Product details
Overview
R5F5651CDDBP#20 from Renesas Electronics is a 32-bit RXv2 core microcontroller-based evaluation and development platform - the RX65N Envision Kit - featuring 2MB flash, 512KB RAM, capacitive touch LCD, Ethernet PHY, USB host/device, SD card slot, and secure boot capability. It targets industrial HMI, IoT edge node prototyping, and functional safety-ready embedded applications.
For engineers reviewing the R5F5651CDDBP#20 datasheet, R5F5651CDDBP#20 pinout, R5F5651CDDBP#20 application, or R5F5651CDDBP#20 equivalent, this page delivers verified hardware specifications, firmware update workflow, on-board peripheral mapping, secure boot architecture, and OEM-ready supply support - all specific to the R5F5651CDDBP#20 kit configuration.
Technical Context
The R5F5651CDDBP#20 implements the RX65N Group MCU (R5F5651C) in a 145-pin LQFP package with integrated 2MB flash and 512KB SRAM. It supports dual-bank firmware update via RSU files loaded from USB memory stick, enabling safe field updates without halting operation.
Bootloader functionality includes secure boot validation using SHA-256 and RSA-2048 signature verification, bank-swapping logic triggered by SW2 hold (>3s), and automatic firmware selection from std.rsu or bench.rsu files. The kit provides direct access to all MCU pins through expansion headers and preloaded demo firmware for rapid validation.

The R5F5651CDDBP#20 includes all necessary hardware and documentation to begin coding within minutes.
Does the R5F5651CDDBP#20 support secure boot?
Yes, the R5F5651CDDBP#20 implements secure boot using SHA-256 hashing and RSA-2048 signature verification on firmware images loaded at power-on reset. This ensures only cryptographically signed firmware executes, protecting against tampering or unauthorized updates. The R5F5651CDDBP#20 bootloader enforces this check before launching either standard or benchmark demo firmware.
How do I update firmware on the R5F5651CDDBP#20?
Firmware updates on the R5F5651CDDBP#20 are performed by inserting a USB memory stick containing *.rsu files (e.g., std.rsu or benchxxx.rsu) and holding SW2 for >3 seconds to trigger bank swap and software reset. The R5F5651CDDBP#20 bootloader automatically detects and installs the selected firmware image into the inactive bank, ensuring zero-downtime updates.
What peripherals are accessible on the R5F5651CDDBP#20?
The R5F5651CDDBP#20 provides full access to the RX65N MCU's peripherals via 2×20-pin expansion headers, including UART, SPI, I²C, CAN, ADC, GPIO, and PWM channels. On-board peripherals include a 4.3-inch capacitive touch LCD, Ethernet PHY (RMII), USB 2.0 host/device port, SD card slot, and user LEDs/switches - all directly mapped and documented for the R5F5651CDDBP#20.
Is source code provided with the R5F5651CDDBP#20?
Yes, the R5F5651CDDBP#20 distribution includes complete source code for the secure boot loader, standard demo project, and benchmark demo project in the rx65n_envisionkit.zip archive. Projects are structured in three folders: rx65n_secure_boot, standard, and benchmark - all compatible with Renesas e² studio and CS+ IDE. The R5F5651CDDBP#20 firmware build flow uses convert.exe to generate *.rsu files from *.mot outputs.
