Product details
Overview
R5F5651CHDLK#20 from Renesas Electronics is an RX65N Envision Kit - a hardware evaluation platform for the RX65N microcontroller family, featuring a 128-pin LQFP package, integrated capacitive touch display, USB host interface for firmware updates, and dual-bank flash architecture supporting secure boot and over-the-air-style firmware swapping. It targets rapid prototyping of industrial HMI, secure IoT edge nodes, and functional safety–ready embedded applications.
For engineers reviewing the R5F5651CHDLK#20 datasheet, R5F5651CHDLK#20 pinout, R5F5651CHDLK#20 application, or R5F5651CHDLK#20 equivalent, this page provides verified board-level specifications, firmware update workflow details, secure boot implementation context, and OEM-ready supply support - all specific to the R5F5651CHDLK#20 Envision Kit configuration.
Technical Context
The R5F5651CHDLK#20 implements a dual-bank flash update mechanism with bank swap capability, enabling seamless firmware upgrades without system interruption. It integrates the RX65N MCU (32-bit RXv2 core, up to 120 MHz, 2 MB flash, 512 KB RAM) and supports secure boot via the rx65n_secure_boot project included in the official firmware bundle.
Firmware loading occurs via USB memory stick using *.rsu files (e.g., std.rsu, bench.rsu), processed by a dedicated bootloader that validates and installs images into primary or secondary flash banks. Boot mode selection is controlled by SW1 and SW4 DIP switch settings, with SW2 used for manual bank swap initiation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the R5F5651CHDLK#20?
The R5F5651CHDLK#20 is the official Renesas RX65N Envision Kit evaluation board - a complete hardware platform including the RX65N microcontroller in 128-pin LQFP, capacitive touch display, USB host port, and preloaded secure bootloader. It is not a semiconductor component but a development tool intended for firmware validation and application prototyping.
Does the R5F5651CHDLK#20 support secure boot?
Yes, the R5F5651CHDLK#20 supports secure boot through the rx65n_secure_boot project included in the official firmware bundle. This bootloader validates digital signatures of *.rsu firmware images before loading them into flash, ensuring only authenticated code executes on the R5F5651CHDLK#20.
How do I update firmware on the R5F5651CHDLK#20?
Firmware updates on the R5F5651CHDLK#20 are performed by inserting a FAT32-formatted USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu). The onboard bootloader detects the files, allows selection via on-board buttons, and performs bank-swapped installation - no external debugger or PC connection required during runtime.
What are the switch settings for boot mode on the R5F5651CHDLK#20?
Boot mode on the R5F5651CHDLK#20 is configured using SW1 and SW4 DIP switches: standard operation requires SW1-1 OFF, SW1-2 OFF, SW4-1 OFF; programming mode (e.g., flashing bootloader) uses SW1-1 ON, SW1-2 OFF, SW4-1 OFF. These settings determine whether the R5F5651CHDLK#20 boots from internal flash or enters download mode.
Is the R5F5651CHDLK#20 compatible with Renesas e2 studio and CS+ IDEs?
Yes, the R5F5651CHDLK#20 is fully supported by Renesas e2 studio (Eclipse-based) and CS+ IDEs. Both tools provide debug, flash programming, and project templates aligned with the R5F5651CHDLK#20's dual-bank flash layout and secure boot configuration - enabling full firmware development and validation workflows.
