Small Device C Compiler

The Small Device C Compiler (SDCC) is an open source, 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]. In 2011 the compiler is downloaded on average more than 200 times per day.^[3]

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.

Supported target architectures

• Intel 8051 and its derivatives.
• Zilog Z80 and binary compatible derivatives such as Z180 and eZ80.
• Freescale (Motorola) HC08

Work is in progress on:

• Microchip PIC16 and PIC18
