USB Streaming Controller (STC)

Check for Samples: TUSB3200A

Introduction

The TUSB3200A integrated circuit (IC) is a universal serial bus (USB) peripheral interface device

designed specifically for applications that require isochronous data streaming. Applications include digital

speakers, which require the streaming of digital audio data between the host PC and the speaker system

via the USB connection. The TUSB3200A device is fully compatible with the USB Specification Version

1.1 and the USB Audio Class 1.0 Specification.

The TUSB3200A uses a standard 8052 microcontroller unit (MCU) core with on-chip memory. The MCU

memory includes 4K bytes of program memory ROM that contains a boot loader program. At initialization,

the boot loader program downloads the application program code to an 8K RAM from a nonvolatile

memory on the printed-circuit board (PCB). The MCU handles all USB control, interrupt and bulk endpoint

transactions. In addition, the MCU can handle USB isochronous endpoint transactions.

The USB interface includes an integrated transceiver that supports 12 Mb/s (full speed) data transfers. In

addition to the USB control endpoint, support is provided for up to seven in endpoints and seven out

endpoints. The USB endpoints are fully configurable by the MCU application code using a set of endpoint

configuration blocks that reside in on-chip RAM. All USB data transfer types are supported.

The TUSB3200A device also includes a codec port interface (C-Port) that can be configured to support

several industry standard serial interface protocols. These protocols include the audio codec (AC) '97

Revision 1.X, the audio codec (AC) '97 Revision 2.X and several Inter-IC sound (I2S) modes.

A direct memory access (DMA) controller with four channels is provided for streaming the USB

isochronous data packets to/from the codec port interface. Each DMA channel can support one USB

isochronous endpoint.

An on-chip phase lock loop (PLL) and adaptive clock generator (ACG) provide support for the USB

synchronization modes, which include asynchronous, synchronous and adaptive.

Other on-chip MCU peripherals include an Inter-IC control (I2C) serial interface, two general-purpose

input/output (GPIO) ports, and a pulse width modulation (PWM) output.

The TUSB3200A device is implemented in a 3.3-V 0.25 µm CMOS technology. In addition, the use of 5-V

compatible input/output buffers for the codec port interface allows the TUSB3200A device to be connected

to either 3.3-V or 5-V codec devices.
