    关于DS2490单片机/IC芯片
　　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.
　　DS2490 FEATURES：
　　•Communicates at regular and Overdrive 1-Wire speeds
　　•Supports 12V EPROM programming and stiff 5V pullup for crypto iButton, sensors and EEPROM
　　•Slew rate controlled 1-Wire timing and active pullup to accommodate long lines and reduce radiation
　　•Programmable 1-Wire timing and driver characteristics accommodate a wide range of MicroLAN configurations at regular speed
　　•Smart 1-Wire protocol combines data and control information without requiring extra pins
　　•High-speed 12 Mbps USB interface
　　•Integrated USB-compliant transceiver
　　•Supports USB remote wakeup to resume a suspended host system
