73 / 103 page  DocID024295 Rev 5 73/103 STM32L100C6 STM32L100R8/RB Electrical characteristics 90 Input/output AC characteristics The definition and values of input/output AC characteristics are given in Figure 15 and Table 43, respectively. Unless otherwise specified, the parameters given in Table 43 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 12. Table 43.

The I/O speed is configured using the OSPEEDRx[1:0] bits. Refer to the STM32L100C6 and STM32L100R8/RB reference manual for a description of GPIO Port configuration register. 2. Guaranteed by design. 3. The maximum frequency is defined in Figure 15. |
