61 / 74 page  STR71xF Electrical parameters 61/74 period of SCL signal. 4. Measurement points are done at CMOS levels: 0.3xVDD and 0.7xVDD. 5. fPCLK1, must be at least 8MHz to achieve max fast I 2C speed (400kHz). 6. The following table gives the values to be written in the I2CCCR register to obtain the required I2C SCL line frequency. Figure 33. Typical Application with I 2C Bus and Timing Diagram 4) Legend: RP = External pull-up resistance fSCL = I 2C speed NA = Not achievable Note: For speeds around 200 kHz, achieved speed can have ±5% tolerance For other speed ranges, achieved speed can have ±2% tolerance The above variations depend on the accuracy of the external components used. USB Characteristics The USB interface is USB-IF certified (Low Speed and Full Speed). Table 35.
