STM32G030C8T6 – 48-LQFP Pinout

Notes

• PC13, PC14, PC15: Limited output capability (3 mA max sink current). Must not be used as current sources. Maximum speed 2 MHz with 30 pF load. Supplied through power switch; behavior depends on RTC domain state.
• PA0, PA1, PA2: Bonded with NRST on pin 6. Low level on any of these GPIOs triggers device reset. Keep configured as analog or digital inputs to prevent spurious resets.
• PA9, PA10: Can be remapped to PA11/PA12 positions via SYSCFG_CFGR1 register.
• PA13, PA14: Upon reset, configured as SW debug alternate functions with internal pull-up (PA13) and pull-down (PA14) activated.
• PH0, PH1: Typically used for external oscillator (OSC_IN, OSC_OUT).

The definition and values of input/output AC characteristics are given in Figure 18 and Table 51 , respectively.

Unless otherwise specified, the parameters given are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 21: General operating conditions .

1. Guaranteed by design.
2. This value represents the I/O capability but the maximum system frequency is limited to 64 MHz.
3. The fall time is defined between 70% and 30% of the output waveform, according to I 2 C specification.

1. Refer to Table 51: I/O AC characteristics .

Stresses above the absolute maximum ratings listed in Table 18 , Table 19 and Table 20 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.

All voltages are defined with respect to V SS .

Table 18. Voltage characteristics

Table 19. Current characteristics

Table 20. Thermal characteristics

The operating junction temperature T J must never exceed the maximum given in Table 21: General operating conditions

The maximum junction temperature in °C that the device can reach if respecting the operating conditions, is:T _ { J } ( max ) = T _ { A } ( max ) + P _ { D } ( max ) × Θ _ { J A }
