PRODUCTION DATA
The device contains six multimaster Inter-Integrated Circuit (I2C) controllers each of which provides an interface between a local host (LH), such as an Arm and any I2C-bus-compatible device that connects via the I2C serial bus. External components attached to the I2C bus can serially transmit and receive up to 8 bits of data to and from the LH device through the 2-wire I2C interface.
Each multimaster I2C module can be configured to act like a slave or master I2C-compatible device.
The WKUP_I2C0 and MCU_I2C0 controllers have dedicated I2C compliant open drain buffers, and support fast mode (up to 400 Kbps).The I2C0, I2C1, I2C2, and I2C3 controllers are multiplexed with standard LVCMOS I/O and connected to emulate open drain.The I2C emulation is achieved by configuring the LVCMOS buffers to output Hi-Z instead of driving high when transmitting logic 1.
