ISD5102X

Overview

The ISD5102X is a single-chip voice record and playback solution from the ISD5100 ChipCorder series, designed for messaging applications in portable products. It provides 1 to 2 minutes of recording duration using Nuvoton's patented multilevel storage technology, which stores voice signals directly into solid-state memory without compression. The device supports dual storage of digital and analog data, allowing flexible allocation of memory space. It operates on a supply voltage of +2.7V to +3.3V and features a standard I2C serial interface for control. Key electrical parameters include a typical standby current of 1µA, a typical playback current of 15mA, and a typical recording current of 30mA.

Feature Summary

• Fully integrated single-chip solution with built-in microphone amplifier, automatic gain control, power amplifier, and speaker driver.
• Supports simultaneous storage of digital data (e.g., phone numbers) and analog voice messages within the same memory array.
• Enables full-duplex conversation recording and simplex/duplex playback via configurable audio paths.
• Features low-power operation with individually controllable internal circuit blocks to minimize energy consumption.

Applications

• Cellular phones and mobile communication devices
• Automotive communications systems
• GPS and navigation systems
• In-terminal answering machines

Procurement Notes

Verify the specific suffix 'X' against the official ordering information table to confirm package type and temperature grade. Ensure the selected variant matches the required operating environment and physical footprint constraints for the target design.

Selection Notes

Select the ISD5102X when 1 to 2 minutes of recording time is sufficient. Consider the ISD5104 or higher variants if longer durations are needed. Verify that the host system supports the I2C protocol and can handle the 2.0V or 3.0V logic levels required by the interface.

Part Context

The ISD5102X belongs to the ISD5100 series, which enhances the previous ISD5000 architecture by adding I2C control and digital data storage capabilities. This series eliminates external components typically required for voice recording, such as compressors and amplifiers, by integrating them onto the chip.

Replacement Considerations

Direct replacements within the same family include the ISD5104, ISD5108, and ISD5116, which offer increased recording durations but may require different memory management strategies. Previous generation ISD5000 series parts are not pin-compatible due to the lack of I2C integration.
