99 / 135 page  DocID025644 Rev 3 99/135 STM32F401xD STM32F401xE Electrical characteristics 114 Figure 33. I2C bus AC waveforms and measurement circuit 1. RS = series protection resistor. 2. RP = external pull-up resistor. 3. VDD_I2C is the I2C bus power supply. Table 60. SCL frequency (fPCLK1= 42 MHz, VDD = VDD_I2C = 3.3 V)(1)(2) 1. RP = External pull-up resistance, fSCL = I2C speed 2. For speeds around 200 kHz, the tolerance on the achieved speed is of ±5%. For other speed ranges, the tolerance on the achieved speed is ±2%. These variations depend on the accuracy of the external components used to design the application. fSCL (kHz) I2C_CCR value RP = 4.7 kΩ 400 0x8019 300 0x8021 200 0x8032 100 0x0096 50 0x012C 20 0x02EE |
