ISD5116P

Overview

The ISD5116P is a single-chip voice record/playback device from the ChipCorder series, manufactured by Nuvoton Technology Corporation. It supports message durations ranging from 8 minutes 44 seconds to 17 minutes 28 seconds, depending on the sampling rate. The device operates with a supply voltage of 2.7 V to 3.3 V and features an I2C serial interface for control. Sampling frequencies are configurable at 4 kHz, 5.3 kHz, 6.4 kHz, or 8 kHz. The filter passband ranges from 1.7 kHz to 3.4 kHz. It is housed in a 28-pin TSOP package.

Feature Summary

• Fully integrated single-chip solution with dual storage capability for both digital and analog information.
• Low power consumption with standby current as low as 1 µA and support for 2.0V and 3.0V interface logic.
• Enhanced voice features including one or two-way conversation recording, private call screening, and personalized outgoing messages.
• Standard and Fast mode I2C serial interface allowing fully addressable multiple message handling.

Applications

• Cellular phones and portable communication devices
• Automotive communications and GPS/navigation systems
• In-terminal answering machines and voice memo recorders

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'P' corresponds to the Plastic Small Outline Integrated Circuit (SOIC) or PDIP package variant as defined in the ordering information section of the datasheet. Ensure compatibility with the required operating temperature range for the specific application environment before finalizing procurement.

Selection Notes

Select this component when a fully integrated voice recording solution with digital data storage is required. Consider the ISD5116P if the design necessitates an I2C interface to minimize pin count and allows for software-configurable sampling rates. Evaluate the trade-off between message duration and audio quality based on the chosen sample rate within the 4 kHz to 8 kHz range.

Part Context

The ISD5116P belongs to the Winbond/Nuvoton ISD5100 series of ChipCorder products. This series utilizes patented multilevel storage technology to store voice signals directly into solid-state nonvolatile memory without compression. The 'P' suffix typically denotes the SOIC or PDIP package option, distinct from the TSOP or die variants available in the broader ISD5116 family.
