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
  • Padauk PDK14 and PDK15[4]
  • Sharp SM83, the CPU found in the Nintendo Game Boy LR35902 SoC
  • STMicroelectronics STM8
  • Zilog Z80, Z180, eZ80 in Z80 mode; Rabbit Semiconductor 2000, 2000A, 3000, 3000A, 4000; Toshiba TLCS-90; Z80N (ZX Spectrum Next processor), R800.
  • MOS Technology 6502, WDC 65C02.

Work in progress:

  • Microchip PIC16 and PIC18.[5]
  • Padauk PDK13.

Obsolete:

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