FEATURES
§
Open drain PIO pin is controlled by
matching 64-bit, laser-engraved registration
number associated with each device
§
Logic level of open drain output can be
determined over 1-Wire bus for closed-loop
control
§
PIO pin sink capability is greater than 4 mA
at 0.4V
§
Multiple DS2405’s can be identified on a
common 1-Wire bus and be turned on or off
independent of other devices on the bus
§
Unique, factory-lasered and tested 64-bit
registration number (8-bit family code +48-
bit serial number +8-bit CRC tester) assures
absolute identity because no two parts are
alike
§
Built-in multidrop controller ensures
compatibility with other MicroLAN products
§
Reduces control, address, data, and power to
a single data pin
§
Directly connects to a single port pin of a
microprocessor and communicates at up to
16.3 kbits/s
§
8-bit family code specifies DS2405
communications requirements to reader
§
8-bit cyclic redundancy check ensures error-
free selection
§
Zero standby power required
§
Low cost TO-92, SOT-223, or 6-pin TSOC
surface mount package
§
1-Wire communication operates over a wide
voltage range of 2.8V to 6.0V from -40°C to
+85°C
