ISD17240PY01

Overview

The ISD17240PY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 ChipCorder Series. It features an operating voltage range of 2.4V to 5.5V and supports selectable sampling frequencies from 4 kHz to 12 kHz, determined by an external oscillator resistor. The device provides a maximum message duration of 480 seconds at 4 kHz sampling. It incorporates Multi-Level Storage (MLS) technology for direct audio data storage in on-chip Flash memory without digital compression. The unit includes a differential microphone input with Automatic Gain Control (AGC), an auxiliary analog input, and dual output channels consisting of a PWM Class D speaker driver and a configurable analog output.

Feature Summary

• Integrated message management system enabling standalone push-button operation or microcontroller SPI control
• Dual operating modes: Standalone mode with automatic power-down and SPI mode for full user control via APC register
• Direct solid-state storage using Multi-Level Storage (MLS) technology for high-quality uncompressed audio reproduction
• Dual output capabilities including a PWM Class D speaker driver for direct 8Ω speaker connection and a configurable analog output

Applications

• Electronic systems requiring user-selectable message durations up to 480 seconds
• Battery-powered applications utilizing the wide 2.4V to 5.5V operating voltage range
• Devices requiring integrated voice recording and playback with minimal external components
• Applications needing both standalone push-button functionality and microcontroller-based SPI control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature rating, and lead-free status. The 'P' indicates a Plastic Dual Inline Package, 'Y' denotes lead-free construction, and 'I' signifies industrial temperature range. Confirm availability as specifications are subject to change without notice.

Selection Notes

Select this component when a long message duration up to 480 seconds is required. Ensure the external oscillator resistor value matches the desired sampling frequency between 4 kHz and 12 kHz. Verify that the 2.4V to 5.5V supply voltage aligns with the system design. Consider the 28-lead PDIP package dimensions if mechanical constraints require through-hole mounting.

Part Context

This part belongs to the Winbond ISD1700 ChipCorder Series, which offers various message durations ranging from 20 to 480 seconds. The series shares common architectural features such as MLS technology, AGC microphone preamplifiers, and dual output configurations. Other models in the series provide shorter durations or different package options while maintaining the same core voice recording and playback capabilities.

Replacement Considerations

ISD17210: Offers a maximum duration of 420 seconds. ISD17180: Provides a maximum duration of 360 seconds. ISD17150: Supports up to 300 seconds of recording time. These alternatives share the same interface and operational characteristics but differ in available message storage capacity.
