74 / 94 page  Electrical characteristics STM32G030x6/x8 74/94 DS12991 Rev 1 All I2C SDA and SCL I/Os embed an analog filter. Refer to the following table for its characteristics: SPI/I2S characteristics Unless otherwise specified, the parameters given in Table 64 for SPI are derived from tests performed under the ambient temperature, fPCLKx frequency and supply voltage conditions summarized in Table 21: General operating conditions. The additional general conditions are: • OSPEEDRy[1:0] set to 11 (output speed) • capacitive load C = 30 pF • measurement points at CMOS levels: 0.5 x VDD Refer to Section 5.3.14: I/O port characteristics for more details on the input/output alternate function characteristics (NSS, SCK, MOSI, MISO for SPI). Table 63. I2C analog filter characteristics(1) 1. Based on characterization results, not tested in production.
