STM32F103x8, STM32F103xB
Pinouts and pin description
8. This alternate function can be remapped by software to some other port pins (if available on the used package). For more
details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual, available
from the STMicroelectronics website: www.st.com.
9. The pins number 2 and 3 in the VFQFPN36 package, 5 and 6 in the LQFP48 and LQFP64 packages, and C1 and C2 in the
TFBGA64 package are configured as OSC_IN/OSC_OUT after reset, however the functionality of PD0 and PD1 can be
remapped by software on these pins. For the LQFP100 package, PD0 and PD1 are available by default, so there is no need
for remapping. For more details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx
reference manual.
The use of PD0 and PD1 in output mode is limited as they can only be used at 50 MHz in output mode.
