FAQ

What is the primary function of the R5F565NCDDFB#30?

The R5F565NCDDFB#30 is an evaluation board, not a standalone IC. It integrates the RX65N microcontroller to demonstrate secure boot, dual-bank firmware updates, capacitive touch, and LCD graphics capabilities. Engineers use the R5F565NCDDFB#30 to validate application code, evaluate peripheral performance, and prototype HMI designs before custom PCB development.

How does firmware update work on the R5F565NCDDFB#30?

Firmware updates on the R5F565NCDDFB#30 are performed by inserting a USB memory stick containing *.rsu files (e.g., std.rsu or bench.rsu) and selecting the file via the bootloader menu. The R5F565NCDDFB#30 then validates the signature, swaps active/inactive flash banks, and performs a software reset - ensuring zero-downtime updates with rollback capability.

Does the R5F565NCDDFB#30 support secure boot, and how is it implemented?

Yes, the R5F565NCDDFB#30 supports hardware-enforced secure boot using the RX65N's on-chip AES-128 engine and TRNG. During power-on reset, the bootloader verifies digital signatures of *.rsu firmware images loaded from USB. Only cryptographically authenticated firmware is executed - a core security feature validated in the R5F565NCDDFB#30's reference design and firmware release notes.

What display resolution and interface does the R5F565NCDDFB#30 support?

The R5F565NCDDFB#30 includes a 4.3-inch WVGA LCD panel with 480×272 resolution driven by the RX65N's native 16-bit RGB parallel interface. No external display controller is required - the R5F565NCDDFB#30 uses the MCU's integrated LCD controller to manage timing, pixel data, and backlight control directly.

Can the R5F565NCDDFB#30 be used for capacitive touch development?

Yes, the R5F565NCDDFB#30 integrates the RX65N's Capacitive Touch Sensing Unit (CTSU) with 10 channels and onboard electrodes. It supports proximity and touch detection through the front overlay glass, and sample projects in the rx65n_envisionkit.zip package provide calibrated CTSU drivers - making the R5F565NCDDFB#30 suitable for touch UI development without additional components.
