4.6.5. I2C

I2C supports communication between integrated circuits on a board. It is a simple two-wire bus that consists of a serial data line (SDA) and a serial clock (SCL). The MAX® 10 and the Stratix® 10 devices use the I2C for reading and writing to the various components on the board such as programmable clock generators, VID regulators, ADC and temperature sensors. You can use the Stratix® 10 or MAX® 10 as the I2C host to access these devices, change clock frequencies or get status information of the board such as voltage and temperature readings.
