67 / 97 page ![]() STM32F050xx Electrical characteristics Doc ID 023683 Rev 1 67/97 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 18 and Figure 19 for standard I/Os, and in Figure 20 and Figure 21 for 5 V tolerant I/Os. The following curves are design simulation results, not tested in production. Figure 18. TC and TTa I/O input characteristics - CMOS port Figure 19.
