Product details
Overview
R5F56517FDLJ#20 from Renesas Electronics is an RX65N Group 32-bit microcontroller-based evaluation and demonstration platform - the RX65N Envision Kit - featuring a 120 MHz RXv2 CPU core, 2 MB flash, 384 KB RAM, capacitive touch LCD, USB host/device, Ethernet MAC, and secure boot capability. It serves as a hardware reference for rapid prototyping of industrial HMI, IoT edge nodes, and secure firmware-updatable embedded systems.
For engineers reviewing the R5F56517FDLJ#20 datasheet, R5F56517FDLJ#20 pinout, R5F56517FDLJ#20 application, or R5F56517FDLJ#20 equivalent, this page provides verified technical context, firmware update workflow details, supported demo configurations (standard/benchmark), secure boot architecture, and board-level interface mapping - all specific to the R5F56517FDLJ#20 Envision Kit revision.
Technical Context
The R5F56517FDLJ#20 Envision Kit implements dual-bank firmware update via a dedicated secure bootloader (rx65n_secure_boot.mot), enabling atomic bank swap and software reset without external debugger. It supports RSU firmware images generated from MOT files using convert.exe, with automatic detection of std.rsu and bench.rsu on USB mass storage.
Hardware initialization includes SW1/SW4 DIP switch configuration for bootloader entry (SW1-1 ON) or normal boot (SW1-1 OFF), and SW2 long-press (≥3 s) to trigger bank swap and reboot. The board integrates an RX65N MCU in LQFP-176 package with on-board Ethernet PHY, microSD slot, and 4.3″ capacitive touch LCD.
Key Specifications

FAQ
What is the R5F56517FDLJ#20 and how does it differ from a standard RX65N MCU?
The R5F56517FDLJ#20 is not a standalone IC but the full RX65N Envision Kit - a ready-to-run evaluation board built around the RX65N MCU. Unlike bare R5F56517FDLJ devices, the R5F56517FDLJ#20 includes on-board peripherals (Ethernet PHY, LCD, USB connector), pre-flashed secure bootloader, and factory-tested firmware update infrastructure - enabling immediate evaluation without hardware assembly or toolchain setup.
How do I perform a firmware update on the R5F56517FDLJ#20?
To update firmware on the R5F56517FDLJ#20, insert a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu) into the board's USB port. Power-cycle with default DIP switches, then press and hold SW2 for ≥3 seconds to initiate bank swap and auto-load the new firmware. The R5F56517FDLJ#20 bootloader handles signature verification and atomic update without host PC intervention.
What firmware images are supported by the R5F56517FDLJ#20 bootloader?
The R5F56517FDLJ#20 bootloader natively supports two firmware types: Standard Demo (std.rsu) and Benchmark Demo (bench.rsu), both derived from MOT files via convert.exe. Each RSU image contains version metadata, digital signature, and encrypted payload validated prior to execution - ensuring only authorized firmware runs on the R5F56517FDLJ#20.
Does the R5F56517FDLJ#20 support secure boot, and how is it implemented?
Yes, the R5F56517FDLJ#20 implements secure boot via its pre-installed rx65n_secure_boot bootloader. This component verifies ECDSA signatures and SHA-256 hashes of incoming RSU firmware before loading, preventing unauthorized or tampered code execution. Secure boot is enabled by default and enforced on every R5F56517FDLJ#20 power-on or reset cycle.
Can I customize the demo firmware for the R5F56517FDLJ#20?
Yes - Renesas provides full source code for the R5F56517FDLJ#20 demo firmware in rx65n_envisionkit.zip, including the secure boot loader, standard demo, and benchmark demo projects. Developers can rebuild MOT files using e2 studio or CS+, convert them to RSU using convert.exe, and deploy custom firmware while retaining the R5F56517FDLJ#20's dual-bank update and security features.
