TAS3208PZPR Equivalent & Substitute Parts

Part Overview

The TAS3208PZPR is a fixed-point embedded audio processor manufactured by Texas Instruments, designed for audio signal processing applications. It integrates a 135MHz clock rate with 30.3kB on-chip RAM and supports multiple audio interfaces including AAI/O, DAI/O, I2C, and I2S. The device operates at 3.30V for both I/O and core voltage levels.

The TAS3208PZPR has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems currently utilizing this component.

Substitute Part Grouping Explanation

The substitute parts identified for the TAS3208PZPR are the TLV320AIC3256IRSBR and TLV320AIC3256IRSBT. These substitutes are qualified based on the following criteria:

Interface Compatibility: Both substitute parts support I2C and Serial interfaces, which align with the primary control interfaces of the original part.

Audio Processing Capability: The TLV320AIC3256 series provides stereo audio codec functionality with 32-bit resolution, 2 ADCs, and 2 DACs, supporting audio signal processing requirements.

Manufacturer Consistency: Both substitutes are manufactured by Texas Instruments, maintaining design ecosystem continuity.

Compliance Alignment: All parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency.

Product Status: The substitute parts carry Active product status, ensuring long-term availability and supply chain support.

The key parameters determining substitution eligibility are: manufacturer, audio interface support, I2C/Serial communication capability, surface mount packaging, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TAS3208PZPR is obsolete, while both TLV320AIC3256IRSBR and TLV320AIC3256IRSBT maintain Active product status. Active status ensures continued manufacturing support, technical documentation availability, and supply chain reliability.

Compliance Certification: All three parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component deployment.

Packaging Transition: The substitute parts utilize 40-WFQFN packaging compared to the original 100-TQFP package. PCB layout redesign is required to accommodate the different package footprint and pin configuration.

Moisture Sensitivity: The substitute parts feature MSL 2 (1 Year) compared to the original MSL 3 (168 Hours), providing improved moisture tolerance during storage and handling.

Operating Temperature Range: The substitute parts support -40°C ~ 85°C, extending the lower temperature limit compared to the original -20°C ~ 70°C range.

Packaging Option: TLV320AIC3256IRSBT is supplied in Tape & Reel (TR) packaging, while TLV320AIC3256IRSBR is supplied without specified tape and reel packaging. Selection depends on production volume and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLV320AIC3256 series directly replace the TAS3208PZPR without design modifications?

A: No. While both parts are Texas Instruments audio processing components with I2C interface support, the package transition from 100-TQFP to 40-WFQFN requires PCB layout redesign, including footprint changes and potential signal routing modifications.

Q: What are the key interface differences between the original and substitute parts?

A: The TAS3208PZPR supports AAI/O, DAI/O, I2C, and I2S interfaces. The TLV320AIC3256 series supports I2C, Serial, and SPI™ interfaces. I2C compatibility is maintained, but AAI/O and DAI/O interface requirements must be evaluated against the Serial and SPI™ capabilities of the substitute.

Q: Are there voltage supply differences that affect circuit design?

A: Yes. The TAS3208PZPR operates at 3.30V for both I/O and core voltage. The TLV320AIC3256 series requires 1.5V ~ 1.95V for analog supply and 1.26V ~ 1.95V for digital supply. Power supply circuit redesign is necessary.

Q: Which substitute part should be selected for high-volume production?

A: TLV320AIC3256IRSBT is supplied in Tape & Reel (TR) packaging with 3200 Pcs inventory, making it suitable for automated assembly processes and high-volume production runs.

Q: Do the substitute parts maintain the same regulatory compliance?

A: Yes. Both TLV320AIC3256IRSBR and TLV320AIC3256IRSBT maintain ROHS3 compliance and REACH unaffected status, consistent with the original TAS3208PZPR.

Q: What is the impact of the extended operating temperature range on system design?

A: The substitute parts support -40°C ~ 85°C compared to the original -20°C ~ 70°C. This extended range provides greater thermal margin for applications operating in extreme environments, but does not require design modifications if the original temperature range was sufficient.
