Because 5V inputs cannot be accepted using the 3.3V sys-
tem interface, all input signals must be driven at 3.3V logic
levels.
With the 5V system interface, outputs are driven with 5V
logic levels. The input is dened by 3.3V logic levels, but
inputs greater than 3.3V can also be tolerated. The CPU
and core logic power supply current is the same for both
3.3V and 5V operation.
In the 5V system interface, two power supplies are
required. While there are basically no restrictions on
power supply sequencing, the following sequence is recom-
mended:
At power-on
VDD
IO_VDD

5V Interface IO_VDD = 5V ± 5%
VDD = 3.3V ± 0.3V, VSS = 0V, Ta = 0~70°C
3.3V Interface
IO_VDD = VDD = 3.3V ± 0.3V, VSS = 0V, Ta = 0~70
