ISD2560SYR Equivalent & Substitute Parts

Part Overview

The ISD2560SYR is a voice record/playback IC from Nuvoton Technology Corporation's ChipCorder® series, designed for single-message applications with 1-minute recording duration. This component integrates analog microphone input, pushbutton interface control, and PWM speaker output in a 28-SOIC surface mount package. The product is currently obsolete, making equivalent substitutes necessary for new designs or system maintenance requiring active component sourcing.

Substitute Part Grouping Explanation

The ISD1760SY qualifies as a manufacturer-recommended substitute for the ISD2560SYR based on the following substitution criteria:

Mechanical Compatibility: Both components use identical 28-SOIC surface mount packaging (0.295", 7.50mm width), enabling direct PCB footprint compatibility without layout modifications.

Functional Compatibility: Both devices are ChipCorder® series voice record/playback ICs with multiple-message capability, analog microphone input, and pushbutton interface control. Both support PWM speaker output and automatic gain control features.

Electrical Operating Range: The ISD1760SY supply voltage range (2.4 V ~ 5.5 V) encompasses the ISD2560SYR requirement (4.5 V ~ 5.5 V), ensuring operation within the original design voltage specification. Both operate across the same temperature range (0°C ~ 70°C).

Signal Compatibility: Both accept analog single-ended microphone input and deliver PWM speaker output, maintaining signal interface consistency.

Key Differentiators: The ISD1760SY extends recording duration to 40 ~ 120 seconds (versus 1 minute fixed), offers adjustable sampling frequency (4 ~ 12kHz versus fixed 8kHz), includes SPI interface capability, and provides volume control. The ISD1760SY is active product status with ROHS3 compliance, whereas the ISD2560SYR is obsolete.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The ISD1760SY is the manufacturer-recommended substitute for the obsolete ISD2560SYR. Both components share identical 28-SOIC packaging and core functional architecture, supporting direct PCB substitution without layout redesign.

Product Status Consideration: The ISD2560SYR is obsolete with no active manufacturing. The ISD1760SY is active product status, ensuring long-term component availability and supply chain reliability for new designs or production restarts.

Compliance Status: The ISD1760SY carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both components maintain REACH Unaffected and EAR99 export classification status.

Voltage Supply Flexibility: The ISD1760SY's extended supply voltage range (2.4 V ~ 5.5 V) provides design flexibility beyond the ISD2560SYR specification (4.5 V ~ 5.5 V), enabling operation in lower-voltage applications while maintaining compatibility with 5V designs.

Moisture Handling: The ISD2560SYR specifies MSL 1 (unlimited moisture sensitivity), while the ISD1760SY specifies MSL 3 (168-hour limit). Storage and handling procedures must align with the ISD1760SY moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the ISD1760SY replace the ISD2560SYR in existing designs?

A: Yes. Both components use identical 28-SOIC packaging and support the same core interfaces (pushbutton control, analog microphone input, PWM speaker output). No PCB modifications are required for mechanical or electrical compatibility within the specified voltage range (4.5 V ~ 5.5 V).

Q: What are the key functional differences between these parts?

A: The ISD1760SY extends recording duration to 40 ~ 120 seconds with adjustable sampling frequency (4 ~ 12kHz), adds SPI interface capability, includes volume control, and supports lower supply voltages (2.4 V minimum). The ISD2560SYR provides fixed 1-minute duration at 8kHz sampling with pushbutton interface only.

Q: Are there supply chain advantages to using the ISD1760SY?

A: Yes. The ISD1760SY is active product status with 3504 units in stock, while the ISD2560SYR is obsolete. Active manufacturing ensures component availability for production quantities and future orders.

Q: Does the ISD1760SY require different PCB layout considerations?

A: No. Both components use identical 28-SOIC (0.295", 7.50mm width) surface mount packaging. Existing PCB footprints and layouts are directly compatible without modification.

Q: What moisture sensitivity precautions apply to the ISD1760SY?

A: The ISD1760SY specifies MSL 3 (168-hour moisture absorption limit), requiring controlled storage conditions and handling procedures. The ISD2560SYR specifies MSL 1 (unlimited), so storage protocols must be updated to meet the stricter ISD1760SY requirement.

Q: Is the ISD1760SY suitable for designs requiring fixed 1-minute recording duration?

A: Yes. The ISD1760SY supports 40 ~ 120-second recording duration, which encompasses the 1-minute (60-second) requirement. Firmware or hardware configuration can be set to achieve the required duration within this range.

Q: Are both components compliant with current environmental regulations?

A: Yes. Both maintain REACH Unaffected status and EAR99 export classification. The ISD1760SY additionally carries ROHS3 compliance certification, meeting current environmental standards.
