FEATURES
§ 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
§ 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
§ Built-in multidrop controller ensures
compatibility with other MicroLAN
products
§ 8-bit family code specifies DS2401
communications requirements to reader
§ Presence Pulse acknowledges when the
reader first applies voltage
§ Low-cost TO-92, SOT-223 and TSOC
surface mount packages
§ Reduces control, address, data, and power to
a single pin
§ Zero standby power required
§ Directly connects to a single port pin of a
microprocessor and communicates at up to
16.3 kbits/s
§ TO-92 tape & reel version with leads bent to
100 mil spacing (default) or with straight
leads (DS2401T-SL)
§ Applications
- PCB Identification
- Network Node ID
- Equipment Registration
§ Operates over industrial temperature range of
-40°C to +85°C
