ISD2560PY

Overview

The ISD2560PY is a single-chip voice record and playback integrated circuit from Nuvoton's ChipCorder series, designed for multiple message applications with a recording duration of approximately 63.8 seconds. It utilizes CMOS technology and features an on-chip EEPROM storage array for non-volatile message retention without power. The device integrates essential audio processing components including a microphone preamplifier, automatic gain control, anti-aliasing filter, smoothing filter, and a speaker amplifier. It operates within a voltage range of 4.5 V to 6.5 V and supports pushbutton interface control. The component is housed in a 28-pin SOIC package.

Feature Summary

• Single-chip integration of voice recording, playback, and amplification functions
• On-chip non-volatile EEPROM memory for zero-power message storage
• Built-in analog signal conditioning including microphone preamp and automatic gain control
• Microcontroller-compatible interface allowing complex messaging addressing

Applications

• Pushbutton message cueing systems
• Multiple message announcement devices
• Consumer electronic voice prompts
• Industrial control audio signaling

Procurement Notes

Verify the specific suffix 'PY' against official Nuvoton documentation to confirm package type and temperature rating, as datasheets may list variants like SI or MT. Confirm RoHS compliance status, as some ISD25xx series listings indicate non-compliance. Check part status for obsolescence before procurement planning.

Selection Notes

Select this component for applications requiring simple pushbutton-controlled voice messages up to 64 seconds. Ensure the design accommodates the 4.5 V to 6.5 V supply requirement. Consider the 28-pin SOIC package dimensions for PCB layout. Verify if external microcontroller interfacing is needed for advanced addressing beyond basic pushbutton operation.

Part Context

The ISD2560PY belongs to the ISD2560/75/90/120 family of ChipCorder devices, which offer varying recording durations. These CMOS-based solutions replace older magnetic tape or discrete IC approaches by integrating all necessary audio and memory functions onto a single chip, simplifying system design for voice messaging products.

Replacement Considerations

Direct substitutes within the same series include ISD2560SI (SOIC-28) and ISD2560MT (TSSOP-28), offering identical functionality with different package footprints. For longer durations, consider ISD2575, ISD2590, or ISD25120 models.
