224 / 247 page  Electrical characteristics ST72344xx, ST2345xx 224/247 Doc ID 12321 Rev 6 13.11 Communication interface characteristics 13.11.1 I2C and I²C3SNS interfaces Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified. Refer to I/O port characteristics for more details on the input/output alternate function characteristics (SDAI and SCLI). The ST7 I2C and I2C3SNS interfaces meet the electrical and timing requirements of the Standard I2C communication protocol. TA = -40°C to 85°C, unless otherwise specified. The following table gives the values to be written in the I2CCCR register to obtain the required I2C SCL line frequency. 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. Table 110. I2C and I²C3SNS interfaces characteristics Symbol Parameter Conditions Min Max Unit fSCL I²C SCL frequency fCPU=4 MHz to 8 MHz (1), VDD= 2.7 V to 5.5 V 1. The I2C and I2C3SNS interfaces will not function below the minimum clock speed of 4 MHz. 400 kHz fSCL3SNS I²C3SNS SCL frequency (2) 2. Not tested in production within the whole operating range. Guaranteed by design/validation test results. 400 kHz Table 111. SCL frequency table (multimaster I2C interface) (1) 1. RP = External pull-up resistance, fSCL = I 2C speed, NA = Not achievable. fSCL I2CCCR value fCPU = 4 MHz. fCPU = 8 MHz.
