ISD5116SIR

Overview

The ISD5116SIR is a single-chip voice record and playback device from the ChipCorder series, manufactured by Nuvoton Technology Corporation. It supports recording durations ranging from 8 minutes 44 seconds to 17 minutes 28 seconds, depending on the sampling frequency settings of 4 kHz, 5.3 kHz, 6.4 kHz, or 8 kHz. The device operates on a supply voltage between 2.7 V and 3.3 V and features an I2C serial interface for control and digital data storage. It utilizes nonvolatile multilevel storage technology to retain messages without power. The component is housed in a 28-pin TSOP package.

Feature Summary

• Integrates analog audio processing with digital memory capabilities on a single chip
• Supports simplex and duplex conversation recording and playback modes
• Includes automatic gain control, volume control, and speaker driver outputs
• Allows simultaneous storage of analog voice and digital system data

Applications

• Cellular phone messaging systems
• Automotive communication devices
• GPS and navigation systems
• Portable answering machines

Procurement Notes

Verify the specific suffix 'SIR' against official manufacturer documentation to confirm temperature range and package variations. Confirm current manufacturing status as legacy components may have limited availability. Ensure compatibility with existing I2C bus configurations and voltage levels during integration.

Selection Notes

Select this component when a fully integrated solution for voice messaging is required without external compression algorithms. Consider the trade-off between recording duration and audio bandwidth based on the chosen sampling rate. Verify that the host microcontroller can support the standard I2C protocol for command execution and address management.

Part Context

The ISD5116 belongs to the Winbond/Nuvoton ChipCorder family, which employs patented multilevel storage arrays. This architecture allows direct storage of uncompressed audio signals into solid-state memory, eliminating the need for complex codec hardware. The series is designed to minimize pin counts while providing high-quality audio reproduction and flexible message management.

Replacement Considerations

Check for updated revisions within the ISD5100 series. Verify pinout compatibility if substituting with other variants in the same package type. Confirm that alternative devices support the same I2C command set and voltage requirements.
