- Application NoteAI-generated Summary: 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.Related Files:

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.

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.Related Files:
- Application NoteAI-generated Summary: 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.

- Application NoteAI-generated Summary: 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.Related Files:
- Application NoteAI-generated Summary: The document details the UART functionality of the RL78/G10 microcontroller, including peripheral functions such as UART reception and transmission timing generation using the serial array unit and timer array unit. It provides timing charts for UART reception and transmission, explains control signals, and lists operation check conditions including the microcontroller model, clock frequency, operating voltage, development environments, and target board. It also references a related initialization application note.Related Files:
- Application NoteAI-generated Summary: The document explains how to implement an interval timer using the watchdog timer (WDT) on the RL78/G10 microcontroller. The timer can be set from 100 ms to 500 ms in 100 ms increments by pressing a switch (SW1). The main program waits for WDT interrupts in STOP mode, counting the number of interrupts to calibrate the interval time. The LED toggles its state based on the set interval. Detailed calibration methods and operation flow are provided, including how the WDT interrupt period is measured and used to adjust the timer.Related Files:
- Application NoteAI-generated Summary: The document explains how to perform A/D conversion on four analog input pins, store results in on-chip RAM, and transmit averaged conversion data via UART. It measures the UART baud rate by capturing pulse intervals on the TI00 pin using Timer Array Unit 0. The baud rate calculation adjusts prescaler and divider values to minimize error. Data is sent as ASCII characters, with three characters per analog input. The document includes circuit configurations, timing charts, and program setup details for baud rate measurement and A/D conversion result handling.Related Files:

- Application NoteAI-generated Summary: 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.Related Files:
- Application NoteAI-generated Summary: 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.View More (97)
