ISD17150PY

Overview

The ISD17150PY is a single-chip voice record and playback IC from the ChipCorder series by Nuvoton Technology Corporation. It supports multiple message recording with a duration range of 33 to 100 seconds. The device features an internal oscillator and accepts analog single-ended microphone input. It outputs analog single-ended signals via PWM for speaker drive. Operating on a supply voltage of 2.4 V to 5.5 V, it supports sampling frequencies between 4 kHz and 12 kHz. The component utilizes SPI and button interfaces for control and is housed in a 28-SOIC package.

Feature Summary

• Integrated automatic gain control and volume adjustment capabilities
• Supports multi-message recording and playback functionality
• Includes built-in internal oscillator for simplified circuit design

Applications

• Voice messaging systems
• Automotive warning devices
• Industrial equipment alarms

Procurement Notes

Verify current availability as the ISD17150SYI variant is marked obsolete. Confirm pin compatibility and functional equivalence with recommended manufacturer substitutes such as I2361YYI or I3800FYI before procurement. Ensure sourcing channels provide genuine components to avoid counterfeit risks associated with end-of-life parts.

Selection Notes

Select this component for applications requiring simple voice prompts without external microcontrollers. Verify that the required recording time falls within the 33 to 100-second range. Ensure the system power supply aligns with the 2.4 V to 5.5 V operating window. Consider the 28-SOIC package dimensions for PCB layout constraints.

Part Context

This part belongs to the ISD1700 series of voice record/playback ICs. These devices are designed for low-cost, high-reliability voice applications. The series typically integrates flash memory, audio codecs, and control logic on a single die, eliminating the need for complex digital signal processing hardware.

Replacement Considerations

Manufacturer recommends I2361YYI, I3800FYI, and I3900FYI as potential replacements. Verify electrical specifications and pinout compatibility for these alternatives.
