SDCC（Small Device C Compiler）是一款面向多种微控制器平台的开源C编译器套件1。该项目于2026年6月22日发布了4.6.0版本1，并获得NGI0基金和Sovereign Tech基金的资助支持1。
两家基金机构将分别支持不同方向的改进工作1。其中，NGI0 Commons基金将用于增强对Padauk、Rabbit和Toshiba TLCS等微控制器架构的支持1；而Sovereign Tech基金则专注于提升嵌入式固件的安全性以及后量子密码学的支持能力1。
SDCC最初由Sandeep Dutta编写，于1999年12月移至SourceForge平台1。在此次发布之前，项目曾于2025年1月28日发布了4.5.0版本1。
