Electrical characteristics
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 19 and
Table 45, respectively.
Unless otherwise specified, the parameters given in Table 45 are derived from tests
performed under the 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.
3. The maximum frequency is defined in Figure 19.
