Overview
The ISD5108SYIR is a single-chip voice record and playback IC from the Nuvoton ISD5100 ChipCorder series. It provides 4 to 8 minutes of recording duration depending on the sampling rate, which ranges from 4 kHz to 8 kHz. The device features an I2C serial interface for control and digital data transfer, supporting both analog and digital storage within its 2 Mb memory array. It operates on a supply voltage of 2.7 V to 3.6 V and includes integrated automatic gain control, volume control, and a speaker driver. The component is housed in a 28-lead SOIC package.
Feature Summary
- Integrated single-chip solution combining voice recording, playback, and digital data storage capabilities.
- Supports dual storage of analog audio messages and digital system parameters via a unified memory array.
- Features an I2C serial interface requiring only two control lines for comprehensive device management.
- Includes built-in automatic gain control, volume adjustment, and power amplifier for direct speaker interfacing.
Applications
- Cellular phone answering machines and voice memo functions
- Automotive communication systems and GPS navigation units
- Portable consumer electronics requiring low-power voice messaging
Procurement Notes
Verify the specific suffix 'R' indicates tape and reel packaging when sourcing this part number. Confirm the manufacturing status as the ISD5100 series has undergone end-of-life notifications. Ensure compatibility with the required I2C bus speed and logic voltage levels for the target application design.
Selection Notes
Select the ISD5108SYIR when a recording duration between 4 and 8 minutes is required. Choose this model over the ISD5104 or ISD5116 based on specific memory capacity needs. Ensure the application supports the 2.7 V to 3.6 V operating range and utilizes the 28-SOIC package form factor.
Part Context
This component belongs to the ISD5100 ChipCorder series, which enhances the previous ISD5000 architecture by adding I2C control and digital data storage. The series includes variants with different durations, such as the ISD5102, ISD5104, and ISD5116, all sharing similar functional blocks but differing in memory size and recording time.
Replacement Considerations
Publicly confirmed substitutes include the I3800FYI and I3900FYI models recommended by the manufacturer. Verify pinout and register compatibility before replacing the discontinued ISD5108SYIR with these alternative part numbers.
