ISD5108SYR

Overview

The ISD5108SYR is a single-chip voice record and playback solution from the Nuvoton ISD5100 ChipCorder series, housed in a 28-lead SOIC package. It provides 4 to 8 minutes of recording duration depending on the selected sampling rate. The device integrates analog audio processing, including microphone amplifiers, automatic gain control (AGC), and a speaker driver, alongside digital memory capabilities. It operates on a supply voltage ranging from 2.7V to 3.3V for commercial temperatures and up to 3.6V for industrial temperatures. Control is managed via a standard I2C serial interface requiring only two lines.

Feature Summary

• Integrates dual storage capability for both analog voice messages and digital data within a single chip.
• Features fully integrated analog audio paths with programmable interfaces, eliminating external circuitry requirements.
• Supports flexible message management through addressable memory pages and interrupt feedback pins.

Applications

• Cellular phone answering machines and voice memo functions
• Automotive communication systems and GPS navigation units
• Portable consumer electronics requiring low-power voice messaging

Procurement Notes

Verify that the ordering suffix 'R' corresponds to the reel packaging specification as defined in the manufacturer's official documentation. Confirm the specific temperature grade and logic voltage compatibility required for your system design before finalizing the purchase order.

Selection Notes

Select this model when a recording duration between 4 and 8 minutes is required. Ensure the host microcontroller supports the I2C protocol for command execution. Verify that the system power supply falls within the specified operating range for the intended environmental temperature conditions.

Part Context

This component belongs to the ISD5100 ChipCorder series, which enhances the previous ISD5000 architecture by adding I2C control and digital storage features. The series includes variants with different memory capacities, such as the ISD5102, ISD5104, and ISD5116, offering scalable recording times from 1 to 16 minutes.

Replacement Considerations

Compatible substitutes within the same family include the ISD5108SY and ISD5108EYI. These parts share identical functional specifications but may differ in package type or temperature rating. Verify pinout compatibility and electrical characteristics before substitution.
