Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 14 and

Table 43, respectively.

Unless otherwise specified, the parameters given in Table 43 are derived from tests

performed under the conditions summarized in Table 12.

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 14.
