Product Overview
ISD 2560P ChipCorder is a single-chip voice record and playback integrated circuit designed for storing up to 60 seconds of natural analog audio. Manufactured by Information Storage Devices (ISD), later associated with Winbond and Nuvoton, this part is part of the original ChipCorder series that simplified voice-enabled product design. The 2560 designation indicates 60-second duration, and the “P” suffix confirms the 28-pin PDIP through-hole package. Audio is stored directly in non-volatile memory cells in analog form, eliminating the need for external ADCs, DACs, or battery backup circuits.
This architecture made the ISD2560P a practical choice for embedded voice prompts, alerts, and message playback in consumer and industrial electronics. With integrated microphone preamplifier, automatic gain control, filtering, and speaker driver, it reduces supporting component count in new builds or legacy repairs.

Frequently Asked Questions
Will this work as a drop-in replacement for other ISD2560 variants?
This is the PDIP-28 version (ISD2560P). It matches other 2560P package variants but should be verified against your board layout and control method.
How is audio stored on this chip?
Audio is stored directly in non-volatile analog memory cells rather than digitized and compressed. This was a defining feature of the ChipCorder series.
What voltage does it require?
Typical operating range is 4.5V to 5.5V. Confirm your circuit provides stable 5V logic-level power.
Has this unit been tested?
Visual inspection completed with no issues noted. As unused stock, it has not been installed or electrically tested.
How long is the recording duration?
The ISD2560P supports up to 60 seconds of total audio storage time.
ChipCorder parts helped put voices into toys, dashboards, and control panels long before digital modules became common. If you are keeping older hardware alive or building something that needs a real analog feel, this one is ready for its next circuit.
