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 TH register.

Read TL

A2h 1010 0010

Reads the 12-bit TL register.

Write TH*

01h 0000 0001

Writes the 12-bit TH register.

Write TL*

02h 0000 0010

Writes the 12-bit TL 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.
