DS2490 - USB to 1-Wire Bridge Chip

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.

Features

  • Communicates at regular and overdrive 1Wire® 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 pro.
