RL78/L1A Block Diagram

描述

The ultra-low power RL78/L1A microcontroller family with embedded LCD has enhanced analog peripherals such as 12-bit A/D converters, 12-bit D/A converters, comparators, high accuracy rail-to-rail operational amplifiers with switch fabrics and comes with memory up to 128kb flash. Using the smart features like DTC and ELC a lot of peripherals can be connected internally to reduce CPU workload and can save overall power consumption.

Available in 80-pin and 100-pin LFQFP packages, this MCU line has been developed especially for healthcare biosensing applications such as blood glucose meters. It is also suitable for many other appliances which need low power with LCD and rich analog peripherals.

RL78 Family SHA Hash Function Library: Introduction Guide Rev.2.03
PDF 522 KB R20AN0211EJ0203 Rev.2.03 日本語 2025年8月01日
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.

How to use IAR Systems compiler in e² studio
PDF 666 KB R20AN0733EJ0200 Rev.2.00 日本語 2024年9月13日
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.

Flash programmer with Raspberry Pi (RL78 Protocol A)
PDF 569 KB R01AN7209EJ0100 Rev.1.00 日本語 2024年2月29日
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.

RL78/G14 Modbus ASCII/RTU Application Note Rev.2.00
PDF 1.55 MB R01AN5380EJ0200 Rev.2.00 日本語 2023年10月20日
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.

RL78 Flash Programmer (RL78 Protocol B) Rev.1.00
PDF 797 KB R01AN6782EJ0100 Rev.1.00 日本語 2023年2月16日
AI 生成的摘要: The document explains how to program the internal flash memory of RL78 microcontrollers using RL78 Protocol B. It supports serial programming with Motorola S-format files and offers two modes: online mode, where the host PC writes via USB connection, and offline mode, where writing occurs by pressing a switch on the evaluation board after preloading data. The sample program runs on the RL78/G23-128p Fast Prototyping Board and requires specific development environments and tools, including Renesas Flash Driver RL78 Type01. Detailed hardware configurations, communication protocols, and software settings are provided for effective flash programming.

AI 生成的摘要: The document explains how to program the internal flash memory of RL78 microcontrollers supporting RL78 Protocol C using serial programming. It details two modes: online mode, where a host PC writes to the target MCU via USB and UART, and offline mode, where the program file is stored in the RL78/G23 code flash and written by pressing a switch on the evaluation board. The sample program supports Motorola S-format files and works with the RL78/G23-128p Fast Prototyping Board. Development environments, hardware configurations, communication protocols, LED status indicators, error codes, and software structures are also covered. The Renesas Flash Driver RL78 Type01 is used for flash memory reprogramming.

AI 生成的摘要: The RL78 Flash Programmer supports writing program data to the internal flash memory of RL78 microcontrollers using RL78 Protocol A. It operates in two modes: online mode, which programs the target MCU via USB connection with a host PC, and offline mode, which programs using stored data on the evaluation board without a host PC. The programming uses Motorola S-format files and supports up to 512 KB in offline mode, with larger sizes requiring online mode. The environment includes the RL78/G23-128p Fast Prototyping Board, Renesas Flash Driver RL78 Type01, and various IDEs and compilers. The document details communication protocols, hardware configurations, software structure, and error handling for efficient flash programming.
