High-Performance, Low-Power System on Chip
Note:
1) Total power consumption = IDDCORE x 2.5 V + IDDIO x 3.3 V
2) A typical design will provide 3.3 V to the I/O supply (i.e., VDDIO), 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 A typical at VDD = 3.3 V.
