Product details
Overview
R5F565NEHDLK#20 from Renesas Electronics is an RX65N Envision Kit evaluation board featuring the RX65N 32-bit microcontroller (120 MHz, 2 MB flash, 384 KB RAM), integrated capacitive touch controller, and 4.3-inch WVGA LCD with resistive touch panel. It supports secure boot, dual-bank firmware update, and USB host/device connectivity for rapid prototyping of industrial HMI and IoT edge applications.
For engineers reviewing the R5F565NEHDLK#20 datasheet, R5F565NEHDLK#20 pinout, R5F565NEHDLK#20 application, or R5F565NEHDLK#20 equivalent, this page delivers verified hardware specifications, firmware update workflow details, supported demo projects (standard/benchmark), bootloader behavior, and OEM supply support - all specific to the R5F565NEHDLK#20 board revision.
Technical Context
The R5F565NEHDLK#20 implements a dual-bank firmware architecture enabling seamless over-the-air updates without system downtime: one bank runs active firmware while the other accepts new *.rsu images via USB memory stick. Bootloader initialization displays status messages on the onboard LCD and responds to SW2 long-press (≥3 s) to trigger bank swap and software reset.
Firmware deployment follows a strict data flow: source code in rx65n_envisionkit.zip is built into *.mot files (rx65n_secure_boot.mot, RX65N_EnvisionKit.mot, rx65n_envision_kit_demo.mot), converted to *.rsu using convert.exe, then loaded onto USB storage for automatic detection and installation - requiring no host PC connection during field update.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core MCU | RX65N 32-bit CPU @ 120 MHz - delivers real-time deterministic execution for industrial control loops and HMI rendering. |
| Memory | 2 MB on-chip flash (dual-bank configurable), 384 KB SRAM - enables secure boot + concurrent firmware validation and rollback. |
| Display Interface | 4.3-inch WVGA (480×272) LCD with resistive touch - supports direct GUI development without external display controller. |

FAQ
What is the primary function of the R5F565NEHDLK#20?
The R5F565NEHDLK#20 is an evaluation board for the RX65N microcontroller, not a standalone IC. Its primary function is to provide a complete hardware platform - including LCD, touch interface, USB host/device, and dual-bank flash - for developing and validating firmware for industrial HMIs and secure IoT edge devices. The R5F565NEHDLK#20 integrates all necessary peripherals to eliminate external interface design during early prototyping.
How does firmware update work on the R5F565NEHDLK#20?
Firmware update on the R5F565NEHDLK#20 uses a USB memory stick containing *.rsu files. When powered on with SW2 held ≥3 seconds, the bootloader detects std.rsu or bench.rsu, performs bank swap, and executes software reset. No debugger or PC connection is required - the R5F565NEHDLK#20 handles full image validation, write, and activation autonomously.
What demo firmware options are included with the R5F565NEHDLK#20?
The R5F565NEHDLK#20 supports two prebuilt demo firmware types: Standard Firmware (std.rsu) showcasing capacitive touch, graphics, and basic peripheral operation; and Benchmark Firmware (bench.rsu) measuring CPU performance, memory bandwidth, and crypto acceleration. Both are delivered as ready-to-load *.rsu files within the official Renesas download package.
Can the R5F565NEHDLK#20 be used for secure boot development?
Yes - the R5F565NEHDLK#20 includes the rx65n_secure_boot project in its source distribution, enabling developers to implement and test secure boot functionality using the RX65N's built-in cryptographic acceleration engine and trusted execution environment. The R5F565NEHDLK#20 bootloader validates firmware signatures before execution, supporting root-of-trust development workflows.
What are the required switch settings to enter bootloader programming mode on the R5F565NEHDLK#20?
To enter bootloader programming mode on the R5F565NEHDLK#20, set SW1-1 to ON, SW1-2 to OFF, and SW4-1 to OFF (SW4-2 state is irrelevant). This configuration enables serial download of new bootloader or firmware images via the onboard debug interface. Power-on reset with these switches engaged initiates the programming sequence for the R5F565NEHDLK#20.
