1. The DC/AC Test Output Load of K4S643232C-55/60/70 is 30pF.
2. The VDD condition of K4S643232C-55/60 is 3.135V~3.6V.
Note :
OPERATING AC PARAMETER
1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then
rounding off to the next higher integer. Refer to the following ns-unit based AC table.
