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

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 T_H, T_L, 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.
