Inter-integrated circuit interface (I²C)
The devices feature up to three I²C bus interfaces which can operate in multimaster and
slave modes:
• One I²C interface supports the Standard mode (up to 100 kHz), Fast-mode (up to
400 kHz) modes and Fast-mode plus (up to 1 MHz).
• Two I²C interfaces support the Standard mode (up to 100 KHz) and the Fast mode (up
to 400 KHz). Their frequency can be increased up to 1 MHz. For more details on the
complete solution, refer to the nearest STMicroelectronics sales office.
All I²C interfaces features 7/10-bit addressing mode and 7-bit addressing mode (as slave)
and embed a hardware CRC generation/verification.
They can be served by DMA and they support SMBus 2.0/PMBus.
The devices also include programmable analog and digital noise filters (see Table 6).

Universal synchronous/asynchronous receiver transmitters
(USART)
The devices embed three universal synchronous/asynchronous receiver transmitters
(USART1, USART2 and USART6).
These three interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 12.5 Mbit/s. The USART2 interface communicates at up to
6.25 bit/s.
USART1 and USART2 also provide hardware management of the CTS and RTS signals,
Smart Card mode (ISO 7816 compliant) and SPI-like communication capability. All
interfaces can be served by the DMA controller.
