Electrical characteristics
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 21 and
Table 46, respectively. Unless otherwise specified, the parameters given are derived from
tests performed under the ambient temperature and supply voltage conditions summarized
in Table 18: General operating conditions.

1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the STM32F0xxxx RM0091 reference
manual for a description of GPIO Port configuration register.
2. Guaranteed by design, not tested in production.
3. The maximum frequency is defined in Figure 21.
4. When Fm+ configuration is set, the I/O speed control is bypassed. Refer to the STM32F0xxxx reference
manual RM0091 for a detailed description of Fm+ I/O configuration.
