Connectivity and I/O — one MCU for sensor, actuator, and panel links
The EBI/EMI interface also allows expansion to external memory or an FPGA if the on-chip 256 KB Flash and 64 KB RAM are insufficient for the application.

Yes — the R5F566TABDFL#30 is part of the RX65N group within the RX series. It shares the same RXv3 core, 160 MHz clock, and peripheral set as other RX65N devices, so code and pin assignments are consistent across the family.
