W712 USB Device Controller
0.5µm Technology Mega Macrofunction
DESCRIPTION
The Universal Serial Bus (USB) Device Controller Mega Macrofunction is a featured element in Oki’s
0.5µm Sea of Gates (SOG) and Customer Structured Array (CSA) families. Oki's USB mega macrofunction
provides a USB interface, control/status block, FIFO control, and application interface in two highly inte-
grated submodules for system design interfaces based on the USB protocol. The submodule partitioning
allows custom configurations to be easily developed. The USB mega macrofunction connects an industry
standard USB interface with a microprocessor-style parallel application interface. This straightforward
interface permits easy integration of the USB mega macrofunction to the target application. Using Oki’s
USB mega macrofunction, designers can reduce development time, risk, and introduce their USB based
products to market faster. Oki’s W712 USB Device Controller mega macrofunction provides a complete
USB device interface solution and is fully compliant with the Universal Serial Bus 1.0 specification. For
more details on the Universal Serial Bus 1.0 specification, refer to www.usb.org.
