Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 19 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 13.

1. The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the STM32L151x6/8/B and STM32L152x6/8/B
reference manual for a description of GPIO Port configuration register.
2. Guaranteed by design.
3. The maximum frequency is defined in Figure 19.
