Product Summary

The DS2401+ is a Silicon Serial Number. It 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). The applications of it are PCB Identification, Network Node ID, Equipment Registration.

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)Upgrade and drop-in replacement for DS2400:Extended 2.8 to 6.0 voltage range,Multiple DS2401s can reside on a common 1-Wire bus; (2)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; (3)Built-in multidrop controller ensures compatibility with other MicroLAN products; (4)8-bit family code specifies DS2401 communications requirements to reader; (5)Presence Pulse acknowledges when the reader first applies voltage; (6)Low-cost TO-92, SOT-223 and TSOC surface mount packages; (7)Reduces control, address, data, and power to a single pin; (8)Zero standby power required; (9)Directly connects to a single port pin of a microprocessor and communicates at up to 16.3 kbits/s; (10)TO-92 tape & reel version with leads bent to 100 mil spacing (default) or with straight leads.
