AI 生成的摘要: The RL78 Family SHA Hash Function Library includes various source files, sample programs, and documentation to support SHA-1 and SHA-256 hash functions. It provides API functions to generate SHA-1 and SHA-256 hash digests, with SHA-256 support enhanced when combined with the RL78/G24 FAA accelerator. The library supports specific compiler environments and requires building designated source files depending on the API used. The FAA accelerator improves SHA processing speed and supports only SHA-256 with certain compilers.

AI 生成的摘要: The 24-bit Az (Delta-Sigma) A/D converter features 24-bit resolution with a minimum SNDR of 80 dB, supporting 3 or 4 differential input channels depending on the product pin count. It includes a programmable gain amplifier with selectable gains, an internal reference voltage generator, and selectable sampling and high-pass filter frequencies. The converter operates with a high-speed system clock or on-chip oscillator, requiring specific initialization and clock stabilization procedures for accurate conversion results.

AI 生成的摘要: The document explains how to integrate and use IAR Systems compilers within the e² studio development environment for Renesas microcontrollers. It details the installation of IAR Embedded Workbench and IAR Eclipse plugins, project creation, build configuration, and build execution using IAR compilers. The guide focuses on the RA family with the IAR ARM compiler but applies similarly to other Renesas devices. It also recommends using standalone Flexible Software Package configurators for RA and RZ families to enhance development. The environment setup assumes Windows 10 64-bit, e² studio 2024-07, and IAR tools installed.

AI 生成的摘要: The document details self test software routines for RL78 microcontrollers to ensure compliance with IEC60730/60335 Class B safety standards. It covers CPU register tests, internal Flash and SRAM memory checks, system clock verification using independent clock sources, and peripheral tests such as A/D converters and watchdog timers. The self test library offers modular APIs for integration into applications, supporting reliability and safety in automatic electronic control systems like household appliances. The document also includes example usage, benchmarking, and additional hardware resources to assist developers in implementing robust safety functions.

AI 生成的摘要: The flash programmer writes to the RL78 microcontroller's on-chip flash memory using RL78 Protocol A via serial programming. It uses Raspberry Pi 4 Model B+ as the programmer hardware and requires program files in Motorola S format. The sample program supports single-line or dedicated UART interfaces. Development and operation have been confirmed on Raspberry Pi OS 64-bit with specific GCC and Make versions. Raspberry Pi settings include enabling multiple UARTs via config.txt. Build instructions use standard make commands. The document covers hardware interfaces, software functions, error codes, and flowcharts for flash programming.

AI 生成的摘要: Modbus communication over UART is implemented using the RL78 microcontroller and Renesas RS-485 transceiver, supporting both Modbus ASCII and RTU modes. The system uses GPIO to control send/receive permissions and TAU0 timers to measure intervals between characters and frames, ensuring proper timing in communication. The network operates in a single-master/multi-slave configuration with up to 247 slaves, each having a unique address. The document details hardware configurations, UART communication settings, supported function codes, and interrupt handling for both master and slave modes. It also includes software structure, constants, variables, and instructions for running the system in various environments. PCB design files typically bundled include BOM, schematic, and Gerber files.
