GPIO DC Electrical Characteristics

Table 53 provides the DC electrical characteristics for the GPIO when the GPIO pins are operating from

a 3.3-V supply.

Table 54 provides the DC electrical characteristics for the GPIO when the GPIO pins are operating from

a 2.5-V supply.

Table 53. GPIO (When Operating at 3.3V ) DC Electrical Characteristics 1

This specification only applies to GPIO pins that are operating from a 3.3-V supply. See Table 60 for the power

supply listed for the individual GPIO signal.
