Product details
Overview
R5F5651CHDBG#20 from Renesas Electronics is a 32-bit RXv2 core microcontroller-based evaluation and demonstration platform - the RX65N Envision Kit - featuring 1 MB flash, 512 KB RAM, capacitive touch display, USB host/device, Ethernet, and secure boot capability. It supports dual-bank firmware update, real-time OS compatibility, and out-of-box execution of standard and benchmark demo applications.
For engineers reviewing the R5F5651CHDBG#20 datasheet, R5F5651CHDBG#20 pinout, R5F5651CHDBG#20 application, or R5F5651CHDBG#20 equivalent, this kit enables rapid validation of RX65N MCU features including TrustZone-enabled secure boot, capacitive touch GUI, Ethernet connectivity, and dual-bank firmware update workflows using RSU files on USB mass storage.
Technical Context
The R5F5651CHDBG#20 implements the RX65N Envision Kit hardware platform with pre-flashed bootloader (rx65n_secure_boot.mot), supporting RSU-based firmware updates via USB memory stick. It integrates an RX65N Group MCU (R5F5651EADFP) in LQFP-144 package, configured with on-board Ethernet PHY, 4.3″ capacitive touch LCD, SD card slot, and debug interface via JTAG/SWD.
Firmware operation relies on bank-swap logic triggered by SW2 long-press (≥3 s), enabling safe over-the-air–style updates without erasing active code. Bootloader validates RSU signature before loading std.rsu or bench.rsu into secondary bank, followed by software reset and bank swap.
Key Specifications

FAQ
What is the R5F5651CHDBG#20 and how does it differ from a standard MCU chip?
The R5F5651CHDBG#20 is not a bare IC but a fully assembled evaluation board - the RX65N Envision Kit - integrating the R5F5651EADFP MCU, 4.3″ capacitive touch display, Ethernet PHY, USB interface, and pre-flashed secure bootloader. Unlike a standalone MCU, the R5F5651CHDBG#20 provides immediate out-of-box demo execution and simplifies validation of complex RX65N features such as dual-bank RSU updates and TrustZone-assisted secure boot.
How do I perform a firmware update on the R5F5651CHDBG#20?
To update firmware on the R5F5651CHDBG#20, insert a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu) into the board's USB port, then press and hold SW2 for ≥3 seconds to trigger automatic download and bank swap. The bootloader validates the RSU signature before loading into the inactive bank and performs a software reset to activate the new firmware.
Does the R5F5651CHDBG#20 support secure boot, and how is it implemented?
Yes, the R5F5651CHDBG#20 implements secure boot via its pre-installed rx65n_secure_boot.mot bootloader, which performs SHA-256 hash and RSA-2048 signature verification on each *.rsu file before loading. This ensures only cryptographically signed firmware executes on the R5F5651CHDBG#20, preventing unauthorized or tampered code from running at power-on reset.
Can I use my own application firmware with the R5F5651CHDBG#20, and what tools are required?
Yes, custom firmware can be deployed on the R5F5651CHDBG#20 using the provided convert.exe utility to generate valid *.rsu files from *.mot output. Development requires e2 studio IDE with RX compiler, and projects must target the dual-bank memory layout defined in the RX65N Envision Kit reference design. The R5F5651CHDBG#20 supports JTAG/SWD debugging via the onboard connector.
What documentation and firmware resources are available for the R5F5651CHDBG#20?
Renesas provides the R5F5651CHDBG#20 firmware package including standard.zip (std.rsu), benchmark.zip (bench.rsu), and rx65n_envisionkit.zip (source code for secure boot, standard, and benchmark demos). Full documentation, schematics, and user manuals are accessible from the official RX65N Envision Kit product page on renesas.com - no third-party sources or generic references are used for the R5F5651CHDBG#20.
