Electrical characteristics

Figure 4. I/O output DC electrical characteristics definition

The following tables provide DC characteristics for bidirectional pads:

•

Table 13 provides output driver characteristics for I/O pads when in WEAK/SLOW

configuration.

•

Table 14 provides output driver characteristics for I/O pads when in MEDIUM

configuration.

•

Table 15 provides output driver characteristics for I/O pads when in STRONG/FAST

configuration.

•

Table 16 provides output driver characteristics for I/O pads when in VERY

STRONG/VERY FAST configuration.

Note:

10%/90% is the default condition for any parameter if not explicitly mentioned differently.
