Product Summary

The DS2401 is a silicon serial number. 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). Data is transferred serially via the 1-Wire protocol which requires only a single data lead and a ground return.

Parametrics

DS2401 absolute maximum ratings: (1)Voltage on any Pin Relative to Ground: -0.5V to +7.0V; (2)Operating Temperature: -40℃ to +85℃; (3)Storage Temperature: -55℃ to +125℃; (4)Soldering Temperature: 260℃ for 10 seconds.

Features

DS2401 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 MicroLAN products; (3)8-bit family code specifies DS2401 communications 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.
