Product details
Overview
R5F5651EHDFC#30 from Renesas Electronics is a 32-bit RXv2 core microcontroller-based evaluation and development platform - the RX65N Envision Kit - featuring 2MB flash, 512KB RAM, integrated Ethernet MAC, USB 2.0 FS/HS, SDHI, and capacitive touch support. It targets secure IoT edge node prototyping with hardware encryption (AES-128/256, SHA, TRNG) and dual-bank firmware update capability.
For engineers reviewing the R5F5651EHDFC#30 datasheet, R5F5651EHDFC#30 pinout, R5F5651EHDFC#30 application, or R5F5651EHDFC#30 equivalent, this page details its firmware architecture, boot loader operation, dual-bank update flow, USB memory-based deployment, and secure boot implementation for industrial and connected device development.
Technical Context
The R5F5651EHDFC#30 board implements a dedicated secure boot loader (rx65n_secure_boot.mot) that validates firmware signatures before execution and enforces bank-swapped updates to prevent bricking. It supports two independent firmware banks - primary and secondary - each holding either Standard or Benchmark demo firmware in *.rsu format.
Firmware installation requires SW1-1 ON/SW1-2 OFF/SW4-1 OFF for bootloader entry, then power-on reset with all switches OFF to launch the active bank. USB memory stick insertion triggers automatic detection of *.rsu files; pressing SW2 for ≥3 seconds initiates bank swap and software reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RXv2 32-bit CPU @ 120 MHz - enables real-time deterministic execution for industrial control and protocol stacks. |
| Memory | 2 MB on-chip flash (dual-bank), 512 KB RAM - supports A/B firmware updates without external storage dependency. |
| Secure Features | AES-128/256, SHA-256, TRNG, and secure boot ROM - provides cryptographic root-of-trust for firmware authenticity verification. |
| Connectivity | Ethernet MAC (10/100), USB 2.0 FS/HS, SDHI, CAN FD - enables wired/wireless gateway and fieldbus integration. |
| Human Interface | Capacitive touch controller + 4.3" WVGA LCD - allows rapid UI prototyping for HMI applications without external controllers. |
| Firmware Format | *.rsu (Renamed *.mot via convert.exe) - signed, encrypted binary container validated by boot loader prior to execution. |

FAQ
What is the purpose of the R5F5651EHDFC#30 board?
The R5F5651EHDFC#30 is the RX65N Envision Kit - a fully assembled evaluation board for the RX65N microcontroller. It serves as a reference platform for developing secure, networked embedded applications using Renesas' RXv2 core, dual-bank firmware update, and hardware-accelerated cryptography. The R5F5651EHDFC#30 includes onboard debug interface, Ethernet PHY, USB connector, SD card slot, and capacitive touch display.
How does firmware update work on the R5F5651EHDFC#30?
Firmware update on the R5F5651EHDFC#30 uses a dual-bank mechanism managed by the secure boot loader. Users place *.rsu files (e.g., std.rsu or bench.rsu) on a USB memory stick, insert it into the board, and press SW2 for ≥3 seconds to trigger bank swap and software reset. The R5F5651EHDFC#30 validates signature and integrity before activating the new firmware image.
What tools are required to build custom firmware for the R5F5651EHDFC#30?
To build custom firmware for the R5F5651EHDFC#30, developers use Renesas e2 studio IDE with GCC or CC-RX compiler, along with the provided rx65n_envisionkit.zip source package containing boot loader (rx65n_secure_boot), standard demo, and benchmark demo projects. The convert.exe utility transforms compiled *.mot files into signed *.rsu images compatible with the R5F5651EHDFC#30 boot loader.
Does the R5F5651EHDFC#30 support secure boot and cryptographic acceleration?
Yes, the R5F5651EHDFC#30 implements hardware-based secure boot via ROM-resident code that verifies digital signatures of *.rsu firmware images before loading. It also integrates AES-128/256, SHA-256, and TRNG accelerators - all accessible through the RA/RI/RS drivers in the FSP (Flexible Software Package). These features are enabled and tested on the R5F5651EHDFC#30 out of the box.
Can the R5F5651EHDFC#30 be used for production design-in?
The R5F5651EHDFC#30 itself is an evaluation kit and not intended for production use. However, its reference schematics, layout files, and validated firmware stack directly inform production designs based on the RX65N MCU (e.g., R5F5651EADFC). Engineers use the R5F5651EHDFC#30 to verify functionality, timing, security flow, and peripheral integration before transitioning to custom PCBs with the same RX65N device.
