Overview
The ISD15102FYI is a multi-message ChipCorder featuring digital compression, comprehensive memory management, flash storage, and integrated analog/digital audio signal paths. It supports address-free recording and playback via SPI or I2S interfaces. The device operates on a 2.7V to 3.6V supply with industrial temperature range (-40°C to 85°C). Audio durations reach up to 8 minutes using 8kHz/4bit ADPCM. It includes Class-D PWM speaker drivers delivering 350mW at 3.3V into an 8Ω load. The component is housed in a 48-lead LQFP package.
Feature Summary
- Supports fast digital programming with rates up to 1Mbits/second.
- Features address-free message management for simplified code development.
- Integrates multiple compression algorithms including ADPCM, µ-Law, and PCM.
- Provides flexible audio input/output options with analog line drivers and speaker outputs.
Applications
- Voice record and playback devices
- Automated voice prompts systems
- Industrial control panels with audio feedback
Procurement Notes
Verify the specific suffix 'FYI' against the manufacturer's current ordering information to confirm package type and temperature grade. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm that the 48-lead LQFP footprint matches the PCB design constraints. Check for any recent revision updates in the datasheet that may affect pin definitions or electrical characteristics.
Selection Notes
Select this component when non-volatile audio storage with address-free management is required. It is suitable for applications needing high sampling frequencies and I2S digital audio interfaces. Consider the built-in analog inputs and Class-D output if external amplifiers are to be avoided. Verify that the available compression formats meet the desired audio quality and duration requirements.
Part Context
The ISD15102FYI belongs to the ISD15100 series of ChipCorder devices from Nuvoton Technology Corporation. This series is designed for single-chip voice recording and playback solutions. It distinguishes itself by offering I2S digital audio interfaces and faster digital recording capabilities compared to earlier generations. The family utilizes flash memory to provide robust, non-volatile audio storage.
Replacement Considerations
The ISD-DEMO15100 demonstration board supports the ISD15100, ISD15C00, and ISD3900 series. While these share functional similarities, direct pin-to-pin replacement requires verification of electrical parameters and interface compatibility. Consult the respective datasheets for ISD15C00 and ISD3900 to ensure suitability as substitutes.
