Electrical characteristics
STM32F103x8, STM32F103xB
62/116
DS5319 Rev 18
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 26 and Figure 27 for standard I/Os, and
in Figure 28 and Figure 29 for 5 V tolerant I/Os.

7. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
PMOS/NMOS contribution to the series resistance is minimum (~10%).
