DS2490規(guī)格書詳情
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.
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
