DS2490規(guī)格書詳情
DESCRIPTION
The DS2490 is a bridge chip that enables communication between a USB host system and a 1-Wire bus. It provides regular, overdrive, and flexible 1-Wire communication speeds and a full-speed 12Mbps 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 stiff 5V pullup for EEPROM, sensors, and crypto iButton?
● Slew rate controlled 1-Wire timing and active pullup to accommodate long 1-Wire network lines and reduce radiation
● Programmable 1-Wire timing and driver characteristics accommodate a wide range of 1-Wire network configurations
● Low- to high-level command types, including macros, for generating 1-Wire communication
● Crystal oscillator timebase provides precision timed 1-Wire waveforms
● High-speed 12Mbps Universal Serial Bus (USB) interface
● Integrated USB-compliant transceiver
● Supports USB remote wake-up from a 1-Wire device event to resume a suspended host system
● 0℃ to +70℃ operating temperature range
