Small Device C Compiler

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. As of March 2007, SDCC is the only open-source C compiler for Intel 8051-compatible microcontrollers.^[2][3]Cite error: Closing </ref> missing for <ref> tag

Supported hosts

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

The following include binary compatible derivatives:

• Intel 8031, 8032, 8051, 8052; Maxim/Dallas DS80C390; C8051
• Motorola/Freescale/NXP 68HC08 and S08
