Product details
Overview
R5F565N4BDLJ#20 from Renesas Electronics is an RX65N Envision Kit - a hardware evaluation platform for the RX65N microcontroller family, featuring a 128-pin LQFP package, integrated capacitive touch display, USB memory interface, and dual-bank secure boot loader supporting std.rsu and bench.rsu firmware updates. It enables rapid validation of industrial HMI, secure firmware update, and real-time RTOS-based applications.
For engineers reviewing the R5F565N4BDLJ#20 datasheet, R5F565N4BDLJ#20 pinout, R5F565N4BDLJ#20 application, or R5F565N4BDLJ#20 equivalent, this page provides verified board-level specifications, firmware update workflow, secure boot architecture, dual-bank operation, and OEM-ready supply support - all specific to the R5F565N4BDLJ#20 Envision Kit revision.
Technical Context
The R5F565N4BDLJ#20 implements a dual-bank flash update mechanism with bank swap and software reset, triggered via SW2 hold (≥3 sec) or USB memory stick auto-detection. It executes pre-validated RX65N firmware images (.rsu) built from standard and benchmark demo projects, including rx65n_secure_boot, standard, and benchmark source folders.
Firmware installation follows a strict data flow: MOT files (rx65n_secure_boot.mot, RX65N_EnvisionKit.mot, rx65n_envision_kit_demo.mot) are converted to .rsu using convert.exe, renamed to std.rsu or bench.rsu, then loaded onto USB memory. Boot loader initialization occurs on power-on reset with SW1-1 off, SW1-2 off, SW4-1 off.
Key Specifications

FAQ
What is the R5F565N4BDLJ#20 used for?
The R5F565N4BDLJ#20 is an evaluation board - not a chip - designed to accelerate development with the RX65N microcontroller. It supports secure dual-bank firmware updates, capacitive touch UI validation, and real-time RTOS testing. Engineers use the R5F565N4BDLJ#20 to verify bootloader behavior, benchmark performance, and qualify hardware before custom PCB design.
Does the R5F565N4BDLJ#20 include source code?
Yes. The R5F565N4BDLJ#20 is distributed with full source code in rx65n_envisionkit.zip, including three independent projects: rx65n_secure_boot (bootloader), standard (HMI demo), and benchmark (performance test). All are buildable in e2 studio using Renesas' CC-RX or GCC toolchains - no binary-only dependencies.
How does firmware update work on the R5F565N4BDLJ#20?
Firmware updates on the R5F565N4BDLJ#20 use a dual-bank mechanism: std.rsu loads to secondary bank and swaps on reset; bench.rsu operates similarly. Updates are initiated by inserting a USB memory stick containing *.rsu files, or by holding SW2 ≥3 seconds. The boot loader validates and installs firmware without external debuggers.
What are the required switch settings for boot mode on the R5F565N4BDLJ#20?
For normal operation and firmware update, SW1-1 must be OFF, SW1-2 OFF, and SW4-1 OFF (SW4-2 is don't-care). To download the boot loader via serial, SW1-1 must be ON, SW1-2 OFF, SW4-1 OFF. These settings directly control the RX65N's boot vector selection and are documented in the R5F565N4BDLJ#20 hardware manual.
Is the R5F565N4BDLJ#20 compatible with Renesas e2 studio?
Yes. The R5F565N4BDLJ#20 is fully supported in Renesas e2 studio v7.8+ with RX Family Device Drivers and FSP (Flexible Software Package). Projects included with the R5F565N4BDLJ#20 - such as standard and benchmark demos - import and build natively, and debugging uses the on-board JTAG/SWD interface.
