Product details
Overview
R5F565NCHDBG#20 from Renesas Electronics is a 32-bit RX65N Group microcontroller-based evaluation and demonstration platform - the RX65N Envision Kit - featuring an RX65N MCU (R5F565NEDDFP), 1MB Flash, 192KB RAM, capacitive touch LCD, USB host/device, Ethernet PHY, and secure boot capability. It supports rapid prototyping of industrial HMI, IoT edge nodes, and secure firmware update applications.
For engineers reviewing the R5F565NCHDBG#20 datasheet, R5F565NCHDBG#20 pinout, R5F565NCHDBG#20 application, or R5F565NCHDBG#20 equivalent, this page delivers verified hardware specifications, firmware update workflows, board-level interfaces, supported demo firmware variants (Standard/Benchmark), and OEM-ready supply support - all specific to the R5F565NCHDBG#20 Envision Kit configuration.
Technical Context
The R5F565NCHDBG#20 implements a dual-bank firmware update architecture using on-chip Flash with bank swap functionality, enabling safe over-the-air (OTA) updates without system downtime. It integrates a dedicated secure boot loader (rx65n_secure_boot.mot) that validates RSU firmware images before execution.
Firmware deployment relies on USB memory stick ingestion: standard.zip yields std.rsu for primary bank operation; benchmark.zip yields bench.rsu for secondary bank execution. Boot mode selection is controlled by SW1 and SW4 DIP switch settings, while SW2 initiates forced bank swap and software reset.

FAQ
What is the R5F565NCHDBG#20 used for?
The R5F565NCHDBG#20 is the official RX65N Envision Kit evaluation board from Renesas. It is used for developing, debugging, and validating firmware for the RX65N microcontroller - especially for secure boot implementation, dual-bank firmware updates, capacitive touch HMI, and Ethernet-enabled IoT edge applications. The R5F565NCHDBG#20 includes all necessary hardware interfaces and preloaded boot firmware to begin development immediately.
How do I update firmware on the R5F565NCHDBG#20?
Firmware update on the R5F565NCHDBG#20 is performed by inserting a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu) into the board's USB port. With correct DIP switch settings (SW1-1 off, SW1-2 off, SW4-1 off), power-on triggers automatic detection. Pressing SW2 for 3 seconds initiates bank swap and software reset. The R5F565NCHDBG#20 executes the new firmware from the alternate bank after validation.
What firmware formats does the R5F565NCHDBG#20 support?
The R5F565NCHDBG#20 exclusively uses the RSU (Renesas Secure Update) format for field firmware updates. RSU files are generated by converting MOT-format output binaries using the provided convert.exe tool. Standard and Benchmark demo firmware are distributed as standard.zip and benchmark.zip archives, each containing validated RSU images for primary and secondary Flash banks. The R5F565NCHDBG#20 bootloader only accepts cryptographically signed RSU files.
Does the R5F565NCHDBG#20 include source code for demos?
Yes - the R5F565NCHDBG#20 is supported by rx65n_envisionkit.zip, which contains full source code for three projects: rx65n_secure_boot (bootloader), standard (HMI demo), and benchmark (performance demo). All projects are built with e2 studio and include build scripts and documentation. This enables customization, security analysis, and integration of the R5F565NCHDBG#20 into proprietary development workflows.
What are the key hardware interfaces on the R5F565NCHDBG#20?
The R5F565NCHDBG#20 features a 4.3-inch capacitive touch LCD, USB-A host/device port, 10/100 Ethernet connector with integrated PHY, microSD slot, expansion headers compatible with Arduino UNO R3 and PMOD, and user switches (SW1–SW4) and LEDs. These interfaces allow direct evaluation of the RX65N MCU's peripheral capabilities without additional hardware - making the R5F565NCHDBG#20 ideal for proof-of-concept and pre-silicon validation.
