For engineers reviewing the R5F563NFDDFB#V0 datasheet, R5F563NFDDFB#V0 pinout, R5F563NFDDFB#V0 application, or R5F563NFDDFB#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-A (144-pin LQFP, 20 × 20 mm, 0.5-mm pitch), functional differentiation from RX631 Group (Ethernet, SDRAM interface, RTC, PDC), and validated alternative options for migration or second sourcing.

Technical Context

The R5F563NFDDFB#V0 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. It integrates dedicated DMA controllers (DMAC, EXDMAC, DTC) and an Ethernet MAC with MII/RMII support, enabling concurrent high-throughput peripheral handling without CPU saturation.

Its memory subsystem includes zero-wait-state 100-MHz flash (2 MB), 256 KB SRAM, and 32 KB reprogrammable data flash (100,000 cycles). Clock management supports external crystal (4–16 MHz), internal HOCO/LOCO oscillators, and PLL-based system clock generation with independent domain scaling for ICLK (100 MHz), PCLK (50 MHz), FCLK (50 MHz), and BCLK (50 MHz).

FAQ

What is the maximum operating frequency and core performance of the R5F563NFDDFB#V0?

The R5F563NFDDFB#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using its 32-bit RX CPU core with single-precision IEEE-754 floating-point unit. Its 5-stage pipeline, variable-length instruction set, and on-chip multiplier/divider enable deterministic real-time execution critical for industrial control loops and protocol stacks. The R5F563NFDDFB#V0 achieves this performance within a 2.7–3.6 V supply range and -40 to +85°C operating temperature.

Does the R5F563NFDDFB#V0 include Ethernet functionality, and what interfaces does it support?

Yes, the R5F563NFDDFB#V0 includes a fully integrated Ethernet MAC compliant with IEEE 802.3 and 802.3u standards, supporting 10/100 Mbps operation in full- and half-duplex modes. It provides both MII and RMII physical layer interfaces, Magic Packet™ wake-on-LAN detection, and IEEE 802.3x flow control. The dedicated EDMAC controller with 2 KB TX/RX FIFOs enables zero-copy packet handling - a key capability distinguishing the R5F563NFDDFB#V0 from RX631 Group devices.

What memory resources are available on the R5F563NFDDFB#V0, and how are they configured?

The R5F563NFDDFB#V0 integrates 2 MB of on-chip flash memory (executed at 100 MHz with zero wait states), 256 KB of SRAM (also zero-wait at 100 MHz), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. Flash supports on-board programming via SWD/FINE and off-board parallel programming. SRAM is unified for instructions and data and supports deep software standby backup. These resources are fixed for the R5F563NFDDFB#V0 and do not require external memory expansion for most industrial gateway implementations.

How does the R5F563NFDDFB#V0 differ from other RX63N variants like R5F563NFHDFB#V0 or R5F563NECDFB#V0?

The R5F563NFDDFB#V0 shares the same 144-pin LQFP package and 2 MB flash capacity with R5F563NFHDFB#V0 and R5F563NECDFB#V0, but differs in SRAM size and peripheral inclusion. R5F563NFDDFB#V0 has 256 KB SRAM and excludes SDRAM controller and PDC - unlike R5F563NFHDFB#V0 - while R5F563NECDFB#V0 has only 128 KB SRAM. All three retain identical Ethernet, USB, CAN, and analog peripherals, making R5F563NFDDFB#V0 the optimal choice when 256 KB SRAM is required without SDRAM dependency.

What security and reliability features are implemented in the R5F563NFDDFB#V0 for industrial use?

The R5F563NFDDFB#V0 includes hardware-accelerated AES-128/192/256 encryption (ECB/CBC modes) via its Data Encryption Unit (DEU), a tamper-resistant RTC with battery backup, independent watchdog timer (IWDT) driven by a dedicated LOCO oscillator, and memory protection unit (MPU) for runtime privilege enforcement. It also supports IEC 60730 Class B compliance functions including oscillation-stoppage detection, CRC calculation, and A/D self-diagnostic routines - all confirmed in the R5F563NFDDFB#V0's certified device configuration.
