ISD1760PYI01

Overview

The ISD1760PYI01 is a multi-message single-chip voice record and playback device from the ISD1700 series. It features 40 to 120 seconds of message duration depending on sampling frequency, which is adjustable from 4 kHz to 12 kHz via an external resistor. The device operates on a supply voltage ranging from 2.4 V to 5.5 V and supports both standalone push-button and SPI microcontroller modes. It includes an internal oscillator, microphone preamplifier with Automatic Gain Control (AGC), and a PWM Class D speaker driver. The part number suffix 'I' indicates industrial temperature range (-40°C to +85°C), 'Y' denotes lead-free packaging, and '01' specifies the vAlert feature.

Feature Summary

• Integrated message management system for self-managing address locations in standalone mode
• Dual operating modes: Standalone (push-button) and SPI microcontroller control
• Patented Multi-Level Storage (MLS) technology for non-volatile flash memory without digital compression
• vAlert feature for indicating new messages via external LED flashing

Applications

• Electronic systems requiring high-quality voice recording and playback
• Battery or line-powered applications utilizing low voltage operation
• Push-button controlled messaging devices
• Microcontroller-based voice interface systems

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, temperature rating, and special features like vAlert. Ensure compatibility with the required sampling frequency by selecting the appropriate external oscillator resistor value. Confirm lead-free status if environmental compliance is mandatory for the target application.

Selection Notes

Select the ISD1760 variant based on the required message duration and sampling frequency combination. Use the external resistor to set the desired sample rate between 4 kHz and 12 kHz. Choose the industrial temperature grade ('I') for environments exceeding commercial limits. Ensure the power supply voltage falls within the 2.4 V to 5.5 V range for proper operation.

Part Context

The ISD1760 belongs to the Winbond ISD1700 ChipCorder series, designed as fully integrated single-chip solutions for voice applications. This series utilizes proprietary MLS technology to store audio data directly in solid-state memory, eliminating the need for digital compression. The family supports various durations and packaging options to suit different electronic system requirements.

Replacement Considerations

Other members of the ISD1700 series such as ISD1730, ISD1740, ISD1750, ISD1790, etc., share similar functionality but offer different message durations. Verify pinout compatibility and software command sets when substituting with other series members.
