Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISD1760EY is determined by strict equivalence across the following critical parameters:

• Functional capability: Voice record/playback IC with multiple message support
• Interface compatibility: Pushbutton and SPI control
• Signal characteristics: Analog single-ended microphone input and PWM speaker output
• Sampling frequency range: 4–12 kHz
• Recording duration: 40–120 seconds
• Supply voltage range: 2.4 V–5.5 V
• Operating temperature range: 0°C–70°C
• Oscillator type: Internal
• Integrated features: Automatic gain control and volume control
• Mounting technology: Surface mount
• Manufacturer: Nuvoton Technology Corporation
• Series: ChipCorder®

The ISD1760SY meets all these criteria and is identified as a manufacturer-recommended substitute. The primary difference is the package type: the ISD1760EY uses 28-TSOP packaging, while the ISD1760SY uses 28-SOIC packaging. Both packages are surface-mount technologies with compatible pin counts and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ISD1760SY is the manufacturer-recommended substitute for the ISD1760EY. Both components share identical electrical specifications, functional capabilities, and compliance certifications. The ISD1760SY holds active product status, ensuring ongoing availability and support from Nuvoton Technology Corporation.

The primary consideration for substitution is package compatibility. The ISD1760EY uses 28-TSSOP packaging (11.80mm width), while the ISD1760SY uses 28-SOIC packaging (7.50mm width). PCB layout modifications are required to accommodate the different package footprints. Both packages maintain 28-pin configurations with equivalent pin assignments for voice record/playback functionality.

The ISD1760SY is ROHS3 compliant, providing enhanced environmental compliance compared to the obsolete ISD1760EY. Both components maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the ISD1760SY directly replace the ISD1760EY without PCB modifications?

A: No. While the electrical specifications and pin counts are identical, the package types differ. The ISD1760EY uses 28-TSSOP packaging and the ISD1760SY uses 28-SOIC packaging. PCB footprint redesign is required for substitution.

Q: Are the pin assignments identical between ISD1760EY and ISD1760SY?

A: Yes. Both devices maintain equivalent pin assignments for all voice record/playback control and signal functions. Electrical compatibility is maintained across all interfaces: pushbutton control, SPI communication, microphone input, and speaker output.

Q: What is the difference between 28-TSSOP and 28-SOIC packaging?

A: Both are surface-mount packages with 28 pins. The 28-TSSOP package has a width of 11.80mm, while the 28-SOIC package has a width of 7.50mm. The SOIC package is narrower and requires different PCB land patterns and assembly considerations.

Q: Why is the ISD1760EY classified as obsolete?

A: The ISD1760EY has reached end-of-life status. Nuvoton Technology Corporation recommends the ISD1760SY as the active replacement for new designs and ongoing production support.

Q: Are there any compliance differences between the two parts?

A: Both components share identical REACH and ECCN classifications. The ISD1760SY is ROHS3 compliant, providing enhanced environmental compliance. Both maintain MSL 3 moisture sensitivity ratings.

Q: What are the key electrical parameters that must match for substitution?

A: Supply voltage (2.4 V–5.5 V), operating temperature range (0°C–70°C), sampling frequency (4–12 kHz), recording duration (40–120 seconds), and interface types (Pushbutton, SPI) must remain identical. Both the ISD1760EY and ISD1760SY meet these requirements.
