TUSB3200CPAHG4

Overview

The TUSB3200CPAHG4 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, handling USB control, interrupt, bulk, and isochronous transactions. The device supports up to seven IN and seven OUT endpoints with programmable buffer sizes. It features a CODEC Port Interface (C-Port) configurable for AC’97 or I²S protocols, connected via a four-channel DMA controller. An on-chip PLL generates clocks from a 6 MHz crystal input, supporting asynchronous, synchronous, and adaptive synchronization modes for audio streaming.

Feature Summary

• Integrates an 8052 MCU core with 4KB boot loader ROM and 8KB application RAM.
• Supports USB Specification 1.1 and Audio Class 1.0 at 12 Mb/s full speed.
• Includes a CODEC Port Interface compatible with AC’97 1.X/2.X and I²S formats.
• Features a four-channel DMA controller for streaming isochronous data between USB and CODEC ports.

Applications

• Digital speaker systems requiring USB-to-audio streaming.
• USB peripheral devices utilizing isochronous data transfer.
• Audio interfaces connecting host PCs to CODEC hardware.

Procurement Notes

Verify the component status as discontinued based on available distributor records. Confirm the G4 suffix indicates lead-free packaging compliant with RoHS standards. Ensure the PAH package designation corresponds to the 52-pin TQFP form factor required for the design.

Selection Notes

Select this component for designs requiring integrated USB streaming capabilities without external controllers. Verify that the system can accommodate the 3.3V core voltage and 5V-compatible I/O buffers for the CODEC interface. Ensure the application utilizes an external EEPROM for firmware storage, as the internal ROM only contains the boot loader.

Part Context

The TUSB3200 belongs to Texas Instruments' TUSB series of USB streaming controllers. The CPAH variant denotes the 52-pin TQFP package, while the G4 suffix typically signifies lead-free construction. This device serves as a bridge between USB hosts and audio CODECs, simplifying the implementation of USB audio peripherals.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is listed as discontinued, alternative solutions require evaluating newer USB audio controller families from Texas Instruments or other manufacturers with similar endpoint and codec interface configurations.
