Electrical characteristics
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 27 and
Table 45, respectively.
Unless otherwise specified, the parameters given in Table 45 are derived from tests
performed under the ambient temperature and V_DD supply voltage conditions summarized
in Table 9.

1. The I/O speed is configured using the MODEx[1:0] bits. Refer to the STM32F100xx reference manual for a
description of GPIO Port configuration register.
2. The maximum frequency is defined in Figure 27.
3. Guaranteed by design, not tested in production.
