Electrical characteristics

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.
