Considerations when using internal pull-up/down resistors

Pull-up resistor clarification

What small IC could give switchable I2C pullups?

When to use pull-down vs. pull-up resistors

What happens if I omit the pullup resistors on I2C lines?

Is it common for internal pull-up resistors to fail? or what would cause them to become intermittent?

Pull-up and Pull-down Resistor Usage on Input or Output MCU Pins

How do I calculate the required value for a pull-up resistor?

Recommendation for default settings for unused pins on an STM32 (ARM Cortex M3) - pull up/pull down?
