DS620 Digital Thermometer and Thermostat

14 of 15

ACK

DS620 generates acknowledge.

xxxxxxx1b

Bus master writes to the configuration register putting

the DS620 back in 1SHOT mode: 1SHOT = 1.

START

Bus master generates a repeated start condition.

<address, 0> Bus master sends DS620 address, R/W = 0.

ACK

DS620 generates acknowledge.

48h

Master sends COPY DATA command to DS620 to

copy data in from SRAM memory to EEPROM memory.

ACK

DS620 generates acknowledge.

START

Bus master generates a repeated start condition.

<address, 0> Bus master sends DS620 address, R/W = 0.

ACK

DS620 generates acknowledge.

22h

Bus master sends a STOP CONVERT command to

stop the DS620 from continuously converting

temperature. NOTE: Bus master should ensure that

EEPROM copy operation is complete before executing

the STOP CONVERT command by either waiting 10ms

from the time of the COPY DATA command or

checking the NVB bit in configuration register

ACK

DS620 generates acknowledge.

STOP

Bus master sends STOP condition to end

communication with DS620. (The bus master could

send a repeated start condition if additional

communication with the DS620 is desired.)

START

Bus master initiates a START condition.

<address, 0> Bus master sends DS620 address, R/W = 0.

ACK

DS620 generates acknowledge bit.

51h

Master sends START CONVERT command to DS620

to start temperature conversions.

ACK

DS620 generates acknowledge bit and begins

conversions.

START

Bus master generates a repeated start condition.

<address, 0> Bus master sends DS620 address, R/W = 0.

ACK

DS620 generates acknowledge.

ACh

Bus master sends the address location of the MSb of

the configuration register (contains the 1SHOT bit).

This writes to the SRAM location corresponding the

EEPROM location.

ACK

DS620 generates acknowledge.

xxxxxxx1b

Bus master writes to the configuration register putting

the DS620 in 1SHOT mode: 1SHOT = 1.

ACK

DS620 generates acknowledge.

START

Bus master generates a repeated start condition.

<address, 0>

Bus master sends DS620 address, R/W = 0.

ACK

DS620 generates acknowledge.

48h

Master sends COPY DATA command to DS620 to

copy data in from SRAM memory to EEPROM

memory.
