ISD5116EYI

Overview

The ISD5116 is a single-chip voice record/playback device providing up to 16 minutes of duration with digital storage capability. It operates on a +2.7V to +3.3V supply voltage and supports 2.0V and 3.0V interface logic. The device features an I2C serial interface for control and data transfer, supporting Standard (100 kHz) and Fast (400 kHz) modes. Memory capacity reaches up to 4 MB, organized into 2048 pages of 2048 bits. Sampling frequencies are configurable at 4.0, 5.3, 6.4, or 8.0 kHz, affecting duration and bandwidth. Typical operating currents are 15 mA during playback, 30 mA during recording, and 1 µA in standby.

Feature Summary

• Fully integrated single-chip solution combining analog audio processing and nonvolatile digital storage without external components.
• Dual storage architecture allowing simultaneous allocation of memory space for both analog voice messages and digital system data.
• Integrated automatic gain control, power amplifier, speaker driver, and volume control to minimize external circuitry requirements.
• I2C serial interface enables low pin-count control with programmable sampling rates and fully addressable message management.

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 variant required, as the ISD5116 is available in TSOP, SOIC, PDIP, and die form. Confirm temperature grade availability, including Commercial, Extended, and Industrial options. Ensure the host microcontroller supports the I2C protocol for proper command execution and data handling during integration.

Selection Notes

Select the ISD5116 when a compact, low-power voice messaging solution with digital data storage is needed. Choose based on required recording duration versus sampling rate trade-offs. Verify that the application environment matches the supported voltage range and logic levels. Consider the available package types relative to board space constraints and thermal requirements.

Part Context

The ISD5116 belongs to the Winbond ChipCorder family, enhancing the ISD5000 architecture by adding I2C control and digital storage capabilities. It utilizes patented multilevel storage technology to retain voice and data in uncompressed form. This series targets portable electronics requiring high-quality audio reproduction with minimal component count and zero-power retention.
