DESCRIPTION
The DS2490 is a bridge chip that enables communication between the Universal Serial Bus (USB) and a
1-Wire bus. It provides regular, overdrive and flexible 1-Wire communication speeds and a full-speed 12
Mbps connection to USB. USB vendor-specific commands defined in this specification are used to
control the DS2490 and communicate with attached 1-Wire devices. A functional block diagram of the
DS2490 is shown in Figure 1.
