µ
PD720130
USB2.0 to IDE Bridge
The
µ
PD720130 is designed to perform a bridge between USB 2.0 and ATA/ATAPI. The
µ
PD720130 complies
with the Universal Serial Bus Specification Revision 2.0 full-/high-speed signaling and works up to 480 Mbps. The
µ
PD720130 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
µ
PD720130. The software to control the
µ
PD720130 is located in an embedded ROM. In
the future, the
µ
PD720130 will be released to support external Flash Memory / EEPROM™ option to update function
by firmware.
Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing.
