Product details
Overview
R5F56517BDBP#20 from Renesas Electronics is a 32-bit RXv2 core microcontroller-based evaluation and development kit - the RX65N Envision Kit - featuring 2MB flash, 512KB RAM, capacitive touch display, USB host/device, Ethernet, and secure boot capability. It supports dual-bank firmware update, real-time OS compatibility, and out-of-box operation with preloaded standard and benchmark demo firmware.
For engineers reviewing the R5F56517BDBP#20 datasheet, R5F56517BDBP#20 pinout, R5F56517BDBP#20 application, or R5F56517BDBP#20 equivalent, this page provides verified hardware specifications, firmware update workflow, secure boot architecture, dual-bank operation details, and developer toolchain integration guidance for industrial HMI and connected device prototyping.
Technical Context
The R5F56517BDBP#20 implements the RX65N group MCU in a physical evaluation board form factor, integrating the R5F56517BDFA chip (100-pin LQFP) with on-board debug interface, 4.3″ capacitive touch LCD, microSD slot, Ethernet PHY, and USB Type-A/B connectors. Firmware updates are executed via USB memory stick using *.rsu files processed by an embedded secure boot loader.
Boot operation requires specific SW1/SW4 switch configurations: SW1-1 ON + SW1-2 OFF + SW4-1 OFF enables bootloader download mode; SW1-1 OFF + SW1-2 OFF + SW4-1 OFF boots into user firmware. Dual-bank swap is triggered by holding SW2 for ≥3 seconds, initiating bank swap and software reset without external tools.

FAQ
What is the R5F56517BDBP#20 and how does it differ from a standard MCU?
The R5F56517BDBP#20 is not a bare IC but the full RX65N Envision Kit evaluation board - a ready-to-run hardware platform built around the R5F56517BDFA MCU. Unlike a standalone microcontroller, R5F56517BDBP#20 includes integrated peripherals (LCD, Ethernet, USB host), debug circuitry, and preloaded secure boot firmware, enabling immediate evaluation without custom PCB design or bring-up effort.
How do I perform a firmware update on the R5F56517BDBP#20?
To update firmware on the R5F56517BDBP#20, insert a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu) into the board's USB-A port. Power-cycle with SW1-1 OFF/SW1-2 OFF/SW4-1 OFF to boot into user firmware, then hold SW2 for ≥3 seconds to trigger bank swap and automatic installation. No PC or debugger required.
What firmware files are included with the R5F56517BDBP#20 and where are they sourced?
The R5F56517BDBP#20 ships with preloaded standard and benchmark demo firmware. Additional firmware - including standard.zip (std.rsu), benchmark.zip (bench.rsu), and rx65n_envisionkit.zip (source projects and convert.exe) - is available from the official Renesas RX65N Envision Kit webpage. All *.rsu files are validated by Renesas and signed for secure boot verification on R5F56517BDBP#20.
Does the R5F56517BDBP#20 support secure boot, and how is it implemented?
Yes, the R5F56517BDBP#20 implements hardware-enforced secure boot using on-chip ROM code that validates SHA-256 hashes and AES-128 decrypted signatures of *.rsu firmware images prior to execution. This prevents unauthorized or tampered firmware from running, ensuring trusted execution from power-on reset - a foundational security feature of the R5F56517BDBP#20 platform.
Can I develop custom applications for the R5F56517BDBP#20, and what tools are required?
Yes, the R5F56517BDBP#20 supports full custom application development using Renesas e2 studio IDE, GCC-RX compiler, and CS+ toolchain. Source code for standard and benchmark demos is provided in rx65n_envisionkit.zip, and convert.exe enables conversion of compiled *.mot files into secure *.rsu images compatible with the R5F56517BDBP#20 bootloader and dual-bank architecture.
