CS+
CS+ is Renesas's integrated development environment for creating software for Renesas microcontrollers. Its installer includes compiler packages for target products, and compatible Renesas emulators can provide debugging functions. CS+ for CC supports RL78, RH850 and RX families; CS+ for CA,CX supports RL78, 78K and V850 families. The GUI can generate C device-driver programs for MCU peripherals, though some MCUs do not support generation. Modified or saved source files build automatically in the background, and action events can display variable values at a specified address. Smart Browser in CS+ for CC presents device information, hardware manuals, sample code and related FAQs. The IDE can interoperate with Smart Configurator for RX, and Renesas offers a co-simulation tool connecting CS+ with MATLAB and Simulink. The IDE is free for development and production, but evaluation compiler packages may impose limits. Current versions are listed for Windows 10 64-bit and Windows 11; 32-bit use requires CS+ IDE V8.06 or earlier. Debugging emulators are sold separately.
Who it is for
CS+ suits developers working with the Renesas MCU families supported by its CC or CA,CX variants. It is intended for Windows users developing and debugging MCU software.
What is good
- Free IDE for development and production.
- Background builds modified or saved source files.
- Supports specified Renesas MCU families.
- Smart Browser includes device information and sample code.
What to know first
- Compatible debugging emulators are sold separately.
- Some MCUs do not support code generation.
- 32-bit use requires CS+ IDE V8.06 or earlier.
- Evaluation compiler packages may impose limits.
Verdict
CS+ offers MCU-focused development tools, background builds and debugging support through compatible emulators. Confirm that your MCU family and Windows environment match the listed support, and account for compiler evaluation limits or separate emulator costs.
