ISD17180SY01

Overview

The ISD17180SYI is a multi-message single-chip voice record and playback device from the Winbond ISD1700 ChipCorder series. It supports message durations of 120 to 360 seconds with user-selectable sampling frequencies ranging from 4 kHz to 12 kHz via an external oscillator resistor. The device operates on a supply voltage between 2.4 V and 5.5 V and features an internal oscillator, microphone preamplifier with Automatic Gain Control (AGC), and Multi-Level Storage (MLS) Flash memory for zero-power storage. It offers dual operating modes: standalone push-button control and microcontroller SPI interface. Audio inputs include differential microphone and single-ended analog paths, while outputs provide a PWM Class D speaker driver and configurable analog output.

Feature Summary

• Integrated message management system enabling standalone push-button operation with automatic power-down after each cycle.
• Dual input channels featuring differential microphone with AGC and single-ended auxiliary analog input.
• Dual output configuration with PWM Class D speaker driver and configurable current or voltage analog output.
• Optional vAlert feature allowing LED indication of new messages.

Applications

• Electronic systems requiring simple push-button voice messaging
• Microcontroller-based voice recording and playback applications
• Battery-operated devices utilizing low standby current

Procurement Notes

Verify component authenticity through authorized distributors as the part may be obsolete. Confirm package type and temperature grade against project requirements. Check for lead-free status if environmental compliance is mandatory. Ensure design compatibility with the specific ISD1700 series revision before procurement.

Selection Notes

Select based on required message duration and sampling frequency constraints. Choose industrial temperature range (-40°C to +85°C) for harsh environments. Verify package availability in SOIC, TSOP, or PDIP formats. Consider SPI mode requirements for complex message management versus standalone simplicity.

Part Context

The ISD17180SYI belongs to the Winbond ISD1700 ChipCorder series, designed for high-quality voice reproduction without digital compression. It utilizes patented Multi-Level Storage technology for direct audio data storage in solid-state memory. The series supports various message lengths and sampling rates, optimized for diverse electronic applications.

Replacement Considerations

The ISD17180SYI is obsolete. Recommended substitutes include I2361YYI and I3800FYI from Nuvoton Technology Corporation. Verify functional compatibility and pinout alignment when transitioning to these replacement parts.

FAQ

How is the sampling frequency adjusted?

The sampling frequency is adjustable from 4 kHz to 12 kHz by connecting an external resistor to the ROSC pin.

What are the two operating modes?

The device supports Standalone (Push-Button) mode for simple operations and SPI mode for full microcontroller control.

How does the vAlert feature work?

The vAlert feature flashes an external LED to indicate the presence of a new message.
