The µPD720130 is designed to perform a bridge between USB 2.0 and ATA/ATAPI. The µPD720130 complies with the Universal Serial Bus Specification Revision 2.0 full-/high-speed signaling and works up to 480 Mbps. The µPD720130 is integrated CISC processor, ATA/ATAPI controller, endpoint controller (EPC), serial interface engine (SIE), and USB2.0 transceiver into a single chip. The USB2.0 protocol and class specific protocol (bulk only protocol) are handled by USB2.0 transceiver, SIE, and EPC. And the transport layer is performed by V30MZ CISC processor which is in the µPD720130. The software to control the µPD720130 is located in an embedded ROM. In the future, the µPD720130 will be released to support external Flash Memory / EEPROM™ option to update function by firmware.
