Electrical characteristics
195
The 20mA output drive requirement in Fast-mode Plus is not supported. This limits the
maximum load Cload supported in Fm+, which is given by these formulas:
•
Tr(SDA/SCL)=0.8473xRpxCload
•
Rp(min)= (VDD-VOL(max))/IOL(max)
Where Rp is the I2C lines pull-up. Refer to
Section 5.3.17: I/O port characteristics for the
I2C I/Os characteristics.
All I2C SDA and SCL I/Os embed an analog filter. Refer to the table below for the analog
filter characteristics:
Table 75. I2C analog filter characteristics(1)
