1. All VDD_HV_IO conditions for 4.5V to 5.5V are valid for VSIO[VSIO_xx] = 1, and all specifications for 3.0V to 3.6V are valid

for VSIO[VSIO_xx] = 0

2. All values need to be confirmed during device validation.

3. CL is the sum of external capacitance. Device and package capacitances (CIN, defined in Table 12) are to be added to

calculate total signal capacitance (CTOT = CL + CIN).

4. Transition time maximum value is approximated by the following formula:

0 pF < CL < 50 pFtTR_W(ns) = 22 ns + CL(pF)

× 4.4 ns/pF

50 pF < CL < 200 pFtTR_W(ns) = 50 ns + CL(pF)

× 3.85 ns/pF

5. Only for VDD_HV_IO_JTAG segment when VSIO[VSIO_IJ] = 0 or VDD_HV_IO_ETH segment when VSIO[VSIO_IF] = 0.
