ISD2575P

Overview

The ISD2575P is a voice record and playback integrated circuit manufactured by Nuvoton Technology Corporation. It features an internal oscillator and supports up to 75 seconds of recording time. The device utilizes Automatic Gain Control (AGC) for audio processing. It operates within a temperature range of 0°C to 70°C (TA). The component is housed in a 28-DIP package.

Feature Summary

• Supports pushbutton operation for message recording and playback
• Integrates Automatic Gain Control for consistent audio levels

Applications

• Voice messaging systems
• Automated announcement devices
• Interactive voice response units

Procurement Notes

Verify the current status of the ISD2575P, as it may be discontinued or subject to supply constraints. Confirm RoHS compliance requirements, noting that some sources indicate lead content. Ensure the 28-DIP package matches your PCB footprint before ordering. Check for available substitutes from the ISD2560/75/90/120 series if this specific part is unavailable.

Selection Notes

Select the ISD2575P when a dedicated voice solution with approximately 75 seconds of capacity is required. Consider the 28-DIP package for through-hole assembly needs. Evaluate the internal oscillator requirement against external clock precision needs. Verify that the operating temperature range of 0°C to 70°C meets your environmental specifications.

Part Context

This component belongs to the ISD2560/75/90/120 family of voice ICs. These parts are designed for simple voice recording and playback applications without requiring complex microcontroller interfaces. The ISD2575P specifically offers a mid-range storage capacity within this lineup, suitable for fixed-length messages.

Replacement Considerations

Check for other members of the ISD2560/75/90/120 series for potential pin-compatible alternatives with different recording times. Verify if newer generations from Nuvoton offer equivalent functionality with updated compliance standards.
