Product details
Overview
R5F56517EDFB#30 from Renesas Electronics is a 32-bit RXv2 core MCU in LQFP-144 package, operating at up to 120 MHz with 2 MB flash, 384 KB RAM, and integrated USB 2.0 FS host/device, Ethernet MAC, and AES encryption engine - deployed as the main controller on the RX65N Envision Kit evaluation board.
For engineers reviewing the R5F56517EDFB#30 datasheet, R5F56517EDFB#30 pinout, R5F56517EDFB#30 application, or R5F56517EDFB#30 equivalent, key selection considerations include dual-bank flash architecture for secure firmware updates, hardware-based secure boot support, and integrated peripherals enabling rapid prototyping of industrial HMI and networked IoT edge nodes.
Technical Context
The R5F56517EDFB#30 implements Renesas' RXv2 CPU core with 2-stage pipeline, FPU, and 16-bit multiply-accumulate unit. It integrates a dedicated Secure Boot ROM and supports encrypted firmware loading via RSU files validated by SHA-256 and RSA-2048 signatures.
Firmware update operation relies on dual-bank flash (Bank A/B), bank-swap logic, and SW2-triggered 3-second hold for forced boot loader entry - enabling field-upgradable applications without external programming hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit, 120 MHz max - enables real-time deterministic execution for industrial control loops. |
| Flash Memory | 2 MB dual-bank flash - supports atomic firmware updates with zero-downtime bank swapping. |
| RAM | 384 KB SRAM - sufficient for concurrent Ethernet TCP/IP stack, USB device stack, and GUI frame buffer. |
| Secure Boot | Hardware ROM-based boot loader with SHA-256/RSA-2048 validation - enforces firmware authenticity before execution. |
| USB Interface | USB 2.0 Full-Speed host/device - enables direct connection to USB memory sticks for RSU firmware loading. |
| Ethernet | 10/100 Mbps MAC with RMII interface - provides wired network connectivity for remote firmware deployment and diagnostics. |

FAQ
What is the role of R5F56517EDFB#30 on the RX65N Envision Kit?
R5F56517EDFB#30 serves as the primary application processor on the RX65N Envision Kit, executing preloaded demo firmware (std.rsu or bench.rsu) and managing USB-based firmware updates, touch display I/O, Ethernet communication, and secure boot verification. Its dual-bank flash and hardware crypto engine directly enable the kit's bank-swap update workflow.
How does R5F56517EDFB#30 support secure firmware updates?
R5F56517EDFB#30 uses an immutable Secure Boot ROM to validate RSU firmware images using SHA-256 hash and RSA-2048 signature checks before loading into flash. The dual-bank architecture allows verified firmware to be written to the inactive bank, then activated via atomic bank swap - ensuring no invalid firmware ever executes.
Which interfaces on R5F56517EDFB#30 are used for firmware loading from USB memory stick?
R5F56517EDFB#30 uses its integrated USB 2.0 Full-Speed peripheral in device mode to enumerate as a mass storage device during boot loader mode, and in host mode to read *.rsu files from USB memory sticks. SW2 hold detection triggers entry into this USB-host firmware loading state.
Does R5F56517EDFB#30 require external circuitry for Ethernet connectivity on the Envision Kit?
No - R5F56517EDFB#30 integrates a full 10/100 Mbps Ethernet MAC with RMII interface. On the RX65N Envision Kit, it connects directly to the LAN8720A PHY via RMII signals and MDC/MDIO lines; no external MAC or bridge IC is required for basic Ethernet operation.
Can R5F56517EDFB#30 execute benchmark and standard demos simultaneously?
No - R5F56517EDFB#30 runs only one active firmware image at a time, stored in either Bank A or Bank B. The boot loader selects which bank to execute at reset; switching between standard and benchmark demos requires a bank-swap operation followed by software reset, as implemented in the RX65N Envision Kit's update flow.
