ISD17180PYI01

Overview

The ISD17180PYI01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 series. It features an operating voltage range of 2.4V to 5.5V and supports industrial temperature operation from -40°C to +85°C. The device provides a maximum message duration of 360 seconds at a 4 kHz sampling frequency, with selectable frequencies between 4 kHz and 12 kHz determined by an external resistor. It utilizes Multi-Level Storage (MLS) technology for direct audio data storage in on-chip Flash memory without digital compression. The component includes a differential microphone input with Automatic Gain Control, auxiliary analog input, PWM Class D speaker driver, and SPI interface.

Feature Summary

• Integrated message management system enabling standalone push-button operation or microcontroller-controlled SPI mode
• Dual output channels consisting of a PWM Class D speaker driver and configurable analog current/voltage output
• On-chip oscillator with external resistor control allowing user-selectable sampling frequencies
• Automatic power-down capability after each operation cycle for power conservation

Applications

• Electronic systems requiring high-quality voice messaging
• Battery-powered applications due to wide voltage support and low standby current
• Industrial environments requiring extended temperature range operation
• Devices utilizing vAlert feature for new message indication

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature rating, and lead-free status. Ensure compatibility with the required message duration and sampling frequency settings before procurement. Confirm availability through authorized distributors as specifications are subject to change without notice.

Selection Notes

Select this model when a maximum recording time of 360 seconds at 4 kHz is required. Choose based on the need for industrial temperature ratings (-40°C to +85°C) and the 28-lead PDIP package configuration. Consider the ISD1700 series variants if different duration requirements or commercial temperature ranges are sufficient for the application.

Part Context

The ISD17180 is part of the Winbond ISD1700 ChipCorder series, which offers various message durations ranging from 20 to 480 seconds. This specific variant provides the longest duration within the standard series lineup. The series is designed for applications needing flexible voice recording and playback capabilities with simple interface options.

Replacement Considerations

Other models within the ISD1700 series offer different message durations but share similar pinouts and operational modes. Verify that alternative parts meet the specific 360-second duration requirement and industrial temperature specifications before substitution.

FAQ

How is the sampling frequency adjusted on the ISD17180?

The sampling frequency is controlled by an external resistor connected to the ROSC pin. The value of this resistor determines the frequency, which can be set between 4 kHz and 12 kHz.

What is the function of the vAlert feature?

The vAlert feature allows the device to flash an external LED to indicate the presence of a new message, providing a visual notification mechanism.

Can the ISD17180 operate without a microcontroller?

Yes, the device supports a Standalone (Push-Button) mode where operations like record, play, erase, and forward are initiated directly via hardware buttons without microcontroller intervention.
