ISD1916SYI01

Overview

The ISD1916SYI01 is a single-chip multiple-message record/playback device from the ISD1900 ChipCorder series. It supports dual operating modes: Address Mode and Direct Mode, allowing flexible message configuration via hardware pins. The device operates on a supply voltage ranging from 2.4V to 5.5V. Sampling frequency selection is achieved through an external resistor (Rosc), with options spanning 4 kHz to 12 kHz, which directly determines the recording duration. For the ISD1916 derivative, durations range from 10.6 seconds at 12 kHz to 32 seconds at 4 kHz. It features differential microphone inputs with Automatic Gain Control (AGC) and a Class-D PWM speaker driver capable of directly driving an 8Ω load.

Feature Summary

• Dual operational modes including Address Mode for variable duration messages and Direct Mode for fixed-duration random access.

Applications

• Standalone voice recording and playback systems
• Voice input devices such as remote controls and smart switches
• Industrial automation audio interfaces

Procurement Notes

Verify the specific suffix SYI01 against official Nuvoton documentation to confirm package type and temperature grade. Ensure ordering details match the exact derivative requirements for your application design.

Selection Notes

Select this component when standalone audio messaging without a microcontroller is required. Consider the ISD1916 memory size if shorter message durations are sufficient. Evaluate the need for Address or Direct mode based on message flexibility requirements.

Part Context

The ISD1916SYI01 belongs to the ISD1900 series, which includes derivatives like ISD1932 and ISD1964 offering larger memory capacities. These devices share the same core architecture and pinout compatibility, differing primarily in storage size and resulting message durations.

Replacement Considerations

ISD1932SYI01 and ISD1964SYI01 offer increased memory capacity while maintaining pin compatibility. Verify functional equivalence before substitution.
