General Description
The USB2 Controller is a single chip that provides the capability to interface to a peripheral
device to the Universal Serial Bus (USB).
processor, mask ROM, RAM buffer, clock generator, and a series of interfaces. The interfaces,
shown in the block diagram below, provide control and data access, and USB data reception and
transmission. The SIE is fully compatible with the USB specification. The USB2 has been
specifically designed to provide a simple and fast method of designing interfaces for peripheral
devices to the USB port. The USB2 is ideally suited to interface the USB to a wide variety of
peripheral devices such as keyboards, cameras, scanners, communications, and other peripheral
devices. Should analog capability be required, the USB3 contains an eight-channel 10-bit analog
to digital converter.
