Interface - Controllers: TAS1020APFB Application Field and Working Principle

The TAS1020APFB is a high-speed, high-bandwidth, integrated interface controller that enables systems to interface easily, quickly and cost-effectively to host devices. This device is designed for use in a wide range of applications, including Set-Top-Box, DVD players, PC motherboards, storage devices, and medical instrumentation, as well as a range of embedded applications.

The TAS1020APFB integrates two high-speed Universal Serial Bus (USB 2.0) ports, one or two Serial ATA ports, and one Serial Peripheral Interface (SPI) port. It is ideal for applications that demand high-speed and/or low cost system integration. The USB 2.0 ports operate at 480 Mbps and are fully compliant with USB 2.0\'s device and host protocols. The SATA ports provide a maximum burst rate of 150 Mbps. The SPI port is also capable of transfer rates of up to 43 Mbps.

The TAS1020APFB is a low-power device that typically consumes less than 0.5 watts in operation. It features on-chip power management, system thermal management, and robust grounding in order to ensure reliable performance. Protection functions include ESD, surge, overload and short-circuit protection. The device also incorporates four I/O digital pins for parameter memory locks and a flexible power-on-reset delay.

The working principle of the TAS1020APFB is based on the shared memory architecture. This architecture utilizes a single memory pool for both the host and device memory configurations. Data is transferred between the host and device by means of direct memory access (DMA). The TAS1020APFB is capable of both read and write operations and can support transfer sizes of up to 64KB in both directions.

The TAS1020APFB also offers several advanced features that include support for concurrent read/write operations, support for high-speed burst transfers, buffering of bursts requests, USB and SATA port reset capability, and hot-swap support. These features allow for higher system performance and maximum compatibility.

The TAS1020APFB provides a complete, low-cost solution for systems requiring integration of a high-speed, low-cost interface controller. With its wide range of applications, it is an ideal solution for embedded, PC, storage, medical and consumer electronic applications.
