16 GPIO

This section describes the DC and AC electrical specifications for the GPIO.

16.1

GPIO DC Electrical Characteristics

Table 56 provides the DC electrical characteristics for the GPIO when the GPIO pins are operating from

a 3.3-V supply.

Table 57 provides the DC electrical characteristics for the GPIO when the GPIO pins are operating from

a 2.5-V supply.

Table 56. GPIO (When Operating at 3.3 V) DC Electrical Characteristics1

1 This specification only applies to GPIO pins that are operating from a 3.3-V supply. See Table 63 for the power supply listed

for the individual GPIO signal.
