Product details

Overview

R5F56514FDLJ#20 from Renesas Electronics is an RX65N Group 32-bit microcontroller evaluation platform controller IC used in the RX65N Envision Kit development board, featuring 100-pin LQFP packaging, 1 MB flash memory, 128 KB RAM, and integrated USB host/device interface for firmware update via USB memory stick. It enables secure boot, dual-bank firmware swapping, and touch display control in industrial HMI applications.

For engineers reviewing the R5F56514FDLJ#20 datasheet, R5F56514FDLJ#20 pinout, R5F56514FDLJ#20 application, or R5F56514FDLJ#20 equivalent, key selection criteria include dual-bank RSU firmware update capability, secure boot loader support, USB-based field update workflow, and compatibility with RX65N Envision Kit hardware revision FDLJ.

Technical Context

The R5F56514FDLJ#20 implements the RXv2 CPU core with FPU and DSP extensions, operating at up to 120 MHz. It integrates a dedicated secure boot ROM, flash memory with ECC protection, and a hardware AES engine for encrypted firmware validation prior to bank swap.

Firmware updates are managed through a two-stage process: first, *.rsu files (converted from *.mot using convert.exe) are loaded from USB mass storage; second, the boot loader validates signature integrity, performs CRC check, and executes atomic bank swap with software reset-ensuring zero-downtime field updates.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	RXv2 32-bit with FPU and DSP instructions, enabling real-time math-intensive HMI and control tasks
Max Clock Speed	120 MHz - supports high-throughput USB communication and fast touch response rendering
Flash Memory	1 MB with ECC and dual-bank architecture - allows safe over-the-air firmware updates without system interruption
RAM	128 KB SRAM - sufficient for concurrent execution of bootloader, active firmware, and UI frame buffer
USB Interface	Full-speed USB 2.0 host/device controller - enables direct firmware loading from USB memory stick without PC dependency
Secure Boot	Hardware-verified boot from on-chip ROM - enforces cryptographic signature validation before executing user firmware

FAQ

What is the role of R5F56514FDLJ#20 in the RX65N Envision Kit?

R5F56514FDLJ#20 serves as the main MCU on the RX65N Envision Kit evaluation board, executing both the secure boot loader and user demo firmware (standard or benchmark). It manages USB-based firmware loading, dual-bank swapping, touch display interaction, and peripheral initialization per the kit's reference design.

How does R5F56514FDLJ#20 support firmware updates?

R5F56514FDLJ#20 supports field firmware updates via USB memory stick using *.rsu files. The onboard boot loader validates digital signatures and CRCs, then performs atomic bank swap between primary and secondary flash banks-ensuring fail-safe operation without bricking the device during update.

Is R5F56514FDLJ#20 pin-compatible with other RX65N MCUs?

R5F56514FDLJ#20 uses a 100-pin LQFP package matching the RX65N Group's standard pinout. While functionally aligned with other RX65N variants like R5F5651EDFP#30, pin compatibility requires verification against individual variant datasheets due to peripheral mapping differences across memory sizes and feature sets.

What development tools are required for R5F56514FDLJ#20?

Development for R5F56514FDLJ#20 requires Renesas e2 studio IDE, CS+ compiler, and the RX65N Envision Kit hardware. Firmware conversion uses convert.exe (provided in rx65n_envisionkit.zip) to generate *.rsu files from *.mot outputs, enabling USB-based deployment without JTAG debuggers.

Does R5F56514FDLJ#20 support touch screen interfaces?

Yes, R5F56514FDLJ#20 integrates a capacitive touch sensing unit (CTSU) compatible with the RX65N Envision Kit's 4.3-inch resistive touch display. The standard demo firmware demonstrates touch-driven navigation, confirming full CTSU driver and interrupt handling support out-of-box.
