USB Overview
The M30245 group is a single-chip PC peripheral microcontroller that is compliant with the Universal Serial Bus (USB)
Version 2.0 specification for full-speed USB operation (12Mbps). This device provides an interface between a USB-
equipped host computer and PC peripherals such as telephones, audio systems, and digital cameras. The M30245
architectural overview is shown in Figure 1.4.
The USB function control unit of the M30245 group supports full-speed operation and all four data transfer types
listed in the USB specification. Each transfer type is used for controlling a different set of PC peripherals.
• Isochronous transfers provide guaranteed bus access, a constant data rate, and error tolerance for devices such
as computer-telephone integration (CTI) and audio systems.
• Interrupt transfers are designed to support human input devices (HID) that communicate small amounts of data
infrequently.
• Bulk transfers are necessary for devices such as digital cameras and scanners that communicate large
amounts of data to the PC as bus bandwidth becomes free.
• Control transfers are supported and are useful for bursty, host-initiated type communication where bus manage-
ment is the primary concern.
