3.5.1

General purpose I/O (GPIO) DC parameters

Table 26 shows DC parameters for GPIO pads. The parameters in Table 26 are guaranteed per the

operating ranges in Table 7, unless otherwise noted.

3.5.2

DDR I/O DC electrical characteristics

The DDR I/O pads support LPDDR 4, DDR4, and DDR3L operational modes. The DDR Memory

Controller (DDRMC) is designed to be compatible with JEDEC-compliant SDRAMs.
