Pinouts and pin description
Table 5.
1. I = input, O = output, S = supply, HiZ = high impedance.
2. FT = 5 V tolerant. All I/Os are V
3. Function availability depends on the chosen device.
4. If several peripherals share the same I/O pin, to avoid conflict between these alternate functions only one peripheral should
5. PC13, PC14 and PC15 are supplied through the power switch, and so their use in output mode is limited: they can be used
6. Main function after the first backup domain power-up. Later on, it depends on the contents of the Backup registers even
7. This alternate function can be remapped by software to some other port pins (if available on the used package). For more
8. SPI2/I2S2 and I2C2 are not available when the Ethernet is being used.
9. For the LQFP64 package, the pins number 5 and 6 are configured as OSC_IN/OSC_OUT after reset, however the

after reset (because these registers are not reset by the main reset). For details on how to manage these IOs, refer to the
Battery backup domain and BKP register description sections in the STM32F10xxx reference manual, available from the
STMicroelectronics website: www.st.com.

functionality of PD0 and PD1 can be remapped by software on these pins. For the LQFP100 and BGA100 packages, PD0
and PD1 are available by default, so there is no need for remapping. For more details, refer to Alternate function I/O and
debug configuration section in the STM32F10xxx reference manual.
