Product details
Overview
R5F565NCDDBG#20 from Renesas Electronics is an evaluation kit board for the RX65N microcontroller group, featuring a 32-bit RXv2 CPU core, 2MB flash, 512KB RAM, and integrated security functions including Secure Boot and AES-128 encryption. It includes a 4.3-inch capacitive touch LCD, USB host/device interface, SD card slot, and Ethernet PHY for rapid prototyping of industrial HMI and secure IoT edge devices.
For engineers reviewing the R5F565NCDDBG#20 datasheet, R5F565NCDDBG#20 pinout, R5F565NCDDBG#20 application, or R5F565NCDDBG#20 equivalent, this page provides verified firmware update workflows, bank-swapping behavior, boot loader initialization sequence, USB memory-based field update capability, and secure demo project structure - all confirmed from Renesas' official RX65N Envision Kit documentation.
Technical Context
The R5F565NCDDBG#20 implements dual-bank firmware update via hardware-controlled bank swap triggered by SW2 press ≥3 seconds, enabling safe over-the-air (OTA) updates without bricking. Its boot loader (rx65n_secure_boot.mot) validates RSU firmware signatures before execution and supports both standard and benchmark demo binaries (std.rsu / bench.rsu).
Firmware installation follows a strict data flow: source code imported from rx65n_envisionkit.zip → built into MOT files → converted to RSU using convert.exe → loaded via USB memory stick → auto-detected and installed on power-on reset with specific SW1/SW4 switch states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Form Factor | Evaluation board with 4.3-inch capacitive touch LCD and SD/Ethernet/USB interfaces. |
| Firmware Update Method | USB memory stick-based auto-detection and installation of *.rsu files (std.rsu or bench.rsu). |
| Boot Loader Trigger | SW2 held ≥3 seconds initiates bank swap and software reset; SW1-1/SW1-2/SW4-1 switch states define boot mode. |
| Dual-Bank Support | Primary and secondary flash banks enable atomic firmware updates with rollback capability. |
| Secure Boot Enforcement | Boot loader verifies digital signature of RSU firmware before loading - prevents unauthorized code execution. |
| Supported Demo Projects | Standard demo (HMI control), benchmark demo (performance profiling), and secure boot loader project included in rx65n_envisionkit.zip. |

FAQ
What is the R5F565NCDDBG#20 used for?
The R5F565NCDDBG#20 is an evaluation board for the RX65N MCU, intended for developing secure industrial HMIs and validating dual-bank firmware update workflows. It enables rapid prototyping of applications requiring AES-128 encryption, Secure Boot, and touch-based user interfaces - all supported out-of-box by the standard and benchmark demo projects included with the R5F565NCDDBG#20.
How does firmware update work on the R5F565NCDDBG#20?
Firmware update on the R5F565NCDDBG#20 uses USB memory stick auto-detection: insert a USB stick containing std.rsu or bench.rsu, power-cycle with SW1-1 off/SW1-2 off/SW4-1 off, then hold SW2 ≥3 seconds to trigger bank swap and software reset. The boot loader validates RSU signatures before loading - a process fully documented in Renesas' official R5F565NCDDBG#20 firmware update guide.
What demo firmware is included with the R5F565NCDDBG#20?
The R5F565NCDDBG#20 supports two prebuilt demo firmware types: Standard Firmware (std.rsu) for HMI control and Benchmark Firmware (bench.rsu) for performance profiling. Both are generated from source code in rx65n_envisionkit.zip, built as MOT files, and converted to RSU format using convert.exe - all steps validated for the R5F565NCDDBG#20.
Does the R5F565NCDDBG#20 support Secure Boot?
Yes, the R5F565NCDDBG#20 implements hardware-enforced Secure Boot via its integrated boot loader (rx65n_secure_boot.mot), which validates digital signatures of all RSU firmware before execution. This ensures only authenticated code runs on the RX65N MCU - a core security feature confirmed in the official R5F565NCDDBG#20 documentation and enabled by default on the board.
What switch settings control boot mode on the R5F565NCDDBG#20?
Boot mode on the R5F565NCDDBG#20 is controlled by SW1 and SW4: standard operation requires SW1-1 off, SW1-2 off, and SW4-1 off; download mode (for flashing boot loader) requires SW1-1 on, SW1-2 off, and SW4-1 off. These exact switch configurations are specified in the R5F565NCDDBG#20 hardware setup guide and verified across all firmware update procedures.
