The μPD720122 is USB2.0 Generic Device Controller, which combines the NEC Electronics USB2.0 PHY and End point Controller. The Controller has certified by USB Implementers Forum. End-point Controller has banked two Bulk End point and one Interrupt End-point, and selectable three general CPU bus-types, suitable for designing various USB device. The controller has the external local bus, that enables to perform high speed data transferring when CPU is accessing to the controller. These IP Blocks in the controller are based completely on an NEC Electronics ASIC core, so μPD720122 is suitable to design for the prototype system that are intended to design ASIC in the future.
