Product details
Overview
R5F5651EHDLK#20 from Renesas Electronics is a 32-bit RXv2 core microcontroller-based evaluation and development kit - the RX65N Envision Kit - featuring 2MB flash, 384KB RAM, capacitive touch display, USB host/device, Ethernet, SD card slot, and secure boot capability. It supports real-time OS, TLS/SSL, and TrustZone-enabled firmware updates for industrial HMI and IoT edge node prototyping.
For engineers reviewing the R5F5651EHDLK#20 datasheet, R5F5651EHDLK#20 pinout, R5F5651EHDLK#20 application, or R5F5651EHDLK#20 equivalent, this page provides verified hardware specifications, firmware update workflow, secure boot architecture, dual-bank OTA mechanism, and toolchain integration details essential for rapid evaluation and production-ready design validation.
Technical Context
The R5F5651EHDLK#20 implements the RX65N Envision Kit platform with a pre-flashed secure boot loader (rx65n_secure_boot.mot), enabling authenticated firmware updates via USB memory stick using *.rsu files. It supports bank-swap execution between primary and secondary flash banks without external debugger.
Firmware deployment follows a strict data flow: source code in rx65n_envisionkit.zip → compiled MOT files → converted to *.rsu via convert.exe → loaded onto USB stick → auto-detected and installed on power-on reset or SW2 long-press (≥3 sec). Boot mode is controlled by SW1/SW4 DIP switch settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RXv2 32-bit CPU @ 120 MHz - delivers deterministic real-time performance for industrial control loops and GUI rendering. |
| Memory | 2 MB on-chip flash (dual-bank), 384 KB RAM - enables A/B firmware updates with zero downtime and rollback capability. |
| Display Interface | Capacitive touch LCD controller with RGB interface - supports 480×272 resolution displays for HMI development. |
| Connectivity | Ethernet MAC + PHY, USB 2.0 host/device, SDIO - allows direct connection to networks, peripherals, and storage without bridge ICs. |
| Security | Secure boot loader with RSA-2048 signature verification - prevents unauthorized firmware execution at power-on reset. |
| Firmware Format | RSU (Renesas Secure Update) file format - encapsulates signed binary, metadata, and update policy for field-deployable OTA. |

FAQ
What is the R5F5651EHDLK#20 and how does it differ from standard RX65N MCUs?
The R5F5651EHDLK#20 is not a standalone MCU but the full RX65N Envision Kit evaluation board - a ready-to-run hardware platform with pre-flashed secure boot loader, capacitive touch display, Ethernet PHY, and USB host/device interfaces. Unlike bare RX65N chips, R5F5651EHDLK#20 includes all supporting circuitry, firmware tools, and documentation needed for immediate evaluation of secure firmware updates and HMI development.
How do I perform a firmware update on the R5F5651EHDLK#20?
To update firmware on the R5F5651EHDLK#20, copy a valid *.rsu file (e.g., std.rsu or bench.rsu) onto a FAT32-formatted USB memory stick, insert it into the kit's USB-A port, then either power-cycle with SW1-1 OFF/SW1-2 OFF/SW4-1 OFF or hold SW2 for ≥3 seconds. The boot loader automatically detects and installs the firmware into the inactive flash bank.
What firmware files are included with the R5F5651EHDLK#20 and where are they sourced?
The R5F5651EHDLK#20 ships with pre-installed standard and benchmark demo firmware. Full source packages - including rx65n_secure_boot, standard, and benchmark projects - are distributed as rx65n_envisionkit.zip from Renesas' official website. These contain MOT files converted to *.rsu using the provided convert.exe utility for field updates.
Does the R5F5651EHDLK#20 support secure over-the-air (OTA) updates in production systems?
Yes - the R5F5651EHDLK#20 implements a production-grade secure OTA framework using RSU files signed with RSA-2048. Its dual-bank flash architecture and verified boot loader allow authenticated, atomic firmware swaps. While the kit itself uses USB memory for update delivery, the same RSU mechanism can be adapted for network-based OTA in deployed systems.
What development tools are required to build custom firmware for the R5F5651EHDLK#20?
Custom firmware for the R5F5651EHDLK#20 requires Renesas e2 studio IDE (v7.8+), RX Family GCC compiler or CC-RX compiler, and the RX65N Group Device Driver Library. Projects must generate MOT output files, which are then converted to *.rsu using the official convert.exe tool included in the rx65n_envisionkit.zip package.
