ISD5102EY

Overview

The ISD5102EY is a single-chip voice record/playback device from the ISD5100 ChipCorder series by Nuvoton Technology Corporation. It provides 1 to 2 minutes of recording duration using multilevel storage technology. The device supports dual storage of digital and analog data, with up to 512Kb of total memory capacity. It operates on a +2.7V to +3.3V supply voltage and features an I2C serial interface for control. Key electrical parameters include a typical standby current of 1µA, playback current of 15mA, and recording current of 30mA. It supports sampling frequencies of 4.0, 5.3, 6.4, or 8.0 kHz.

Feature Summary

• Integrated single-chip solution combining voice record, playback, and digital data storage capabilities without external components.
• Supports flexible audio path configuration for full-duplex conversation recording, voice memos, and answering machine functions.
• Utilizes patented multilevel flash memory for zero-power message retention and direct uncompressed signal storage.

Applications

• Cellular phone integrated answering machines and caller ID systems
• Automotive communication and navigation system alerts
• Portable GPS devices and handheld messaging units

Procurement Notes

Verify the specific ordering suffix 'EY' against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with the required I2C logic levels (2.0V or 3.0V) for the target system design. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the intended application requirements.

Selection Notes

Select this model when a recording duration between 1 and 2 minutes is sufficient for the application. Consider the ISD5100 series if digital data storage alongside voice is required. Evaluate the available sampling rates to balance audio quality against the desired message length. Verify that the I2C interface constraints align with the host microcontroller's capabilities.

Part Context

The ISD5102EY belongs to the ISD5100 ChipCorder series, which enhances the previous ISD5000 architecture. This series integrates sampling clocks, filters, and amplifiers into a single chip. It is designed to minimize pin count through I2C control while offering high-quality voice reproduction and robust digital storage features for portable electronic devices.

Replacement Considerations

ISD5102XYI: Alternative variant within the same series with potentially different packaging or temperature specifications. Verify pinout and electrical parameters before substitution.
