Overview
The ISD1760EYIR is a fully integrated single-chip multi-message voice record and playback device from the Nuvoton ISD1700 ChipCorder series. It features user-selectable message durations ranging from 26 to 120 seconds, with sampling frequencies adjustable between 4 kHz and 12 kHz via an external resistor. The device operates on a supply voltage of 2.4 V to 5.5 V and supports both standalone push-button and microcontroller SPI modes. Key internal components include an on-chip oscillator, microphone preamplifier with Automatic Gain Control (AGC), Multi-Level Storage (MLS) array, and a PWM Class D speaker driver.
Feature Summary
- Integrated message management system enabling self-managed address locations for multiple messages in a simple push-button environment.
- Dual operating modes allowing operation in standalone mode for automatic power-down or SPI mode for full microcontroller control.
- Proprietary Multi-Level Storage (MLS) technology providing non-volatile message storage without digital compression.
- Dual output channels consisting of a differential PWM Class D speaker driver and a configurable analog output.
Applications
- Electronic systems requiring high-quality voice recording and playback
- Battery-powered applications optimized for low voltage operation
- Line-powered electronic systems
- Push-button controlled messaging devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the component matches the required industrial or commercial specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select the ISD1760EYIR when message durations up to 120 seconds are required at lower sampling frequencies. Choose this model over others in the ISD1700 series based on the specific balance between recording duration and audio quality needed for the application. Consider the available packaging options such as SOIC or PDIP during the design phase.
Part Context
The ISD1760EYIR belongs to the Nuvoton ISD1700 ChipCorder series, which includes variants like the ISD1730 and ISD17120. These devices share common architectural features but differ in message duration capabilities. The series is designed for versatile integration into various electronic systems requiring reliable voice functionality.
Replacement Considerations
Compatible substitutes within the same family include the ISD1730SYI and ISD17120SYI. Selection depends on whether shorter or longer message durations are acceptable. Verify pin compatibility and electrical characteristics before substituting.
