µPD720122
USB2.0 Generic Device Controller
The µPD720122 is USB2.0 Generic Device Controller, which bines the NEC Electronics USB2.0 PHY and Endpoint Controller. The Controller has certified by USB Implementers Forum. End-point Controller has banked two Bulk Endpoint 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 pletely on an NEC Electronics ASIC core, so µPD720122 is suitable to design for the...
