Introduction

The EZ-USB SX2™ USB interface device is 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 Seria Interface Engine (SIE), along with a command decoder for sending and receiving USB data. The controller has four endpoints that share a 4 KB FIFO space for maximum flexibility and throughput, and Control Endpoint 0. SX2 has three address pins and a selectable 8- or 16- bit data bus for command and data input or output.
