NOTES:
1.
Data direction depends upon R/
bit in the 2-wire control byte.
2.
When accessing (reading from or writing to) addressed SRAM in the page mode, the address
pointer will automatically roll from the most significant byte to the least significant byte following
the ACK of the most significant byte.
3.
In continuous conversion mode, a Stop Convert T command will halt continuous conversion. To
restart, the Start Convert T command must be issued. In one-shot mode, a Start Convert T
command must be issued for every temperature reading desired.
4.
If the user only desires 8-bit thermometer resolution, the master need only read 1 data byte, and
follow with a NACK and STOP. If higher resolution is required, 2 bytes must be read.
5.
Writing to E
2
registers typically requires 10ms at room temperature (50ms max). After issuing a
write command, no further writes should be requested for 50ms. E
2
writes should only occur
under the conditions 2.7V d V
DD
d 5.5V and 0癈 d T
J
d 70癈.
