Product Summary

The DS2401+ enhanced Silicon Serial Number is a low-cost, electronic registration number that provides an absolutely unique identity which can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller). The DS2401+ consists of 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).

Parametrics

Absolute maximum ratings: (1)Voltage on any Pin Relative to Ground: -0.5V to +7.0V; (2)Operating Temperature Range: -40℃ to +85℃; (3)Storage Temperature Range: -55℃ to +125℃; (4)Soldering Temperature: See J-STD-020A Specification.

Features

Features: (1)Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester); guaranteed no two parts alike; (2)Built-in multidrop controller ensures compatibility with other 1-Wire Net products; (3)8-bit family code specifies DS2401communications requirements to reader; (4)Presence Pulse acknowledges when the reader first applies voltage; (5)Low-cost TO-92, SOT-223, and TSOC surface mount packages; (6)Reduces control, address, data, and power to a single pin; (7)Zero standby power required; (8)Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbits/s.
