Frequently asked questions
The STM8S and STM8A microcontrollers can be supplied through an external source with a voltage range of 3.0 V to 5.5 V.
The SWIM interface is a single-wire hardware interface used for in-circuit debugging and programming of STM8S and STM8A devices. It allows non-intrusive access to RAM and peripherals, offering a powerful and efficient debug solution.
The STM8 software toolchain includes the ST visual develop (STVD) integrated development environment, a C compiler (Cosmic or Raisonance), and an optional firmware library. STVD provides an easy-to-use environment for building, debugging, and programming STM8S and STM8A applications.
The STice is a modular, high-end emulator system that connects to the PC via USB and to the application board in place of the target microcontroller, enabling advanced debugging and programming capabilities.
The RLink is a low-cost in-circuit debugger/programmer that communicates with the on-board debug module of the STM8 through the SWIM interface. It allows for debugging and programming STM8S and STM8A devices.
