ISD17150SYIR

Overview

The ISD17150SYIR is a voice recording and playback integrated circuit from Nuvoton Technology Corporation's ChipCorder series. It supports multiple message formats with a total recording duration ranging from 33 to 100 seconds. The device operates on a supply voltage of 2.4 V to 5.5 V and features an internal oscillator. It utilizes SPI or button interfaces for control and accepts analog single-ended microphone input. Audio output is provided via analog single-ended signals and PWM speaker output. The component is housed in a 28-SOIC package (0.295 inch, 7.50 mm width) and supports sampling frequencies between 4 kHz and 12 kHz. It includes automatic gain control and volume control features, operating within a temperature range of -40°C to 85°C.

Feature Summary

• Supports multiple message recording and playback modes with variable duration capabilities.
• Integrates automatic gain control and volume control for optimized audio performance.
• Offers flexible interface options including SPI communication and direct button controls.
• Features an internal oscillator eliminating the need for external clock components.

Applications

• Voice messaging systems
• Automated announcements
• Educational learning devices

Procurement Notes

Verify the specific suffix 'R' against official documentation to confirm tape-and-reel packaging status, as datasheets may list standard tube packaging. Confirm end-of-life status and availability of manufacturer-recommended substitutes such as I2361YYI or I3800FYI for current production needs.

Selection Notes

Select this component when a dedicated voice IC with up to 100 seconds of storage is required without external microcontrollers. Ensure the design accommodates the 28-SOIC footprint and 2.4 V to 5.5 V power supply range. Verify that the required sampling frequency falls within the 4 kHz to 12 kHz operational window for the desired audio quality.

Part Context

The ISD17150SYIR belongs to the ISD1700 series, which focuses on low-cost, high-quality voice recording solutions. This series is designed for applications requiring simple integration of voice functionality into consumer electronics and industrial controls without complex digital signal processing overhead.

Replacement Considerations

Manufacturer recommended substitutes include I2361YYI and I3800FYI. Verify pin compatibility and functional equivalence before replacement due to potential differences in package or feature sets.
