Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 44 and
Table 51, respectively.
Unless otherwise specified, the parameters given in Table 51 are derived from tests
performed under ambient temperature and V_DD supply voltage conditions summarized in
Table 10.

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.
2. The maximum frequency is defined in Figure 44.
3. Guaranteed by design, not tested in production.
