Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 25 and
Table 52, respectively.
Unless otherwise specified, the parameters given in Table 52 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 STM32L151xx, STM32L152xx and STM32L162xx
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 25.
