Technical Context

The R5F563NEDDBG#G0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and MPU support. Its clock system integrates PLL, HOCO (50 MHz), LOCO (125 kHz), and subclock oscillators, enabling independent domain clocking (ICLK up to 100 MHz, PCLK up to 50 MHz).

It includes dedicated hardware accelerators: EDMAC for zero-CPU-load Ethernet packet handling (2 KB TX/RX FIFO), DEU for AES-128/192/256 encryption/decryption, and DTC/DMAC/EXDMAC for parallel peripheral-to-memory transfers - critical for real-time sensor fusion and protocol stack offload in gateway applications.

FAQ

What is the maximum operating frequency and core architecture of the R5F563NEDDBG#G0?

The R5F563NEDDBG#G0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit. This architecture enables deterministic real-time execution critical for industrial control loops and protocol stack processing in the R5F563NEDDBG#G0.

Does the R5F563NEDDBG#G0 support Ethernet connectivity, and what interface standards does it implement?

Yes, the R5F563NEDDBG#G0 integrates a full IEEE 802.3-compliant Ethernet MAC supporting both 10 Mbps and 100 Mbps operation in full- and half-duplex modes. It implements MII and RMII physical layer interfaces and includes Magic Packet™ wake-on-LAN detection. The dedicated EDMAC hardware handles descriptor-based frame transfers, minimizing CPU overhead during sustained Ethernet traffic - a defining feature distinguishing the R5F563NEDDBG#G0 from non-Ethernet RX631 variants.

What security and functional safety features are built into the R5F563NEDDBG#G0?

The R5F563NEDDBG#G0 includes a hardware Data Encryption Unit (DEU) supporting AES-128/192/256 in ECB and CBC modes, CRC calculation with three configurable polynomials, independent watchdog timer (IWDT) with dedicated oscillator, oscillation-stoppage detection, and A/D converter self-diagnostic functions. These features collectively support IEC60730 Class B compliance, enabling R5F563NEDDBG#G0-based designs to meet industrial safety certification requirements without external safety monitors.

What is the package type and pin count of the R5F563NEDDBG#G0, and how does it compare to other RX63N variants?

The R5F563NEDDBG#G0 uses a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) package designated PLBG0176GA-A, measuring 13 × 13 mm with 0.8 mm ball pitch. This matches the pinout of other 176-pin RX63N variants like R5F563NECDDBG#G0 but differs from 177-pin TFLGA or 144-pin LQFP versions. The 176-pin LFBGA provides 133 general-purpose I/Os with 5-V tolerance on 18 pins - a key mechanical and routing constraint for R5F563NEDDBG#G0 PCB layout.

How much on-chip memory does the R5F563NEDDBG#G0 provide, and what are its access characteristics?

The R5F563NEDDBG#G0 integrates 2 Mbytes of on-chip flash memory with 100 MHz no-wait-state access, 128 Kbytes of SRAM also with no-wait access, and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. Flash supports background programming/erasing (BGO), enabling firmware updates without halting application execution. These memory resources are fully utilized in the R5F563NEDDBG#G0 to host real-time OS, protocol stacks, and application code within a single-chip solution.
