83 / 128 page ![]() STM32F37x Electrical characteristics Doc ID 022691 Rev 3 83/128 Note: I/O pins are powered from VDD voltage except pins which can be used as SDADC inputs: - PB2, PB10 and PE7 to PE15 I/O pins are powered from VDDSD12. - PB14 to PB15 and PD8 to PD15 I/O pins are powered from VDDSD3. All I/O pin ground is internally connected to VSS. VDD mentioned in the Table 52 represents power voltage for a given I/O pin (VDD or VDDSD12 or VDDSD3). All I/Os are CMOS and TTL compliant (no software configuration required). Their characteristics cover more than the strict CMOS-technology or TTL parameters. The coverage of these requirements is shown in Figure 17 and Figure 18 for standard I/Os, and in Figure 19 and Figure 20 for 5 V tolerant I/Os. Figure 17.
