Product details
Overview
RTCRL7800CB01WNRNT from Renesas Electronics is a C++14 language compiler option package for the RL78 family of 8-bit 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 RTCRL7800CB01WNRNT datasheet, RTCRL7800CB01WNRNT pinout, RTCRL7800CB01WNRNT application, or RTCRL7800CB01WNRNT equivalent, this product enables C++14-based firmware development targeting RL78 MCUs while maintaining strict compliance with memory model constraints, interrupt handling requirements, and startup initialization sequences defined in CC-RL V1.14.00.
Technical Context
The RTCRL7800CB01WNRNT implements a freestanding C++14 environment for RL78 microcontrollers, with no support for exception handling, RTTI, threads, or atomic operations. It defines char as unsigned by default (switchable via -signed_char), enforces 8-bit bytes, and uses near/far pointer models aligned to 2-byte boundaries.
It supports C++14 core language features including constexpr, auto type deduction, range-based for loops, and uniform initialization, while restricting MISRA checks, stack protection, and intermodule optimization - all validated against RL78-specific startup routines and memory layout constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Language Standard | ISO/IEC 14882:2014 (C++14), confirmed for RL78 family toolchain integration |
| Integer Sizes | int and short are 2-byte signed types; long is 4-byte signed - matches RL78's 16-bit ALU and memory addressing |
| Floating Point | float and double (-double_size=4) are 4-byte IEEE 754 types - optimized for RL78's hardware-assisted FP unit |
| Character Encoding | UTF-8 source file encoding enforced; no -character_set option effect - ensures consistent multilingual string handling |
| Startup Model | Freestanding environment with C-linkage main; global object initialization handled by RL78-specific startup routine |
| Pointer Model | Near pointers (2-byte) for RAM/ROM access; far pointers (4-byte) for extended memory - aligns with RL78's segmented memory map |

FAQ
What is RTCRL7800CB01WNRNT and how does it differ from standard C compilers?
RTCRL7800CB01WNRNT is a Renesas-provided C++14 language extension for the CC-RL compiler targeting RL78 MCUs. Unlike standard C compilers, RTCRL7800CB01WNRNT enables ISO/IEC 14882:2014 syntax and semantics - including constexpr, auto, and uniform initialization - while preserving RL78-specific memory models, startup behavior, and interrupt handling. It requires explicit -lang=cpp14 invocation and rejects C source files.
Does RTCRL7800CB01WNRNT support exceptions or RTTI?
No. RTCRL7800CB01WNRNT explicitly omits support for exception handling, runtime type identification (RTTI), threads, and atomic operations per its documented limitations. These omissions ensure deterministic code size and timing - critical for RL78-based safety-critical and resource-constrained applications where RTCRL7800CB01WNRNT is deployed.
What data type sizes does RTCRL7800CB01WNRNT enforce for RL78 targets?
RTCRL7800CB01WNRNT enforces int and short as 2-byte signed types, long as 4-byte signed, and char as 1-byte unsigned (configurable to signed via -signed_char). These mappings directly reflect RL78's 16-bit architecture and memory addressing capabilities - ensuring predictable stack usage, register allocation, and peripheral register interaction in RTCRL7800CB01WNRNT-compiled firmware.
Can RTCRL7800CB01WNRNT be used with MISRA-C or MISRA-C++ compliance workflows?
No. RTCRL7800CB01WNRNT does not support MISRA-C or MISRA-C++ checking options (-misra2004, -misra2012); these flags are explicitly marked non-combinable in its option matrix. Compliance workflows must rely on external static analyzers or post-compilation verification tools - RTCRL7800CB01WNRNT itself provides no built-in MISRA enforcement.
Is RTCRL7800CB01WNRNT compatible with RL78 G13 or G14 microcontroller families?
Yes. RTCRL7800CB01WNRNT is part of the CC-RL V1.14.00 toolchain, which supports all RL78 family devices including G13, G14, and legacy variants. Its -cpu option selects target silicon, and all generated code adheres to RL78 instruction set architecture and memory map constraints - verified across RL78 device groups in Renesas' official release notes.
