ISD5116SYR

Overview

The ISD5116SYR 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 digital data storage, with up to 4 MB of available memory capacity. It operates on a supply voltage of 2.7 V to 3.3 V and includes integrated automatic gain control, volume control, and speaker driver capabilities.

Feature Summary

• Integrates analog and digital storage within a single nonvolatile memory array for flexible message management.
• Supports full-duplex conversation recording and simplex or duplex playback via configurable audio paths.
• Features built-in automatic gain control, power amplifier, and volume control to minimize external circuitry.

Applications

• Cellular phone voice messaging and answering machine functions
• Automotive communication systems and GPS navigation devices
• Portable consumer electronics requiring low-power voice storage

Procurement Notes

Verify component authenticity through authorized distributors as the ISD5116SYR may be discontinued. Confirm package type matches the 28-pin TSOP specification. Check for RoHS compliance status in current datasheets. Ensure I2C address pins are configured correctly for system integration. Validate operating temperature range requirements against commercial specifications.

Selection Notes

Select this component when dual analog and digital storage is required on a single chip. Consider the I2C interface complexity if multiple devices share the bus. Evaluate power consumption requirements against the typical standby current of 1 µA. Verify that the 28-pin TSOP package fits the PCB layout constraints. Assess sampling rate needs against desired audio bandwidth and duration trade-offs.

Part Context

The ISD5116 belongs to the Winbond/Nuvoton ChipCorder family, utilizing patented multilevel storage technology. This architecture allows direct uncompressed voice storage in solid-state memory, eliminating the need for compression algorithms. The series is designed for portable applications where zero-power retention and high reliability are critical.

Replacement Considerations

Publicly confirmed substitute part numbers include MFR Recommended I2361YYI, I3800FYI, and I3900FYI from Nuvoton Technology Corporation. Verify pin compatibility and software register mapping before substitution. Check for any changes in operating voltage or interface timing parameters.
