Doc ID 13587 Rev 14
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 30 and
Table 37, respectively.
Unless otherwise specified, the parameters given in Table 37 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 9.
Table 37.
I/O AC characteristics(1)
1.
The I/O speed is configured using the MODEx[1:0] bits. Refer to the STM32F10xxx reference manual for a
description of GPIO Port configuration register.
