1. I = input, O = output, S = supply.
2. FT = 5 V tolerant.
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 be 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 (3 mA), 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 even 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.
7. Unlike in the LQFP64 package, there is no PC3 in the WLCSP 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 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. For the LQFP64 package, the pins number 5 and 6 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/BGA100 and LQFP144/BGA144 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.
10. For devices delivered in LQFP64 packages, the FSMC function is not available.

The definition and values of input/output AC characteristics are given in Figure 41 and Table 47 , respectively.

Unless otherwise specified, the parameters given in Table 47 are derived from tests performed under ambient temperature and V DD supply voltage conditions summarized in Table 10 .

Stresses above the absolute maximum ratings listed in Table 7: Voltage characteristics , Table 8: Current characteristics , and Table 9: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

Symbol	Ratings	Min	Max	Unit
V DD -V SS	External main supply voltage (including V DDA and V DD ) (1)	-0.3	4.0	V
V IN	Input voltage on five volt tolerant pin (2)	V SS 0.3	+5.5	V
V IN	Input voltage on any other pin (2)	V SS 0.3	V DD +0.3	V
| V DDx |	Variations between different V DD power pins		50	mV
|V SSX V SS |	Variations between all the different ground pins		50	mV
V ESD(HBM)	Electrostatic discharge voltage (human body model)	see Section 5.3.12: Absolute maximum ratings (electrical sensitivity)	see Section 5.3.12: Absolute maximum ratings (electrical sensitivity)

Symbol	Ratings	Max.	Unit
I VDD	Total current into V DD /V DDA power lines (source) (1)	150	mA
I VSS	Total current out of V SS ground lines (sink) (1)	150	mA
I IO	Output current sunk by any I/O and control pin	25	mA
I IO	Output current source by any I/Os and control pin	25	mA
I INJ(PIN) (2)(3)	Injected current on NRST pin	± 5	mA
I INJ(PIN) (2)(3)	Injected current on HSE OSC_IN and LSE OSC_IN pins	± 5	mA
I INJ(PIN) (2)(3)	Injected current on any other pin (4)	± 5	mA
I INJ(PIN) (2)	Total injected current (sum of all I/O and control pins) (4)	± 25	mA

1. Negative injection disturbs the analog performance of the device. See note in Section 5.3.18: 12-bit ADC characteristics .
2. When several inputs are submitted to a current injection, the maximum I INJ(PIN) is the absolute sum of the positive and negative injected currents (instantaneous values). These results are based on characterization with I INJ(PIN) maximum current injection on four I/O port pins of the device.

Table 9. Thermal characteristics

Symbol	Ratings	Value	Unit
T STG	Storage temperature range	-65 to +150	°C
T J	Maximum junction temperature	150	°C

The maximum chip junction temperature (T J max) must never exceed the values given in Table 10: General operating conditions on page 42 .

The maximum chip-junction temperature, T J max, in degrees Celsius, may be calculated using the following equation:

$$T_J,\text{max} = T_A,\text{max} + (P_D,\text{max} \times \Theta_{JA})$$
