EBI Timings
Power-Up Sequence
Figure 39-3.
VDDCORE and VDDBU are controlled by internal POR (Power-On-Reset) to guarantee that
these power sources reach their target values prior to the release of POR.
As T
These timings are given for worst case Process, T° = 85°C and VDDCORE = Min.
First column for VDDIOM in 1.8V Supply range (1.65V-1.95V) and 30 pF load capacitance.
Second column for VDDIOM in 3.3V Supply range (3.0V-3.6V) and 50 pF load capacitance.
