UPD720122

DATA SHEET MOS Integrated Circuit µPD720122 USB2.0 Generic Device Controller The µPD720122 is USB2.0 Generic Device Controller, which combines 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 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. Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing. µPD720122 User’s Manual: S15829E FEATURES Complaint with USB2.0 specification (Maximum data transferring rate: 480 Mbps) USB2.0 certified (TestID=40000822) High(480Mbps) / Full(12Mbps)- Speed support and switch automatically Easy to design NEC Electronics ASIC Generic USB2.0 Device Controller Two Bulk End-points and One Interrupt End-point Performed Data Local Bus independent from CPU bus.
