ISD1760PY01

Overview

The ISD1760PY01 is a multi-message single-chip voice record and playback device from the Winbond ISD1700 series. It features user-selectable message durations ranging from 40 to 120 seconds, depending on the sampling frequency. The device supports operating voltages between 2.4 V and 5.5 V and operates within an industrial temperature range of -40 °C to +85 °C. It utilizes Multi-Level Storage (MLS) technology for direct audio data storage in on-chip Flash memory without digital compression. The component includes an integrated microphone preamplifier with Automatic Gain Control (AGC), a PWM Class D speaker driver, and configurable analog outputs.

Feature Summary

• Integrated message management system enabling standalone push-button operation or microcontroller SPI control
• Dual input channels supporting differential microphone signals with AGC and single-ended auxiliary analog inputs
• Dual output capabilities including a PWM Class D speaker driver and configurable current/voltage analog outputs
• Optional vAlert feature providing visual indication of new messages via external LED flashing

Applications

• Electronic greeting cards and toys requiring simple voice recording and playback
• Industrial and commercial voice prompts controlled by microcontrollers
• Security systems utilizing voice alerts and status indicators
• Consumer appliances featuring recorded instructions or alarms

Procurement Notes

Verify the specific suffix 'Y' indicates lead-free packaging compliance as defined in the ordering information section. Confirm the 'P' package designation corresponds to the Plastic Dual Inline Package (PDIP). Ensure the '01' special feature code matches the required vAlert functionality. Cross-reference the datasheet revision date against manufacturing dates to confirm specification accuracy.

Selection Notes

Select this model when a recording duration between 40 and 120 seconds is required. Choose based on the necessary sampling frequency to balance audio quality against total message length. Verify that the industrial temperature rating meets environmental requirements. Ensure the system design accommodates the 28-pin PDIP footprint and power supply constraints.

Part Context

This component belongs to the Winbond ISD1700 ChipCorder series, which provides fully integrated voice recording solutions. The series differentiates models primarily through selectable message duration ranges determined by internal memory capacity and sampling rates. The ISD1760 represents a mid-range duration option within this family, suitable for applications needing moderate message lengths.

Replacement Considerations

ISD1750: Offers shorter duration ranges (33-100 seconds). ISD1790: Provides longer duration ranges (60-180 seconds). Both share identical pinouts and operational modes but differ in memory capacity and timing parameters.
