ISD5216SYI Voice Record/Playback IC Equivalent & Substitute Parts

Part Overview

The ISD5216SYI is a ChipCorder® voice record/playback interface IC manufactured by Nuvoton Technology Corporation, designed for multiple message applications with recording and playback durations of 8 minutes 3 seconds to 16 minutes 6 seconds. The device features I2C interface control, analog single-ended and I2S signal processing, and integrated automatic gain control with volume management.

The ISD5216SYI is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued design support, maintain supply chain reliability, and enable component sourcing for legacy system maintenance and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISD5216SYI is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Nuvoton Technology Corporation
• Series: ChipCorder®
• Interface Protocol: I2C
• Package / Case: 28-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 2.7 V ~ 3.3 V
• Operating Temperature: -40°C ~ 85°C (TA)
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Compatible Signal Processing Parameters:

• Input Signal Types: Analog - Single Ended, Microphone (core requirement)
• Output Signal Types: Analog - Single Ended, PWM Speaker Output (core requirement)
• Sampling Frequency: 4 ~ 8kHz

The ISD5116SYI qualifies as a substitute part because it maintains all mandatory matching parameters and supports the required signal processing capabilities. While recording/playback duration differs (8 min 44 sec ~ 17 min 28 sec versus 8 min 3 sec ~ 16 min 6 sec), this represents an extended capability rather than a limitation, making it functionally compatible for applications requiring voice record/playback functionality within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The ISD5116SYI is the qualified substitute for the obsolete ISD5216SYI based on the following engineering criteria:

Product Status Alignment: The ISD5116SYI maintains active product status with Nuvoton Technology Corporation, ensuring ongoing manufacturer support, documentation availability, and supply chain continuity compared to the obsolete ISD5216SYI.

Compliance and Certification: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory compliance equivalence. The ISD5116SYI achieves RoHS3 compliance, providing enhanced environmental and material restriction adherence.

Electrical and Mechanical Compatibility: The ISD5116SYI maintains identical supply voltage range (2.7 V ~ 3.3 V), operating temperature range (-40°C ~ 85°C), and package configuration (28-SOIC). I2C interface protocol, sampling frequency (4 ~ 8kHz), and moisture sensitivity level (MSL 3) are preserved.

Signal Processing Capability: The ISD5116SYI supports all required input and output signal types for the ISD5216SYI application domain. Extended recording/playback duration (8 min 44 sec ~ 17 min 28 sec) provides additional functional capacity without reducing compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ISD5116SYI directly replace the ISD5216SYI in existing PCB designs?

A: Yes. Both parts share identical 28-SOIC package dimensions (0.295", 7.50mm Width), pinout compatibility through I2C interface protocol, and equivalent electrical specifications (2.7 V ~ 3.3 V supply, -40°C ~ 85°C operating range). No PCB layout modifications are required.

Q: What are the key differences between ISD5216SYI and ISD5116SYI?
