Product details
Overview
R5F565N7BDFB#30 from Renesas Electronics is a 32-bit RX65N Group microcontroller-based evaluation and demonstration kit - the RX65N Envision Kit - featuring an RX65N MCU (R5F565N7BDFB) in LQFP-144 package, 2 MB flash, 384 KB RAM, integrated capacitive touch controller, Ethernet MAC, USB 2.0 FS, and hardware encryption engine. It supports secure boot, dual-bank firmware update, and real-time OS-ready operation for industrial HMI development.
For engineers reviewing the R5F565N7BDFB#30 datasheet, R5F565N7BDFB#30 pinout, R5F565N7BDFB#30 application, or R5F565N7BDFB#30 equivalent, this page provides verified technical context, firmware update workflow, supported demo configurations (standard/benchmark), secure boot architecture, and board-level interface capabilities - all specific to the R5F565N7BDFB#30 Envision Kit hardware platform.
Technical Context
The R5F565N7BDFB#30 Envision Kit implements a dual-bank firmware update mechanism using internal flash partitioning, enabling safe over-the-air (OTA)-style updates via USB memory stick without interrupting active operation. Boot loader initialization occurs on power-on reset with SW1-1 off/SW1-2 off/SW4-1 off, and triggers automatic detection of *.rsu files (std.rsu or bench.rsu) from connected USB storage.
Firmware installation follows a strict data flow: source code projects (rx65n_secure_boot, standard, benchmark) are built into *.mot files, converted to *.rsu using convert.exe, then loaded onto USB media. Bank swap and software reset execute only after confirmed file selection and SW2 press (>3 s), ensuring atomicity and rollback safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RXv2 32-bit CPU core, 120 MHz max operation - enables deterministic real-time response for industrial control loops and HMI rendering. |
| Memory | 2 MB on-chip flash (dual-bank configurable), 384 KB SRAM - supports A/B firmware update with zero-downtime failover. |
| Secure Boot | Hardware-accelerated AES-128/256 and SHA-256 in ROM bootloader - validates firmware signature before execution to prevent unauthorized code injection. |
| Interface Support | Ethernet MAC (MII/RMII), USB 2.0 FS device/host, 4-channel capacitive touch - enables networked HMI with touch GUI and peripheral connectivity. |
| Firmware Format | RSU (Renesas Secure Update) binary format - cryptographically signed, versioned, and validated by onboard bootloader prior to bank swap. |
| Update Trigger | SW2 long-press (>3 s) initiates bank swap and software reset - ensures intentional, user-confirmed update with visual feedback on LCD. |

FAQ
What is the R5F565N7BDFB#30 and how does it differ from a standard MCU?
The R5F565N7BDFB#30 is not a standalone IC but the full RX65N Envision Kit - a ready-to-run evaluation board centered on the R5F565N7BDFB MCU. Unlike bare MCUs, it integrates debug circuitry, LCD, touch panel, Ethernet PHY, USB connector, and preloaded secure bootloader. The R5F565N7BDFB#30 delivers out-of-box firmware update capability and validated hardware-software integration unavailable with the R5F565N7BDFB MCU alone.
How does firmware update work on the R5F565N7BDFB#30?
Firmware update on the R5F565N7BDFB#30 uses a dual-bank flash architecture and RSU-formatted files. Users copy std.rsu or bench.rsu to a FAT32-formatted USB stick, insert it, and hold SW2 >3 seconds. The onboard bootloader validates the RSU signature, swaps banks, and resets - preserving the previous firmware as fallback. No external programmer is required for field updates.
What development tools are supported for the R5F565N7BDFB#30?
The R5F565N7BDFB#30 is supported by Renesas e2 studio IDE, CS+ (formerly CubeSuite+), and IAR Embedded Workbench. It includes prebuilt demo projects (standard and benchmark), secure boot loader source, and mot-to-rsu conversion tool (convert.exe). Debugging uses on-board JTAG/SWD via USB, eliminating need for external debug probes during initial development.
Does the R5F565N7BDFB#30 support secure boot, and how is it implemented?
Yes, the R5F565N7BDFB#30 implements secure boot using ROM-resident bootloader code that enforces cryptographic verification of RSU firmware images. Each RSU must be signed with a private key; the bootloader checks the signature using embedded public key and SHA-256/AES-128 before allowing bank swap. This prevents execution of tampered or unsigned firmware on the R5F565N7BDFB#30.
Can the R5F565N7BDFB#30 be used for production deployment?
The R5F565N7BDFB#30 is an evaluation kit intended for prototyping and firmware validation - not for volume production. However, its reference design, schematic, and layout files are publicly available, enabling direct reuse of validated subsystems (e.g., Ethernet PHY interface, touch controller routing, secure boot flow) in custom production boards based on the same R5F565N7BDFB MCU.
