ISD5116SYIR

Overview

The ISD5116SYIR is a single-chip voice record and playback device from Nuvoton Technology Corporation, part of the ChipCorder series. It supports message durations ranging from 8 minutes 44 seconds to 17 minutes 28 seconds, depending on the sampling rate. The device operates with a supply voltage between 2.7 V and 3.3 V and features an I2C serial interface for control. It utilizes internal or external oscillators and is housed in a 28-TSOP package. The filter passband ranges from 1.7 kHz to 3.4 kHz, and it supports sampling frequencies from 4 kHz to 8 kHz.

Feature Summary

• Integrates digital storage capability alongside analog voice recording within a single chip solution.
• Features fully integrated audio paths including automatic gain control, volume control, and speaker driver.
• Supports low power consumption with standby current as low as 1 µA and individual stage power-down capabilities.
• Provides flexible interface options supporting both 2.0V and 3.0V logic levels for portable applications.

Applications

• Cellular phone messaging and voice memo functions
• Automotive communication systems
• GPS and navigation system prompts
• Portable electronic devices requiring voice storage

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix SYIR corresponds to the required tape and reel packaging format. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans to ensure long-term supply availability.

Selection Notes

Select this model when dual analog and digital data storage is required within a single IC. Ensure the application environment stays within the specified operating temperature range. Verify that the host microcontroller supports the standard I2C protocol for seamless integration and control of the recording and playback functions.

Part Context

This component belongs to the ISD5116 series, which enhances the earlier ISD5000 architecture by adding I2C interface capabilities. It is designed for high-quality voice and music reproduction using multi-level storage technology. The series is intended for applications needing significant recording duration with minimal external circuitry.

Replacement Considerations

Publicly confirmed substitute part numbers include MFR Recommended I2361YYI, I3800FYI, and I3900FYI from Nuvoton Technology Corporation. Verify pin compatibility and electrical specifications before substituting these alternatives into existing designs.
