COSMIC STM8 16K C Compiler 4.3

Developed by COSMIC Software, the COSMIC STM8 16K C Compiler is a professional C toolchain tailored for STMicroelectronics’ STM8 8-bit microcontrollers. It delivers highly optimized, reliable, and deterministic code generation designed to make the most of the STM8 architecture. The 16K edition targets applications up to 16 KB of program memory, making it well suited for compact, cost-sensitive designs and evaluation.

The toolchain includes a C compiler, assembler, linker, librarian, and supporting utilities, along with device-specific header files, startup code, and runtime libraries. It supports interrupt-driven development, inline assembly, mixed C/assembly projects, and multiple memory models to balance speed and size. Detailed diagnostics, map and listing outputs, and optimization options help you fine-tune performance and minimize code size. The compiler works smoothly with ST’s development environments and common debugging tools, and it supports command-line usage for automated builds.

Backed by COSMIC Software’s long-standing focus on embedded systems, the STM8 16K C Compiler offers a dependable path from prototype to production on the STM8 platform.
