ISD5116EY

Overview

The ISD5116 is a single-chip voice record and playback device featuring digital storage capability, supporting up to 16 minutes of duration. It utilizes an I2C serial interface for address, control, and duration selection, requiring only two control lines. The device supports logic interfaces of 2.0V and 3.0V, with supply voltages ranging from +2.7V to +3.3V. Typical operating currents are 15 mA during playback, 30 mA during recording, and 12 mA in feedthrough mode, while standby current is typically 1 µA. It offers up to 4 MB of available memory for storing phone numbers or system parameters alongside analog audio.

Feature Summary

• Fully integrated single-chip solution combining voice record/playback with digital data storage capabilities.
• Supports dual storage of digital and analog information within the same memory array.
• Features low power consumption with individually powered-down stages and ultra-low standby current.
• Includes enhanced voice features such as one/two-way conversation recording, private call screening, and personalized outgoing messages.

Applications

• Cellular phones and portable communication devices
• Automotive communications and car kit interfaces
• GPS and navigation systems
• In-terminal answering machines

Procurement Notes

Verify the specific package type (TSOP, SOIC, PDIP) and temperature grade (Commercial, Extended, Industrial) required for your application. Confirm that the I2C slave address configuration via A0 and A1 pins matches your system design. Ensure voltage levels align with the supported 2.0V or 3.0V logic interface options before procurement.

Selection Notes

Select the ISD5116 when both analog voice messaging and digital data storage are needed on a single chip. Consider the sampling rate requirements (4.0 kHz to 8.0 kHz) to balance between audio quality and total recording duration. Verify that the host microcontroller supports the standard and fast mode I2C protocol for proper communication.

Part Context

The ISD5116 is part of Nuvoton's (formerly Winbond) ChipCorder family, enhancing the ISD5000 architecture. It integrates sampling clocks, anti-aliasing filters, smoothing filters, and multi-level storage arrays on a single die. This technology allows for uncompressed voice storage, providing superior audio reproduction compared to compressed alternatives.

Replacement Considerations

Check for compatible successors in the ISD51xx series or newer ChipCorder generations. Verify pin compatibility if replacing in existing designs, particularly regarding the I2C interface and analog input/output configurations.

FAQ

How is the memory divided between analog and digital storage?

The memory array can be allocated to either digital or analog storage by the system microcontroller using op codes during recording. A Message Address Table (MAT) tracks which pages contain analog or digital data.

What is the typical message retention period without power?

The on-chip nonvolatile memory retains messages for up to 100 years typically without power.

Can the device handle full-duplex conversation recording?

Yes, the ISD5116 supports one-way (simplex) and two-way (duplex) conversation recording, allowing for features like call screening and answering machine functions.
