ISD5116PY

Overview

The ISD5116PY 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 selected sampling frequency of 4 kHz to 8 kHz. The device features an I2C serial interface for control and data transfer, operating within a supply voltage range of 2.7 V to 3.3 V. It integrates analog audio processing, including automatic gain control and speaker drivers, alongside digital storage capabilities. The component is housed in a 28-pin TSOP package.

Feature Summary

• Fully integrated single-chip solution combining voice record/playback with digital data storage
• I2C serial interface for address, control, and duration selection minimizing pin count
• Dual storage capability for both analog voice messages and digital system parameters
• Integrated audio path components including AGC, volume control, and speaker driver

Applications

• Cellular phone messaging and call screening
• Automotive communication systems
• GPS and navigation systems
• Portable electronic devices requiring voice memo functionality

Procurement Notes

Verify the specific suffix 'PY' against official manufacturer documentation to confirm exact temperature grade and packaging specifications. Cross-reference the part number with current availability status as legacy components may have end-of-life designations. Ensure compatibility with existing I2C bus configurations and voltage levels during integration planning.

Selection Notes

Select this component when a compact, low-power voice messaging solution with digital memory support is required. Consider the trade-off between recording duration and audio bandwidth based on the chosen sampling rate. Verify that the host microcontroller can support the necessary I2C protocol and address configuration for multiple device instances if needed.

Part Context

The ISD5116 belongs to the Winbond/Nuvoton ChipCorder family, which utilizes patented multilevel storage technology for nonvolatile voice data retention. This architecture allows direct storage of uncompressed audio signals, eliminating the need for external compression algorithms or dedicated DSPs for basic voice functions.

Replacement Considerations

Check for updated revisions within the ISD5100 series or equivalent Nuvoton voice ICs. Verify pinout compatibility and I2C register mapping before substituting. Confirm that alternative parts support the same dual analog/digital storage requirements and package dimensions.
