TUSB3200CPAH

Overview

The TUSB3200CPAH is a USB Streaming Controller (STC) designed for isochronous data streaming applications, such as digital speakers. It integrates an 8052 MCU core with 4KB ROM and 8KB RAM, supporting USB Specification 1.1 and Audio Class 1.0 at 12 Mb/s. The device features a CODEC port interface compatible with AC'97 and I2S protocols, four DMA channels for audio streaming, and an adaptive clock generator. It operates on a 3.3V core with 5V-compatible I/O buffers and is housed in a 52-pin TQFP package.

Feature Summary

• Integrates an 8052 microcontroller with 4KB ROM and 8KB RAM for firmware execution
• Supports up to seven IN and seven OUT endpoints for control, interrupt, bulk, and isochronous transfers
• CODEC port interface configurable for AC'97 1.X/2.X or I2S serial formats
• Four-channel DMA controller dedicated to streaming USB isochronous data packets

Applications

• Digital speaker systems requiring USB audio streaming
• USB peripheral interfaces for isochronous data transfer
• Audio devices utilizing AC'97 or I2S codec connections

Procurement Notes

Verify the specific suffix 'CPAH' against the manufacturer's current ordering information to confirm package type and temperature range. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements associated with this legacy component before finalizing procurement plans.

Selection Notes

Select this component for designs requiring integrated USB-to-audio streaming capabilities without an external host processor. Ensure the application utilizes a 6 MHz crystal for the internal oscillator. Verify that the target system supports the required 3.3V logic levels for the core and handles the 5V compatibility on the CODEC port interface signals.

Part Context

The TUSB3200 belongs to Texas Instruments' USB streaming controller family, specifically engineered for audio applications. It bridges USB connectivity with standard audio codecs via its C-Port. The CP prefix typically denotes commercial temperature range variants within the TUSB3200 series, while PAH indicates the 52-pin Thin Quad Flat Package.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Designers should consult the official datasheet for recommended alternatives or evaluate newer generations of USB audio controllers from Texas Instruments for pin-compatible or functionally equivalent replacements.
