Product Details

The DS2411 silicon serial number is a low-cost, electronic registration number with external power supply. It provides an absolutely unique identity that can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller). The DS2411's registration number is a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code (01h). Data is transferred serially through the Maxim 1-Wire® protocol. The external power supply is required, extending the operating voltage range of the device below typical 1-Wire devices.

Key Features

  • Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code Plus 48-Bit Serial Number Plus 8-Bit CRC Tester); Guaranteed No Two Parts Alike
  • Standby Current <1µA
  • Built-In Multidrop Controller Enables Multiple DS2411s to Reside on a Common 1-Wire Network
  • Multidrop Compatible with Other 1-Wire Products
  • 8-Bit Family Code Identifies Device as DS2411 to the 1-Wire Master
  • Low-Cost TSOC, SOT23-3, and Flip-Chip Surface-Mount Packages
  • Directly Connects to a Single-Port Pin of a Microprocessor and Communicates at up to 15.4kbps
  • Overdrive Mode Boosts Communication Speed to 125kbps
  • Operating Range: 1.5V to 5.25V, -40°C to +85°C

Applications/Uses

  • Accessory/Peripheral Identification
  • Equipment Registration
  • Module Identification
  • Network-Node Identification
  • PCB Identification
  • Reference Design License Management

Evaluation Board

DS9090EVKIT

$47.25

Description

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.
