DS1626/DS1726 COMMAND SET
The DS1626/DS1726 command set is detailed below:
Start Convert T
Initiates temperature conversions. If the DS1626/DS1726 are in one-shot mode (1SHOT = 1), only one
conversion will be performed. If the devices are in continuous mode (1SHOT = 0), continuous
conversions will be performed until a Stop Convert T command is issued.
Stop Convert T
Stops temperature conversions when the devices are in continuous conversion mode (1SHOT = 0).
Read Temperature
Reads the last converted temperature value from the temperature register.
Read TH
Reads the 12-bit T
Read TL
Reads the 12-bit T
Write TH*
Writes the 12-bit T
Write TL*
Writes the 12-bit T
Read Config
Reads the 1-byte configuration register.
Write Config*
Writes the 1-byte configuration register.
Software POR
Initiates a software power-on reset (POR), which stops temperature conversions and resets all registers
and logic to their power-up states. The software POR allows the user to simulate cycling the power
without actually powering down the device.
*After issuing a write command, no further writes should be requested for at least 10ms due to the
EEPROM write cycle time.
