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.
