88 / 120 page ![]() Electrical characteristics STM32F103xF, STM32F103xG 88/120 Doc ID 16554 Rev 3 Input/output AC characteristics The definition and values of input/output AC characteristics are given in Figure 44 and Table 51, respectively. Unless otherwise specified, the parameters given in Table 51 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 10. Table 51. I/O AC characteristics(1) 1. The I/O speed is configured using the MODEx[1:0] bits. Refer to the STM32F10xxx reference manual for a description of GPIO Port configuration register. MODEx[1:0] bit value(1) Symbol Parameter Conditions Min Max Unit 10 fmax(IO)out Maximum frequency (2) 2. The maximum frequency is defined in Figure 44.
