Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 21 and

Table 54, respectively.

Unless otherwise specified, the parameters given are derived from tests performed under

ambient temperature and VDD supply voltage conditions summarized in Table 22.

1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the RM0313 reference manual for a description of

GPIO Port configuration register.

2. The maximum frequency is defined in Figure 21.

3. Guaranteed by design, not tested in production.

4. The I/O speed configuration is bypassed in FM+ I/O mode. Refer to the STM32F37xx and STM32F38xx reference manual

RM0313 for a description of FM+ I/O mode configuration
