Overview
The ISD15116FYI is a multi-message ChipCorder featuring digital compression, comprehensive memory management, flash storage, and integrated analog/digital audio signal paths. It supports message recording with address-free allocation and pre-recorded voice prompts using high-quality compression. The device utilizes flash memory for non-volatile audio record/playback with durations up to 8 minutes. It accepts digital audio data via I2S or SPI interfaces and includes built-in analog audio inputs, line drivers, and speaker drivers. Operating voltage ranges from 2.7V to 3.6V, with an industrial temperature range of -40°C to 85°C.
Feature Summary
- Supports fast digital programming with rates up to 1Mbits/second.
- Enables address-free recording where the device allocates memory and returns start addresses via SPI.
- Offers multiple compression algorithms including ADPCM, µ-Law, Differential µ-Law, and PCM.
- Integrates Class D PWM speaker driver and configurable analog outputs.
Applications
- Voice prompting systems
- Industrial control panels
- Smart home devices
Procurement Notes
Verify the specific suffix FYI against the manufacturer's official ordering information to confirm package type, temperature grade, and any unique manufacturing lot requirements. Ensure compatibility with the required operating voltage and interface protocols before procurement.
Selection Notes
Select this component for applications requiring non-volatile voice storage with flexible compression options. Consider the available sampling frequencies and the need for I2S or SPI digital input versus analog inputs when designing the system architecture.
Part Context
This part belongs to the ISD15100 series of ChipCorder devices. The series is characterized by its ability to handle multi-message recordings and pre-programmed macros. It integrates both analog and digital audio paths within a single chip solution.
Replacement Considerations
Check for other variants within the ISD15100 series that may offer different pin counts or memory sizes. Verify if alternative packages like LQFP are available for the same functional specifications.
FAQ
