Universal synchronous/asynchronous receiver/transmitter

(USART)

The device embeds up to two universal synchronous/asynchronous receivers/transmitters

(USART1, USART2) which communicate at speeds of up to 6 Mbit/s.

They provide hardware management of the CTS, RTS and RS485 DE signals,

multiprocessor communication mode, master synchronous communication and single-wire

half-duplex communication mode. USART1 supports also SmartCard communication (ISO

7816), IrDA SIR ENDEC, LIN Master/Slave capability and auto baud rate feature, and has a

clock domain independent of the CPU clock, allowing to wake up the MCU from Stop mode.

The USART interfaces can be served by the DMA controller.
