*1 : tD after read cycle normally equals 40ns. But in QPI mode or XIP mode, tD will be longer (80ns or 100ns)
due to internal cycle time unless read operation is terminated by driving CS high in the specific address. In
case the read operation is terminated either in A1=1 and other address = “don’t care” during QPI mode or
in A1=1, A0=1 and other address = “don’t care” during XIP mode, tD=40ns can be kept.
*2 : Use “AC Load Equivalent Circuit 2” for these condition or parameters. Others are tested under “AC Load
Equivalent Circuit 1”.
*3 : For the frequency of FRQO and FRQAD commands, the number of dummy cycles is default value of 6.
