Dallas Semiconductor introduced its first 1-Wire product with external address inputs, which can be used to identify and configure the physical location of the device.

The new DS28E04-100 is a 4Kb 1-Wire EEPROM product that provides two GPIO ports that can be configured as level input/output or pulse output with 250ms nominal pulse duration. The address-setting capability with EEPROM and the flexible GPIO ports make the device optimally suited for identification, location, monitoring and system control in rack-based multicard environments such as cellular base stations, central office switches and enterprise servers, the company said.

The DS28E04-100 is completely powered and operated through Dallas' 2-contact 1-Wire interface, which can support line configurations consisting of hundreds of 1-Wire devices connected to tens of meters of low-cost wiring.

The device operates from 2.8V to 5.25V over the -40C to 85C temperature range, and is available in a 16-pin SO package.
