I have been trying to read about I2C pullups such that I can select an appropriate pullup resistor for an EEPROM (24LC02B-I/P) which I want to use as serial ROM to drive some 7-segment displays.
Despite the advice in this 'AddOhms' video I still am curious about how you actually calculate a pullup and a caulcated pullup range, but this TI document baffles me totally in section 2. Below are some specific questions:
Why does Rp(min) take an output low voltage from Vcc?
It talks of bus capacitance: the only reference I can find on the datasheet of the EEPROM is to pin capacitance (10 picofarads)- is this one and the same?
Sorry if these questions seem diverse and broad, I am just struggling with the concept generally and getting a bit frustrated with it
