Abstract: This paper designs and implements an Universal Serial Bus(USB)1.1 controller. It supports control, interrupt and bulk mode at full speed. The number of the endpoints of this IP is configurable. The IP works in a security chip and it breaks some of the bottleneck of the chip I/O communications. An FPGA verification platform is built with this USB 1.1 device IP and MCU 8051, and it can communicate with the PC. Other function modules in the security chip are tested on this platform.

Key words: Universal Serial Bus(USB), FPGA verification, SFR bus
