Part Details

  • Open drain PIO pins are controlled and their logic level can be determined over 1-Wire bus for closed-loop control
  • Replaces and is fully compatible with DS2407 but no user-programmable power-on settings and no Hidden Mode
  • PIO channel A sink capability of 50mA at 0.4V with soft turn-on; channel B 8mA at 0.4V
  • Maximum operating voltage of 13V at PIO-A, 6.5V at PIO-B
  • 1024 bits user-programmable OTP EPROM
  • User-programmable status memory to control the device
  • Multiple DS2406's can be identified on a common 1-Wire bus and be turned on or off independently of other devices on the bus
  • Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures error-free selection and absolute identity because no two parts are alike
  • On-chip CRC16 generator allows detection of data transfer errors
  • Built-in multidrop controller ensures compatibility with other 1-Wire net products
  • Reduces control, address, data, programming and power to a single data pin
  • Directly connects to a single port pin of a microprocessor and communicates at up to 16.3 kbits/s
  • Supports Conditional Search with user-selectable condition
  • VCC bondout for optional external supply to the device (TSOC package only)
  • 1-Wire communication operates over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C
  • Low cost TO-92, 6-pin TSOC and Flip Chip surface mount package

Product Details

The DS9090EVKIT evaluation system (EV system) consists of a DS9490+ USB-to-1-Wire®/iButton® adapter for PC connectivity, a DS9120P+ socket board with RJ11 cable, and seven different 1-Wire devices. This EV system provides the special hardware and software system to exercise the features of 1-Wire devices with memory or PIO/switches, except 1-Wire EPROM devices. (EPROM devices such as the DS2502 and DS2506 require a different adapter (DS9481R-3C7) to perform an EPROM write. This adapter can be purchased separately.) 1-Wire EPROM devices are available for sampling.

The EV system software consists of the OneWireViewer (a Java® program) that runs under Windows ® OS and comes as part of the 1-Wire drivers installation package.
