ISD2560E

Overview

The ISD2560E is a single-chip voice record and playback device from the ISD2500 series, manufactured by Nuvoton Technology Corporation. It provides approximately 60 seconds of recording duration using patented Direct Record to Flash (DRF) technology. The CMOS device integrates an on-chip oscillator, microphone preamplifier, automatic gain control, anti-aliasing filter, smoothing filter, speaker amplifier, and high-density multi-level storage array. Recordings are stored in non-volatile memory cells, enabling zero-power message storage. The component operates within a temperature range of -40 °C to 85 °C and is housed in a 28-pin SOIC package.

Feature Summary

• Integrates complete audio signal chain including microphone preamplifier, automatic gain control, and speaker amplifier on a single chip.
• Utilizes Direct Record to Flash technology for high-density multi-level storage without requiring external RAM or codecs.
• Features microcontroller-compatible interface allowing complex messaging and addressing logic.
• Provides zero-power message storage through non-volatile memory cells.

Applications

• Push button message cueing systems
• Automated voice prompts for consumer electronics
• Industrial equipment status announcements

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordered component matches the required operating temperature range and package type. Cross-reference the part number with official Nuvoton documentation to validate authenticity and revision level before integration into production designs.

Selection Notes

Select this component when a standalone voice solution is required without external memory or processing units. The ISD2560E is suitable for applications needing up to 60 seconds of continuous recording. Consider the integrated speaker amplifier capability if driving low-impedance loads directly. Verify interface compatibility with the host controller for address decoding and command execution.

Part Context

The ISD2560E belongs to the ISD2500 series of single-chip voice record/playback devices. This series offers various recording durations, including 60, 75, 90, and 120 seconds. The 'E' suffix typically denotes a specific package or temperature variant within the ISD2500 family, sharing core DRF technology with other models like the ISD2560I.

Replacement Considerations

Compatible substitutes include other members of the ISD2500 series such as the ISD2560I, ISD2575, ISD2590, and ISD25120, depending on required recording duration. Ensure the replacement maintains the same 28-pin SOIC package and microcontroller-compatible interface for direct pin-to-pin interchangeability.
