Digital thermometer measures temperatures
from -55°C to +100°C in typically 0.2
seconds
Zero standby power
0.5°C resolution, digital temperature reading
is two’s complement of °C value
Access to internal counters allows increased
resolution through interpolation
Reduces control, address, data, and power to
a single data contact
8-bit device-generated CRC for data integrity
8-bit family code specifies DS1920
communications requirements to reader
Special command set allows user to skip
ROM section and do temperature
measurements simultaneously for all devices
on the bus
2 bytes of EEPROM to be used either as
alarm triggers or user memory
Alarm search directly indicates which device
senses alarming temperatures
