tolerant.3.Function availability depends on the chosen device. For devices having reduced peripheral counts, it is always the lowernumber of peripheral that is included. For example, if a device has only one SPI and two USARTs, they will be called SPI1 and USART1 & USART2, respectively. Refer to Table 2 on page 10.4.If several peripherals share the same I/O pin, to avoid conflict between these alternate functions only one peripheral shouldbe enabled at a time through the peripheral clock enable bit (in the corresponding RCC peripheral clock enable register).5.PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current(3mA), the use of GPIOs PC13 to PC15 in output mode is limited: the speed should not exceed 2 MHz with a maximum load of 30 pF and these IOs must not be used as a current source (e.g. to drive an LED).6.Main function after the first backup domain power-up. Later on, it depends on the contents of the Backup registers evenafter 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: .7.Unlike in the LQFP64 package, there is no PC3 in the TFBGA64 package. The V REF+ functionality is provided instead.8.This alternate function can be remapped by software to some other port pins (if available on the used package). For moredetails, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual, available from the STMicroelectronics website: .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 theTFBGA64 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.Table 5.Medium-density STM32F103xx pin definitions (continued)PinsPin nameT y p e (1)I / O L e v e l (2)Main function (3) (after reset)Alternate functions (4)L F B G A 100L Q F P 48/V F Q F P N 48T F B G A 64L Q F P 64L Q F P 100V F Q F P N 36Default Remap。
