dedicated LSI for a HUB connected to a universal serial bus (USB) system. It is an upgrade of NEC’s µPD72011. It complies with USB specification revision 1.1. By putting descriptors into ROM, information such as a user’s vendor ID can be implemented in the chip. FEATURES { Compliant with Chapter 11 (HUB Specifications) of USB Specification 1.1. { Descriptors into ROM • The user can customize the vendor ID and product ID by using Mask ROM option. { Supports 5 kinds of string descriptors (for Mask ROM code product only) { On-chip sequencer • There is an on-chip descriptor and request response sequencer.
