Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 18 and
Table 44, respectively.
Unless otherwise specified, the parameters given in Table 44 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 14.

1.
The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the STM32L15xxx 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 18.
