DS1626/DS1726
DS1626/DS1726 COMMAND SET
The DS1626/DS1726 command set is detailed below:
Start Convert T 51h 0101 0001
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 22h 0010 0010
Stops temperature conversions when the devices are in continuous conversion mode (1SHOT = 0).
Read Temperature
AAh 1010 1010
Reads the last converted temperature value from the temperature register.
Read TH
A1h 1010 0001
Reads the 12-bit T_H register.
Read TL
A2h 1010 0010
Reads the 12-bit T_L register.
Write TH*
01h 0000 0001
Writes the 12-bit T_H register.
Write TL*
02h 0000 0010
Writes the 12-bit T_L register.
Read Config
ACh 1010 1100
Reads the 1-byte configuration register.
Write Config*
0Ch 0000 1100
Writes the 1-byte configuration register.
Software POR 54h 0101 0100
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.
