All rights reserved. ● FAST-MODE and STANDARD-MODE FAST-MODE and STANDARD-MODE are of same actions, and mode is changed. They are distinguished by action speeds. 100kHz action is called STANDARD-MODE, and 400kHz action is called FAST-MODE. This action frequency is the maximum action frequency, so 100kHz clock may be used in FAST-MODE. At VCC=2.5V~5.5V , 400kHz, namely, action is made in FASTMODE. (Action 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 Fig.1-(a) Sync data input / output timing Fig.1-(b) Start-stop bit timing Fig.1-(c) Write cycle timing Fig.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.
