Notes:
1. Please note that 3.3 V LVCMOS wide range is applicable to 100 A drive strength only. The configuration
will NOT operate at the equivalent software default drive strength. These values are for normal ranges
ONLY.
2. Software default selection highlighted in gray.
3. For specific junction temperature and voltage supply levels, refer to Table 2-6 on page 2-6 for derating values.
