Product details
Overview
R5F5651CHDBP#20 from Renesas Electronics is an RX65N Group 32-bit microcontroller-based evaluation and demonstration platform - the RX65N Envision Kit - featuring a 120 MHz RXv2 CPU core, 2 MB flash, 512 KB SRAM, capacitive touch display, USB host/device interface, and integrated security boot loader firmware support. It targets rapid prototyping of secure industrial HMI and IoT edge node applications.
For engineers reviewing the R5F5651CHDBP#20 datasheet, R5F5651CHDBP#20 pinout, R5F5651CHDBP#20 application, or R5F5651CHDBP#20 equivalent, this page delivers verified hardware specifications, firmware update workflows, bank-swapping behavior, secure boot architecture, and OEM-ready supply chain support for embedded development teams.
Technical Context
The R5F5651CHDBP#20 implements a dual-bank firmware update mechanism using on-chip flash partitioning, enabling safe over-the-air (OTA) updates without system downtime. It integrates a pre-programmed secure boot loader (rx65n_secure_boot.mot) that validates RSU firmware signatures before execution.
Firmware deployment relies on USB memory stick insertion and physical button sequences (SW2 hold ≥3 s), triggering automatic detection of std.rsu or bench.rsu files. Boot mode selection is controlled by SW1-1/SW1-2/SW4-1 switch states during power-on reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit core @ 120 MHz - enables real-time deterministic execution for industrial control loops and HMI rendering. |
| Memory | 2 MB on-chip flash (dual-bank), 512 KB SRAM - supports A/B firmware updates with rollback capability. |
| Display Interface | Capacitive touch LCD controller with built-in driver - eliminates external touch controller ICs in HMI designs. |
| Security | Pre-flashed secure boot loader validating RSU signature - prevents unauthorized firmware execution at boot time. |
| Update Mechanism | USB mass storage-based RSU file loading via SW2 long-press - enables field-upgradable firmware without JTAG or debug tools. |
| Boot Mode Control | Hardware switches SW1-1/SW1-2/SW4-1 define boot source (internal flash, serial ROM, or user-defined) - allows flexible factory and field configuration. |

FAQ
What is the R5F5651CHDBP#20 used for?
The R5F5651CHDBP#20 is the official RX65N Envision Kit evaluation board from Renesas. It serves as a complete hardware reference platform for developing and validating applications based on the RX65N microcontroller - including secure boot implementation, capacitive touch HMI, dual-bank firmware updates, and USB-based field upgrades. The R5F5651CHDBP#20 includes pre-loaded firmware and documentation to enable immediate out-of-box evaluation.
How do I update firmware on the R5F5651CHDBP#20?
Firmware updates on the R5F5651CHDBP#20 are performed by inserting a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu), then holding SW2 for ≥3 seconds to trigger automatic detection and bank swap. The R5F5651CHDBP#20's secure boot loader validates each RSU file signature before flashing, ensuring only authorized firmware executes after reset.
Does the R5F5651CHDBP#20 support secure boot?
Yes, the R5F5651CHDBP#20 ships with a pre-programmed secure boot loader (rx65n_secure_boot.mot) that enforces cryptographic signature verification of all RSU firmware images before loading into flash. This ensures runtime integrity and prevents unauthorized code execution - a core requirement for industrial and IoT deployments where the R5F5651CHDBP#20 is deployed.
What firmware options are included with the R5F5651CHDBP#20?
The R5F5651CHDBP#20 supports two primary firmware modes: Standard Demo (std.rsu) for general-purpose HMI and peripheral validation, and Benchmark Demo (bench.rsu) optimized for performance measurement of CPU, memory, and graphics throughput. Both are delivered as downloadable ZIP archives containing source code, MOT files, and conversion tools (convert.exe) to generate RSU images compatible with the R5F5651CHDBP#20 boot loader.
Can I customize the firmware on the R5F5651CHDBP#20?
Yes - the R5F5651CHDBP#20 firmware is fully customizable. Renesas provides source code for the secure boot loader, standard demo, and benchmark demo projects inside rx65n_envisionkit.zip. Developers can rebuild MOT files using e2 studio or CS+ IDE, then convert them to RSU format using the included convert.exe tool for deployment on the R5F5651CHDBP#20.
