Firma Dallas-Maxim produkuje układ DS2490 umożliwiający konwersję USB na transmisję 1-Wire. Istnieje pełna kompatybilność z USB1.1, a przepływność danych dochodzi do 12Mbps. Blokowy schemat możemy podzielić na trzy moduły: kontroler USB, moduł konwersji USB na 1-Wire, kontroler 1-Wire.
Pozostałe parametry:
Communicates at regular and overdrive 1-WireR speeds
Supports 12V EPROM programming and stiff 5V pullup for EEPROM, sensors, and crypto iButtonR
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
0C to +70C operating temperature range
Package SO16, CSP2490

Fajne? Ranking DIY
) wlasna plytke w EAGLE i miesci sie ona go gniazdka telefonicznego, posiada LED, mniejsza chyba, SMD i wyprowadzenia zgodne z DS9490.
