The Small Device C Compiler (SDCC) is a free-software, partially retargetable[1] C compiler for microcontrollers. It is distributed under the GNU General Public License. The package also contains a linker, assembler, simulator and debugger. As of March 2007, SDCC is the only open-source C compiler for Intel 8051-compatible microcontrollers.[2][3][4][citation needed] In 2011 the compiler was downloaded on average more than 200 times per day.[5]

The SDCC compiler was used by the FreeRTOS project to port its real-time operating system to the 8051-based Silabs (formerly Cygnal) series of microcontrollers.
