USB Streaming Controller (STC)

The TUSB3200 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 USB3200 device is fully compatible with the USB Specification Version 1.1 and the USB Audio Class Specification.
The TUSB3200 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 TUSB3200 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 TUSB3200 device is implemented in a 3.3-V 0.25um CMOS technology. In addition, the use of 5-V compatible input/output Buffers for the CODEC port Interface allows the TUSB3200 device to be connected to either 3.3-V or 5-V CODEC devices.
