1-3
The 7600 series, an enhanced family of CMOS 8-bit microcontrollers, offers high-speed operation at
low voltage, large internal-memory options, and a wide variety of standard peripherals. The series is
code compatible with the M38000, M37200, M37400, and the M37500 series, and provides many
performance enhancements to the instruction set.
This device is a single chip PC peripheral microcontroller based on the Universal Serial Bus (USB)
Version 1.0 specification. This device provides data exchange between a USB-equipped host computer
and PC peripherals such as telephones, audio systems and digital cameras. See Figure 1-1 for an
application system diagram.
The USB function control unit can support all four data transfer types listed in the USB specification:
Control, Isochronous, Interrupt, and Bulk. 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. Finally, control transfers
are supported and are useful for bursty, host-initiated type communication where bus management is the
primary concern.
