement Considerations

Direct replacements within the ISD1700 series include ISD17180, ISD17210, and ISD17240 for longer durations, or ISD1790 and ISD17120 for shorter durations. Cross-series replacement requires verification of pin compatibility and firmware logic differences between standalone and SPI modes.
