Product details
Overview
R5F565N9EDLJ#20 from Renesas Electronics is an RX65N Envision Kit evaluation board featuring the RX65N 32-bit microcontroller (32 MHz max, 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/OTG connectivity for rapid prototyping of industrial HMI and IoT edge devices.
For engineers reviewing the R5F565N9EDLJ#20 datasheet, R5F565N9EDLJ#20 pinout, R5F565N9EDLJ#20 application, or R5F565N9EDLJ#20 equivalent, this page delivers verified hardware specifications, firmware update workflow, supported demo projects (standard/benchmark), secure boot architecture, and board-level interface capabilities - all confirmed from Renesas' official Envision Kit documentation and firmware release notes.
Technical Context
The R5F565N9EDLJ#20 implements a dual-bank firmware update mechanism using the on-chip bootloader, enabling atomic bank swap and software reset without external programming tools. It integrates the RX65N MCU's hardware crypto acceleration (AES-128/256, SHA-256, TRNG) and tamper detection circuitry to enforce secure boot validation prior to application execution.
Firmware deployment relies on RSU (ROM Update) files stored on USB memory sticks, with automatic detection and selection via SW2 long-press (≥3 s). The board uses SW1/SW4 DIP switch configurations to enter bootloader mode (SW1-1 ON) or run user firmware (SW1-1 OFF), supporting field-upgradable embedded applications requiring high reliability and security compliance.

FAQ
What is the primary function of the R5F565N9EDLJ#20?
The R5F565N9EDLJ#20 is an evaluation board for the RX65N microcontroller, providing a complete hardware platform with LCD display, touch interface, USB host/OTG, and secure boot capability. It serves as a reference design and development tool for validating firmware, testing dual-bank updates, and prototyping secure industrial HMI applications using the R5F565N9EDLJ#20 hardware configuration.
How does firmware update work on the R5F565N9EDLJ#20?
Firmware update on the R5F565N9EDLJ#20 uses RSU (ROM Update) files loaded from a USB memory stick. Pressing SW2 for ≥3 seconds triggers automatic detection and installation of std.rsu or bench.rsu. The onboard bootloader performs signature verification, bank swapping, and software reset - all without external debug tools. This workflow is fully documented in Renesas' R5F565N9EDLJ#20 Envision Kit firmware guide.
Does the R5F565N9EDLJ#20 support secure boot, and how is it implemented?
Yes, the R5F565N9EDLJ#20 supports hardware-enforced secure boot via the RX65N MCU's integrated cryptographic accelerators. During power-on reset, the bootloader validates the digital signature of the firmware image using AES-128/256 decryption and SHA-256 hashing, combined with true random number generation. This ensures only authenticated code executes - a core security feature confirmed in the R5F565N9EDLJ#20 official documentation.
What demo firmware options are provided for the R5F565N9EDLJ#20?
The R5F565N9EDLJ#20 supports two prebuilt demo firmware variants: Standard Firmware (std.rsu) demonstrating capacitive touch, LCD rendering, and basic peripheral control; and Benchmark Firmware (bench.rsu) measuring CPU performance, memory bandwidth, and crypto throughput. Both are distributed as RSU files in the official rx65n_envisionkit.zip package released by Renesas for the R5F565N9EDLJ#20.
Can the R5F565N9EDLJ#20 be used for custom firmware development?
Yes, the R5F565N9EDLJ#20 supports full custom firmware development. Renesas provides source code for the secure bootloader (rx65n_secure_boot), standard demo project, and benchmark demo project inside rx65n_envisionkit.zip. Developers can build, sign, and convert MOT files to RSU format using convert.exe - enabling end-to-end customization, secure signing, and field-deployable updates on the R5F565N9EDLJ#20 platform.
