Product details
Overview
R5F56517ADLJ#20 from Renesas Electronics is a 32-bit RXv2 core microcontroller unit (MCU) with 1 MB flash, 192 KB RAM, and integrated USB 2.0 FS host/device controller, used in industrial HMI and secure boot reference designs on the RX65N Envision Kit platform.
For engineers reviewing the R5F56517ADLJ#20 datasheet, R5F56517ADLJ#20 pinout, R5F56517ADLJ#20 application, or R5F56517ADLJ#20 equivalent, this MCU serves as the main application processor in Renesas' RX65N Envision Kit firmware execution, dual-bank secure update, and touch-enabled demo deployment - requiring precise flash layout, bank-swapping timing, and USB-based firmware delivery support.
Technical Context
The R5F56517ADLJ#20 implements the RXv2 CPU core with 200 MHz max operation, supports dual-bank flash architecture for seamless firmware updates, and integrates a hardware AES-128 engine for secure boot verification of *.rsu images loaded via USB memory stick.
It features a 16-channel event link controller (ELC), 12-bit ADC with 24 channels, and a full-speed USB 2.0 interface configured in the RX65N Envision Kit to handle both host-mode USB mass storage enumeration and device-mode firmware download triggers.
Key Specifications

FAQ
What is the role of R5F56517ADLJ#20 in the RX65N Envision Kit?
The R5F56517ADLJ#20 serves as the primary application MCU on the RX65N Envision Kit, executing standard and benchmark demo firmware, managing dual-bank flash swaps, and handling USB-based firmware updates. Its integrated peripherals - including USB FS, AES engine, and ELC - directly enable the kit's secure boot flow and touch-driven user interaction as documented in Renesas' firmware update guides.
Does R5F56517ADLJ#20 support secure firmware updates?
Yes, R5F56517ADLJ#20 supports secure firmware updates through its hardware AES-128 engine and true random number generator (TRNG), which verify signed *.rsu firmware images before programming. The bootloader uses these features to enforce authenticated firmware installation, preventing unauthorized code execution - a core capability demonstrated in the RX65N Envision Kit's std.rsu and bench.rsu update process.
What package type does R5F56517ADLJ#20 use?
R5F56517ADLJ#20 is housed in a 145-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), matching the physical footprint and thermal profile required for the RX65N Envision Kit's PCB layout. This package provides full access to all I/Os needed for USB, touch display, SD card, and Ethernet interfaces on the evaluation board.
How is R5F56517ADLJ#20 configured for USB firmware updates?
R5F56517ADLJ#20 is configured in USB device mode to enumerate as a mass storage class (MSC) device when SW1-1 is ON during power-on reset, allowing direct access to its internal flash banks. In normal operation, it runs in USB host mode to read *.rsu files from an attached USB memory stick - a dual-role configuration enabled by its integrated USB 2.0 FS controller and verified in the RX65N Envision Kit firmware flow.
Can R5F56517ADLJ#20 execute both standard and benchmark demos simultaneously?
No, R5F56517ADLJ#20 executes only one demo firmware image at a time - either the standard demo (std.rsu) or benchmark demo (bench.rsu) - stored in separate flash banks. Bank swapping is triggered manually via SW2 hold or programmatically via USB command, ensuring deterministic runtime behavior and isolation between functional test modes as implemented in the RX65N Envision Kit firmware architecture.
