ISD2560P

Overview

The ISD2560P is a single-chip voice record and playback integrated circuit from the ChipCorder series, manufactured by Nuvoton Technology Corporation. It provides 60 seconds of recording duration with a sampling frequency of 5.3 kHz and a pass band of 2.3 kHz. The device operates on a supply voltage of 4.5 V to 6.5 V and features an internal oscillator. It utilizes pushbutton interface control and outputs PWM signals for speaker connection. The component is housed in a 28-DIP package with a width of 0.600 inches (15.24 mm) and supports through-hole mounting. Operating temperature ranges from 0°C to 70°C.

Feature Summary

• Integrates microphone preamplifier, automatic gain control, anti-aliasing filter, smoothing filter, and speaker amplifier on a single chip.
• Stores recordings in on-chip nonvolatile memory cells, enabling zero-power message storage without battery backup.
• Microcontroller-compatible interface allows for complex messaging and addressing logic implementation.

Applications

• Pushbutton-controlled voice message cueing systems
• Multiple message announcement devices
• Single-chip record/playback solutions for short-duration audio

Procurement Notes

Verify component status as the ISD2560P is listed as obsolete by the manufacturer. Confirm RoHS compliance status, which is indicated as non-compliant in available records. Ensure the 28-DIP package availability aligns with current production constraints. Validate that the 4.5 V to 6.5 V supply requirement matches the target system design before procurement.

Selection Notes

Select this component for applications requiring simple pushbutton operation and up to 60 seconds of high-quality voice storage. Consider the 5.3 kHz sampling rate and 2.3 kHz pass band for speech clarity requirements. Evaluate the 28-DIP package suitability for through-hole PCB layouts. Compare against other durations in the ISD2560/75/90/120 series if longer recording times are needed.

Part Context

The ISD2560P belongs to the ISD ChipCorder series, which offers single-chip CMOS voice record/playback solutions. This series includes variants with 60, 75, 90, and 120-second durations. All devices share common features such as on-chip oscillators, microphones preamps, and nonvolatile memory storage, providing a unified platform for voice messaging applications.

Replacement Considerations

Check for newer generations of voice record/playback ICs from Nuvoton or other manufacturers. Verify pin compatibility if substituting with other ISD series parts like ISD2570P or ISD2590P, noting differences in recording duration and package types.
