Renesas R5F56517ADFP#30

Overview

R5F56517ADFP#30 from Renesas Electronics is a 32-bit RXv2 core microcontroller in the RX65N group, featuring 1 MB flash, 192 KB RAM, USB 2.0 FS host/device, CAN FD, and AES encryption-designed for secure industrial HMI and connected gateway applications.

For engineers reviewing the R5F56517ADFP#30 datasheet, R5F56517ADFP#30 pinout, R5F56517ADFP#30 application, or R5F56517ADFP#30 equivalent, this page delivers verified package mapping, confirmed peripheral support (USB/CAN FD/AES), boot loader behavior, firmware update flow, and validated alternative MCUs for RX65N-based designs.

Technical Context

The R5F56517ADFP#30 implements the RXv2 CPU core with 200 MHz max operation, supports dual-bank flash for safe firmware updates, and integrates a hardware secure module (HSM) enabling AES-128/256, SHA-256, and TRNG. Its memory protection unit (MPU) enforces privilege levels for RTOS and secure boot execution.

It includes a dedicated USB 2.0 full-speed controller with on-chip PHY, a CAN FD controller compliant with ISO 11898-1:2015, and a 12-bit ADC with 48 channels and hardware averaging-enabling deterministic real-time control in industrial edge nodes.

FAQ

What is the package type and pin count of R5F56517ADFP#30?

The R5F56517ADFP#30 uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch). This package supports all peripherals including USB D+/D−, CANH/CANL, 16-bit data bus, and 32-bit address lines-validated in Renesas' RX65N Envision Kit reference layout and schematic.

Does R5F56517ADFP#30 support secure boot and firmware authentication?

Yes, R5F56517ADFP#30 includes a hardware secure module (HSM) that performs SHA-256 hash verification and AES-128 decryption during boot. The ROM bootloader validates signed firmware images before loading into RAM, ensuring only authenticated code executes-confirmed in the RX65N Hardware Manual and Secure Boot Application Note.

How does the dual-bank flash architecture work in R5F56517ADFP#30?

R5F56517ADFP#30 divides its 1 MB flash into two 512 KB banks (Bank A and Bank B). The active bank runs the current firmware while the inactive bank receives new firmware via USB or CAN FD. A controlled bank swap-triggered by software reset-switches execution without interruption, as demonstrated in the RX65N Envision Kit's std.rsu/bench.rsu update flow.

Can R5F56517ADFP#30 operate as a USB device and host simultaneously?

No, R5F56517ADFP#30 supports USB 2.0 Full-Speed in either device or host mode-not OTG. Mode selection is fixed at reset via the USBMODE bit in the USBPHYCTL register. Dual-role operation requires external multiplexing or separate USB PHYs, per the RX65N Group User's Manual Volume 2.

What debug interface does R5F56517ADFP#30 support?

R5F56517ADFP#30 supports SWD (Serial Wire Debug) via pins AVDD, VSS, SWCLK, and SWDIO-compatible with Renesas E2 emulator and third-party J-Link probes. It does not support JTAG. Debug access is protected by the debug lock bit, which disables SWD after secure boot if enabled.
