●FAST-MODE and STANDARD-MODE
FAST-MODE and STANDARD-MODE are of same operations, and mode is changed. They are distinguished by operating
speeds. 100kHz operation is called STANDARD-MODE, and 400kHz operation is called FAST-MODE. This operating
frequency is the maximum operating frequency, so 100kHz clock may be used in FAST-MODE. At VCC =2.5V to 5.5V,
400kHz, namely, operation is made in FASTMODE. (Operation is made also in STANDARD-MODE.)
●Sync Data Input / Output Timing
○Input read at the rise edge of SCL
○Data output in sync with the fall of SCL
Figure 1-(a) Sync data input / output timing
Figure 1-(b) Start-stop bit timing
Figure 1-(c) Write cycle timing
Figure 1-(d) WP timing at write execution
○At write execution, in the area from the D0 taken clock rise of the first
DATA(1), to tWR, set WP=“LOW”.
○By setting WP “HIGH” in the area, write can be cancelled.
When it is set WP=“HIGH” during tWR, write is forcibly ended, and data of
address under access is not guaranteed, therefore write it once again.
