76 / 106 page  Electrical characteristics STM32L100RC 76/106 DocID024995 Rev 5 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. Table 43. I/O AC characteristics(1) OSPEEDRx [1:0] bit value(1) Symbol Parameter Conditions Min Max(2) Unit 00 fmax(IO)out Maximum frequency(3) CL = 50 pF, VDD = 2.7 V to 3.6 V - 400 kHz CL = 50 pF, VDD = 1.65 V to 2.7 V - 400 tf(IO)out tr(IO)out Output rise and fall time CL = 50 pF, VDD = 2.7 V to 3.6 V - 625 ns CL = 50 pF, VDD = 1.65 V to 2.7 V - 625 01 fmax(IO)out Maximum frequency(3) CL = 50 pF, VDD = 2.7 V to 3.6 V - 2 MHz CL = 50 pF, VDD = 1.65 V to 2.7 V - 1 tf(IO)out tr(IO)out Output rise and fall time CL = 50 pF, VDD = 2.7 V to 3.6 V - 125 ns CL = 50 pF, VDD = 1.65 V to 2.7 V - 250 10 Fmax(IO)out Maximum frequency(3) CL = 50 pF, VDD = 2.7 V to 3.6 V - 10 MHz CL = 50 pF, VDD = 1.65 V to 2.7 V - 2 tf(IO)out tr(IO)out Output rise and fall time CL = 50 pF, VDD = 2.7 V to 3.6 V - 25 ns CL = 50 pF, VDD = 1.65 V to 2.7 V - 125 11 Fmax(IO)out Maximum frequency(3) CL = 30 pF, VDD = 2.7 V to 3.6 V - 50 MHz CL = 50 pF, VDD = 1.65 V to 2.7 V - 8 tf(IO)out tr(IO)out Output rise and fall time CL = 30 pF, VDD = 2.7 V to 3.6 V - 5 ns CL = 50 pF, VDD = 1.65 V to 2.7 V - 30 -tEXTIpw Pulse width of external signals detected by the EXTI controller -8 - 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. |
