MAX31826
1-Wire Digital Temperature Sensor
with 1Kb Lockable EEPROM
? Maxim Integrated Products 1
General Description
The MAX31826 digital thermometer provides 12-bit
temperature measurements and communicates over a
1-Wire
M
bus that by definition requires only one data line
(and ground) for communication with a central microcon-
troller. It has a -55NC to +125NC operating temperature
range and is accurate to Q0.5NC over the -10NC to +85NC
range. In addition, the device can derive power directly
from the data line ( parasite power ), eliminating the
need for an external power supply.
Each device has a unique 64-bit serial code, which
allows multiple devices to function on the same 1-Wire
bus. Therefore, it is simple to use one microcontroller
(the master device) to control many devices distributed
over a large area. The device includes 128 bytes (1Kb)
of EEPROM for storage of system data. The EEPROM
can be locked to permanently prevent any further data
writes. Four location address inputs simplify mapping of
individual devices to specific locations.
