Product details
Overview
RTCRL7800CL01WNRL5 from Renesas Electronics is a C++14 language compiler option package for the RL78 family microcontrollers, supporting ISO/IEC 14882:2014 standard compilation with -lang=cpp14 flag, 2-byte int and long data types, UTF-8 source encoding, and IEEE 754-compliant float/double arithmetic - used in embedded firmware development for industrial control and sensor nodes.
For engineers reviewing the RTCRL7800CL01WNRL5 datasheet, RTCRL7800CL01WNRL5 pinout, RTCRL7800CL01WNRL5 application, or RTCRL7800CL01WNRL5 equivalent, this is a software tool-not a physical component-and requires CC-RL V1.14.00 compiler suite, RL78 target device support, and compliance with Renesas' freestanding C++ implementation constraints including no exception handling, no RTTI, and no threading.
Technical Context
The RTCRL7800CL01WNRL5 defines a C++14 compilation mode within the CC-RL toolchain, enforcing strict freestanding environment behavior: main() linkage is C-style, dynamic initialization of static objects depends on startup routine, and wchar_t/char16_t are 2-byte unsigned types. It disables MISRA checks, -volatile, -stack_protector, and multi-file optimization options like -Omerge_files.
This option mandates UTF-8 source interpretation, implements arithmetic right-shift for negative values, treats unspecified bitfields as signed (unlike C mode), and supports intrinsic functions and #pragma directives only as defined in CC-RL's C++14 subset - excluding __saddr, __callt, and __sectop reserved words.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Compiler Mode | C++14 standard (ISO/IEC 14882:2014) with freestanding implementation |
| Integer Sizes | int and short are 2-byte; long is 4-byte; long long is 8-byte - impacts memory layout and register allocation |
| Floating Point | float and double (-double_size=4) are IEEE 754 32-bit; double (-double_size=8) is 64-bit - determines precision and range in math operations |
| Character Encoding | Source files must be UTF-8; execution character set matches source - eliminates encoding ambiguity in literals and identifiers |
| Thread Support | No threads, no atomic operations, no std::thread or |
| Exception Handling | Not supported; no try/catch, no noexcept, no stack unwinding - eliminates runtime overhead and binary size bloat |
| Startup Behavior | Global object initialization order depends on CC-RL startup routine; main() has C linkage and no parameters - constrains initialization sequencing in complex firmware |

FAQ
Is RTCRL7800CL01WNRL5 a physical IC or a software license?
RTCRL7800CL01WNRL5 is a software compiler option - not a physical integrated circuit or hardware component. It is a licensable feature enabling C++14 language support within the Renesas CC-RL V1.14.00 compiler suite for RL78 microcontrollers. No PCB footprint, pinout, or electrical characteristics apply.
Does RTCRL7800CL01WNRL5 support exception handling or RTTI?
No. RTCRL7800CL01WNRL5 explicitly excludes exception handling, runtime type identification (RTTI), threads, and atomic operations per its documented C++14 freestanding implementation. These omissions reduce code size and eliminate non-deterministic runtime behavior - critical for safety-aware RL78 deployments.
What RL78 device families are compatible with RTCRL7800CL01WNRL5?
RTCRL7800CL01WNRL5 is compatible with all RL78 family microcontrollers supported by CC-RL V1.14.00, including RL78/G10, G12, G13, G14, G1A, G23, and L12. Device-specific startup code, peripheral register definitions, and linker scripts must match the target MCU variant.
Can RTCRL7800CL01WNRL5 be used with C source files?
No. RTCRL7800CL01WNRL5 requires C++ source files (.cpp). A compile error occurs if C source files (.c) are passed to the compiler with the -lang=cpp14 option. Mixed-language projects must separate C and C++ compilation units and link object files externally.
How does RTCRL7800CL01WNRL5 handle signed vs. unsigned char by default?
By default, RTCRL7800CL01WNRL5 treats char as unsigned (0 to +255). This differs from many desktop C++ implementations and can affect portability of bitwise logic and character comparisons. The -signed_char compiler option overrides this to make char signed (-128 to +127).
