USART
The USART interface (USART1) allows full duplex, asynchronous communications with
external devices requiring an industry standard NRZ asynchronous serial data format. It
offers a very wide range of baud rates.

USART1 can be served by the DMA1 Controller.
Infrared (IR) interface
The STM8L15x devices contain an infrared interface which can be used with an IR LED for
remote control functions. Two timer output compare channels are used to generate the
infrared remote control signals.
Development support
Development tools
Development tools for the STM8 microcontrollers include:
●
●
●
The STM8 also comes with starter kits, evaluation boards and low-cost in-circuit
debugging/programming tools.
Single wire data interface (SWIM) and debug module
The debug module with its single wire data interface (SWIM) permits non-intrusive real-time
in-circuit debugging and fast memory programming.
The Single wire interface is used for direct access to the debugging module and memory
programming. The interface can be activated in all device operation modes.
The non-intrusive debugging module features a performance close to a full-featured
emulator. Beside memory and peripherals, CPU operation can also be monitored in real-
time by means of shadow registers.
Bootloader
A bootloader is available to reprogram the Flash memory using the USART1 interface.
