Product details
Overview
R5F5651EHDBG#20 from Renesas Electronics is an RX65N Envision Kit - a hardware evaluation platform for the RX65N microcontroller family, featuring a 32-bit RXv2 core, 1MB flash, 128KB RAM, integrated security engine (AES/SHA/RSA), and capacitive touch support. It includes on-board debugger (E2 Lite), USB interface, LCD display, and expansion headers for rapid prototyping of secure industrial HMI applications.
For engineers reviewing the R5F5651EHDBG#20 datasheet, R5F5651EHDBG#20 pinout, R5F5651EHDBG#20 application, or R5F5651EHDBG#20 equivalent, this page provides verified hardware specifications, firmware update workflow, boot loader behavior, bank-swapping capability, and secure boot architecture details essential for HMI development, functional safety validation, and dual-bank OTA updates.
Technical Context
The R5F5651EHDBG#20 implements a dual-bank firmware update mechanism using the onboard RX65N's flash memory partitioning, enabling safe over-the-air (OTA) updates without system downtime. It supports both standard and benchmark demo firmware images (.rsu), each built from verified source code in rx65n_envisionkit.zip.
Firmware installation relies on a dedicated boot loader (rx65n_secure_boot.mot), pre-programmed to recognize .rsu files from USB mass storage, perform signature verification, validate CRC, and execute bank swap with software reset - all triggered by SW2 long-press or menu selection.
Key Specifications

FAQ
What is the primary function of the R5F5651EHDBG#20?
The R5F5651EHDBG#20 is a fully assembled evaluation board - not a standalone IC - providing hardware access to the RX65N microcontroller's security peripherals, touch interface, and dual-bank flash architecture. It serves as a reference platform for developing and validating secure firmware updates, HMI applications, and cryptographic workflows before custom PCB design.
How does firmware update work on the R5F5651EHDBG#20?
Firmware update on the R5F5651EHDBG#20 uses a preloaded boot loader that reads .rsu files from a USB memory stick. Users select either std.rsu or bench.rsu via on-screen menu or SW2 long-press, triggering CRC check, signature verification, and atomic bank swap followed by software reset - ensuring no bricking during field updates.
Does the R5F5651EHDBG#20 support secure boot?
Yes, the R5F5651EHDBG#20 leverages the RX65N's built-in security engine to enforce secure boot. The boot loader verifies digital signatures of .rsu firmware images using RSA-2048 and validates integrity via SHA-256 before loading into flash - a capability confirmed in the rx65n_secure_boot project included in rx65n_envisionkit.zip.
What development tools are compatible with the R5F5651EHDBG#20?
The R5F5651EHDBG#20 is supported by Renesas e2 studio IDE, CS+ (formerly CubeSuite+), and GCC-based toolchains. It integrates seamlessly with the E2 Lite debugger for flash programming, real-time debugging, and trace analysis - all without requiring additional debug probes.
Where can I obtain the source code for the demo firmware on the R5F5651EHDBG#20?
The complete source code for standard, benchmark, and secure boot firmware for the R5F5651EHDBG#20 is provided in rx65n_envisionkit.zip, available from the official Renesas RX65N Envision Kit webpage. This includes buildable projects for rx65n_secure_boot, standard, and benchmark folders - enabling full customization and security validation.
