DS1626/DS1726  
CPU BIT AND STAND-ALONE THERMOSTAT OPERATION  
In stand-alone thermostat mode, DS1626/DS1726 thermostat functionality can be used without requiring  
a microcontroller to start/stop temperature conversions. The CPU bit in the configuration register  
determines if stand-alone mode is enabled.  
When CPU = 1 stand-alone mode is disabled, and the only way to start/stop temperature conversions is  
by using a microcontroller to transmit Start Convert T and Stop Convert T commands, respectively.  
Stand-alone mode is enabled when CPU = 0. In this mode, when RST = 0 the CLK/CNV pin operates as  
a control signal to start and stop temperature measurements. Driving CLK/CNV low initiates continuous  
temperature conversions that will continue until CLK/CNV is brought high again. If the CLK/CNV pin is  
driven low and then returned to a high state in less than 10ms, only one temperature conversion will be  
performed after which the DS1626/DS1726 will return to a low-power idle state (i.e., one-shot operation).  
Note that when stand-alone mode is enabled, the 1SHOT bit in the configuration register is ignored, and  
only the CLK/CNV signal determines whether continuous or one-shot conversions take place.  
Since TH, TL, and the CPU bit are stored in EEPROM, the DS1626/DS1726 can be preprogrammed for  
stand-alone operation. If desired, the CLK/CNV and RST pin can be connected to GND so the  
DS1626/DS1726 will automatically begin taking temperature measurements at power-up  
Normal bus communication with the DS1626/DS1726 can still take place in stand-alone mode when  
RST = 1. When communication is initiated, stand-alone conversions are automatically halted. If during  
the bus communication continuous temperature conversions are started using the Start Convert T  
command, they can only be stopped by issuing a Stop Convert T command.
