Overview
The ISD17180SYR is a voice recording and playback integrated circuit from Nuvoton Technology Corporation, belonging to the ChipCorder series. It supports multiple messages with a total duration of 120 to 360 seconds. The device features an internal oscillator and operates on a supply voltage ranging from 2.4 V to 5.5 V. It accepts analog single-ended input signals from a microphone and provides analog single-ended or PWM speaker output. Sampling frequencies are configurable between 4 kHz and 12 kHz. The component is housed in a 28-SOIC package (0.295 inch, 7.50 mm width) and is designed for surface mount installation. It supports button and SPI interfaces.
Feature Summary
- Integrated voice recording and playback functionality with support for multiple message segments.
- Built-in automatic gain control and volume control capabilities for audio signal management.
- Internal oscillator eliminates the need for external clock components.
- Supports both direct button interface and serial peripheral interface (SPI) for system integration.
Applications
- Voice messaging systems
- Automated announcements
- Interactive voice response units
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the received parts match the specified 28-SOIC package and part number exactly. Check for physical damage to pins and ensure proper handling procedures are followed during storage and assembly. Review the latest datasheet for any updates regarding pin configurations or electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a dedicated voice recording solution with up to 360 seconds of total capacity is required. Consider the 2.4 V to 5.5 V operating range for compatibility with various power supplies. Evaluate the need for SPI versus button interfaces based on system complexity. Ensure the 28-SOIC package fits the available PCB space and thermal requirements.
Part Context
The ISD17180SYR is part of the ISD1700 series by Nuvoton Technology Corporation, which specializes in voice recording and playback ICs. This series utilizes proprietary technology to store voice data directly on-chip without requiring external memory. The ChipCorder family offers various durations and interface options to suit different application needs, providing a compact and cost-effective solution for voice-enabled products.
Replacement Considerations
Public confirmed substitute part numbers include I2361YYI and I3800FYI from Nuvoton Technology Corporation. Verify pinout compatibility and functional equivalence before substitution. Note that the original ISD1750SYI01 is obsolete; however, the ISD17180SYR is a distinct model within the same product line with different recording capacities.
