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
TM
bus
Unique, factory–lasered and tested 64–bit registra-
tion 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
TM
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, and data to a single pin
Zero standby power required
Directly connects to a single port pin of a microproces-
sor and communicates at up to 16.3k bits/s
Pulse width measurement determines 1s or 0s
Power derived from data line

DESCRIPTION
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. Power for reading and writing the device is
