High-Performance, Low-Power System on Chip
Note:
1) Total power consumption = IDD
CORE
x 2.5 V + IDD
IO
x 3.3 V
2) A typical design will provide 3.3 V to the I/O supply (i.e., V
DDIO
), and 2.5 V to the remaining logic. This is to allow the I/O to be
compatible with 3.3 V powered external logic (i.e., 3.3 V SDRAMs).
2) Pull-up current = 50 μA typical at V
DD
= 3.3 V.
