Serial interfaces

Functional description

The STM32W108 has two serial controllers, SC1 and SC2, which provide several options

for full-duplex synchronous and asynchronous serial communications.

●

SPI (Serial Peripheral Interface), master or slave

●

I2C (Inter-Integrated Circuit), master only

●

UART (Universal Asynchronous Receiver/Transmitter), SC1 only

●

Receive and transmit FIFOs and DMA channels, SPI and UART modes

Receive and transmit FIFOs allow faster data speeds using byte-at-a-time interrupts. For the

highest SPI and UART speeds, dedicated receive and transmit DMA channels reduce CPU

loading and extend the allowable time to service a serial controller interrupt. Polled

operation is also possible using direct access to the serial data registers. Figure 10 shows

the components of the serial controllers.

Note:

The notation SCx means that either SC1 or SC2 may be substituted to form the name of a

specific register or field within a register.
