The TUSB3200 is a USB Streaming Controller (STC) data manual from Texas Instruments.
The TUSB3200 is a USB peripheral interface IC designed for isochronous data streaming applications such as digital speakers. It integrates a USB transceiver, an 8052‑core MCU, a CODEC port interface, and a DMA controller, all implemented in a 3.3‑V CMOS process.
The manual details the device architecture, electrical characteristics, pin assignments for normal and external‑MCU modes, mechanical dimensions, and packaging information, along with register maps and programming guidelines.
