ISD5116X

Overview

The ISD5116X is a member of the Nuvoton ISD5100 ChipCorder series, providing a fully integrated single-chip solution for voice record and playback applications. It supports recording durations from 8 to 16 minutes depending on the selected sampling frequency (4.0 kHz to 8.0 kHz). The device features up to 4 Mb of non-volatile storage capacity, allowing for dual storage of both analog audio data and digital information such as phone numbers or system parameters. It operates within a supply voltage range of +2.7V to +3.3V and supports 2.0V and 3.0V interface logic levels. Control is managed via a standard I2C serial interface requiring only two control lines.

Feature Summary

• Fully integrated single-chip architecture combining microphone inputs, automatic gain control, power amplifier, and speaker driver with zero-power flash memory storage.
• Dual storage capability enabling simultaneous retention of uncompressed analog voice messages and digital data within the same memory array.
• Configurable audio paths supporting simplex and duplex conversation recording, voice memos, and answering machine functions with user-controllable sampling rates.

Applications

• Cellular phones and portable communication devices
• Automotive communication systems
• GPS and navigation systems

Procurement Notes

Verify that the specific suffix 'X' corresponds to the required temperature grade and package type, as the datasheet lists DIE, SOP-28, and PDIP-28 options. Confirm the operating temperature range matches the application requirements, noting distinctions between commercial and industrial grades. Ensure the I2C address pins are configured correctly for the target system topology.

Selection Notes

Select the ISD5116X when an 8 to 16-minute recording duration is required at standard voice quality settings. Consider the available memory allocation between analog and digital storage based on application needs. Verify compatibility with the host microcontroller's I2C voltage levels and ensure sufficient supply current capabilities for peak playback and recording operations.

Part Context

The ISD5116X belongs to the ISD5100 series, which enhances the previous ISD5000 architecture by integrating an I2C interface and digital data storage capabilities. This series utilizes Nuvoton's patented multilevel storage technology to store voice signals directly into solid-state memory without compression, ensuring high-fidelity audio reproduction while minimizing external component count.

Replacement Considerations

ISD5108: Offers 4 to 8 minutes of recording time with 2 Mb storage. ISD5104: Provides 2 to 4 minutes of recording time with 1 Mb storage. ISD5102: Supports 1 to 2 minutes of recording time with 512 Kb storage. All variants share the same pinout and I2C control protocol.
