3.5 I/O DC parameters
This section includes the DC parameters of the following I/O types:
• General Purpose I/O (GPIO)
• Double Data Rate I/O (DDR) for LPDDR4, DDR4, and DDR3L modes
• Differential I/O (CLKx)
3.5.1 General purpose I/O (GPIO) DC parameters
Table 25 shows DC parameters for GPIO pads. The parameters in Table 25 are guaranteed per the
operating ranges in Table 7, unless otherwise noted.
