(10) I/O Expanded Serial Interface Timing
(VCC
= 2.7 V to 3.6 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
Notes :
These AC ratings are for operation in CLK synchronous mode.
CL is the load capacitance applied to pins during testing.
tCP : See (1) Clock Timing Ratings.
Values shown are target values.
VCC = VCC3 = VCC5
