ISD2560SY

Overview

The ISD2560SY is a speech synthesizer manufactured by Nuvoton Technology Corporation, designed for single-chip record and playback applications. It features an on-chip EEPROM storage array capable of retaining messages without power. The device supports a recording duration of approximately 63.8 seconds and operates within a commercial temperature range of -40 °C to 85 °C. It utilizes a 28-pin Plastic Dual Small Outline (PDSO-28) package with SOP body dimensions. The component integrates CMOS technology and includes internal circuitry such as oscillators, amplifiers, and filters necessary for voice processing.

Feature Summary

• Integrates high-density multi-level storage array for non-volatile message retention
• Includes built-in microphone preamplifier, automatic gain control, and anti-aliasing filter
• Compatible with microcontroller systems for complex addressing and messaging logic

Applications

• Push button message cueing systems
• Single-chip voice recording and playback devices
• Commercial integrated circuits requiring speech synthesis

Procurement Notes

Verify the specific suffix 'SY' against the manufacturer's official datasheet to confirm pinout compatibility and functional equivalence with other variants in the ISD2560 series. Ensure the procurement source provides documentation confirming the component meets the specified commercial temperature range and package standards. Cross-reference the ordering information with Nuvoton's current product listings to validate availability and revision status before finalizing orders.

Selection Notes

Select this component for applications requiring standalone speech synthesis with minimal external components. The integrated amplifier and filter reduce board space requirements compared to discrete solutions. Consider the 63.8-second duration limit when designing message sequences. Verify that the system voltage and interface requirements align with the CMOS specifications and microcontroller compatibility described in the technical data.

Part Context

The ISD2560SY belongs to the ISD ChipCorder series from Nuvoton, which provides single-chip record/playback solutions for messaging applications. This series is characterized by its ability to store recordings in on-chip nonvolatile memory cells, enabling zero-power message storage. The family typically includes variants with different recording durations, such as 60, 75, 90, and 120 seconds, catering to various consumer and commercial electronic needs.

Replacement Considerations

Check for other members of the ISD2560 series or the broader ISD ChipCorder lineup that may offer compatible pinouts or similar recording durations. Confirm if alternative suffixes denote only packaging or environmental differences rather than functional changes.
