EZ-USB SX2™ | Cypress Semiconductor


The EZ-USB SX2 is a Hi-Speed USB 2.0 data pipe designed to work with any external master, such as standard microprocessors, DSPs, ASICs, and FPGAs to enable USB 2.0 support for any peripheral design. SX2 has a built-in USB transceiver and serial interface engine (SIE), along with a command decoder to send and receive USB data. The controller has four endpoints that share a 4-KB FIFO space for maximum flexibility and throughput. SX2 has three address pins and a selectable 8- or 16- bit data bus for command and data input or output.
