FEATURES PIN ASSIGNMENT
• Unique 1–WireTM interface requires only one port pin
for communication
• Multidrop capability simplifies distributed temperature
sensing applications
• Requires no external components
• Can be powered from data line
• Zero standby power required
• Measures temperatures from –55°C to +125°C in
0.5°C increments. Fahrenheit equivalent is –67°F to
+257°F in 0.9°F increments
• Temperature is read as a 9–bit digital value.
• Converts temperature to digital word in 200 ms (typ.)
• User–definable, nonvolatile temperature alarm set-
tings
• Alarm search command identifies and addresses
devices whose temperature is outside of pro-
grammed limits (temperature alarm condition)
• Applications include thermostatic controls, industrial
systems, consumer products, thermometers, or any
thermally sensitive system
PIN DESCRIPTION
GND – Ground
DQ – Data In/Out
VDD – Optional VDD
NC – No Connect
DESCRIPTION
The DS1820 Digital Thermometer provides 9–bit tem-
perature readings which indicate the temperature of the
device.
Information is sent to/from the DS1820 over a 1–Wire
interface, so that only one wire (and ground) needs to be
connected from a central microprocessor to a DS1820.
Power for reading, writing, and performing temperature
conversions can be derived from the data line itself
with no need for an external power source.
Because each DS1820 contains a unique silicon serial
number, multiple DS1820s can exist on the same
1–Wire bus. This allows for placing temperature sen-
sors in many different places. Applications where this
feature is useful include HVAC environmental controls,
sensing temperatures inside buildings, equipment or
machinery, and in process monitoring and control.
