The Small Device C Compiler (SDCC) is a free-software, partially retargetable[1] C compiler for 8-bit microcontrollers. It is distributed under the GNU General Public License. The package also contains an assembler, linker, simulator and debugger. SDCC is a popular open-source C compiler for microcontrollers compatible with Intel 8051/MCS-51.[2][3][4]

Supported hosts

[edit]

Sources, documentation, and binaries are available for Linux (32-bit and 64-bit), macOS (PPC and 64-bit), and Windows (32-bit and 64-bit).

Supported targets

[edit]

The following include binary compatible derivatives:

Work in progress:

Obsolete:

  • AVR microcontrollers used to be a supported target, but was made obsolete by avr-gcc in 2010 (SDCC 3.0.0).
