TAS3202PAGR Equivalent & Substitute Parts

Part Overview

The TAS3202PAGR is a fixed-point audio digital signal processor (DSP) manufactured by Texas Instruments, designed for embedded audio processing applications. It features a 135MHz clock rate, 31.625kB on-chip RAM, and supports multiple serial interfaces including I2C, I2S, PCM, SPI, and UART. The device is packaged in a 64-TQFP surface mount configuration and operates at 3.30V for both I/O and core voltage levels.

The TAS3202PAGR is designated as Last Time Buy, indicating that Texas Instruments has discontinued or will discontinue production. This status necessitates identification of equivalent and substitute components to maintain design continuity and support long-term product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAS3202PAGR is determined by the following critical parameters:

Primary Substitution Criteria:

• Functional classification (audio DSP or audio codec interface)
• Interface compatibility (I2C, I2S, PCM, SPI, UART support)
• Operating voltage range (3.30V I/O and core voltage)
• Package type and pin count (64-TQFP surface mount)
• On-chip memory capacity (31.625kB RAM minimum)
• Clock rate capability (135MHz minimum)
• RoHS3 compliance and MSL rating

Identified Substitutes:

1. TAS3202PAG - Direct equivalent with identical electrical specifications and functionality. Differs only in packaging format (Tray vs. Tape & Reel). Same 64-TQFP package, identical interface set, clock rate, and memory configuration. Product Status: Active.

2. PCM3070IRHBR - Functional alternative for audio processing applications. Operates within compatible voltage ranges (1.8V ~ 3.6V supply), supports I2C and SPI interfaces, and provides stereo audio codec functionality. Packaged in 32-VQFN (5x5), representing a different form factor. Product Status: Active.

Parameter Comparison

Engineering Selection Recommendations

TAS3202PAG is the primary substitute for TAS3202PAGR. Both devices share identical electrical specifications, functional capabilities, and package configuration. The only difference is packaging format: TAS3202PAGR is supplied in Tape & Reel format, while TAS3202PAG is supplied in Tray format. Both maintain ROHS3 compliance and identical MSL ratings. TAS3202PAG is currently in Active product status, ensuring continued availability and support.

PCM3070IRHBR serves as a functional alternative for applications requiring stereo audio codec functionality with I2C and SPI interface support. This substitute is suitable when the specific DSP processing capabilities of the TAS3202 series are not required and a codec-based audio interface is acceptable. The PCM3070IRHBR operates across a wider voltage range (1.8V ~ 3.6V), supports an extended operating temperature range (-40°C ~ 85°C), and features improved MSL rating (3 vs. 4). However, the 32-VQFN package represents a significant form factor change from the 64-TQFP, requiring PCB layout redesign.

Frequently Asked Questions (FAQ)

Q: Can TAS3202PAG directly replace TAS3202PAGR without design changes?

A: Yes. TAS3202PAG is a direct electrical and functional equivalent. Both devices feature identical pin configurations, electrical specifications, interface protocols, and operating parameters. The only difference is packaging format (Tray vs. Tape & Reel), which does not affect circuit operation. No schematic or PCB modifications are required.

Q: What are the key differences between TAS3202PAGR and PCM3070IRHBR?

A: TAS3202PAGR is a fixed-point audio DSP with 31.625kB on-chip RAM and 135MHz clock rate, designed for programmable audio signal processing. PCM3070IRHBR is a stereo audio codec with integrated ADC/DAC functionality, optimized for audio interface applications. The TAS3202 supports five interface protocols (I2C, I2S, PCM, SPI, UART), while PCM3070 supports three (I2C, Serial, SPI). Package form factors differ significantly: 64-TQFP vs. 32-VQFN. PCM3070IRHBR is suitable only when codec-based audio processing replaces the DSP functionality.

Q: Is PCM3070IRHBR compatible with existing TAS3202PAGR designs?

A: PCM3070IRHBR is not a pin-compatible substitute. The different package type (32-VQFN vs. 64-TQFP), pin count, and functional architecture require complete PCB redesign and firmware modification. Use PCM3070IRHBR only when design flexibility permits architectural changes.

Q: What is the significance of Last Time Buy status for TAS3202PAGR?

A: Last Time Buy indicates Texas Instruments has ceased or will cease production of TAS3202PAGR. Existing inventory is limited. TAS3202PAG (Active status) is the recommended long-term replacement to ensure continued component availability for future production runs and design revisions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TAS3202PAGR, TAS3202PAG, and PCM3070IRHBR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: How do operating temperature ranges affect substitution decisions?

A: TAS3202PAGR and TAS3202PAG operate within 0°C ~ 70°C. PCM3070IRHBR extends this range to -40°C ~ 85°C. If the application requires operation below 0°C or above 70°C, PCM3070IRHBR provides broader temperature coverage. For standard industrial applications within 0°C ~ 70°C, both TAS3202 variants are suitable.
