87 / 121 page  DocID025660 Rev 6 87/121 STM32L063x8 Electrical characteristics 107 Input/output AC characteristics The definition and values of input/output AC characteristics are given in Figure 23 and Table 60, respectively. Unless otherwise specified, the parameters given in Table 60 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 24. Table 60.

The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the line reference manual for a description of GPIO Port configuration register. 2. Guaranteed by design. 3. The maximum frequency is defined in Figure 23. 4. When Fm+ configuration is set, the I/O speed control is bypassed. Refer to the line reference manual for a detailed description of Fm+ I/O configuration. |
