For engineers reviewing the R5F563NBDDFC#V0 datasheet, R5F563NBDDFC#V0 pinout, R5F563NBDDFC#V0 application, or R5F563NBDDFC#V0 equivalent, key selection criteria include Ethernet MAC support (vs. RX631), 100-MHz timing-critical peripheral operation, 12-bit/10-bit ADC channel count, USB 2.0 host/function/OTG capability, and LQFP-176 package compatibility with existing PCB layouts.

Technical Context

The R5F563NBDDFC#V0 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 165 DMIPS at 100 MHz. Its memory subsystem includes zero-wait-state 100-MHz flash, 100-MHz SRAM, and background-programmable 32-Kbyte data flash supporting 100,000 erase/write cycles.

Peripheral integration centers on deterministic real-time I/O: dual DMA controllers (DMAC + EXDMAC), Ethernet MAC with MII/RMII, three CAN modules (ISO 11898-1 compliant), 13 SCI channels with flexible protocol modes, and parallel data capture (PDC) for image sensor interfacing-all synchronized to independent clock domains (ICLK/PCLK/FCLK/BCLK).

FAQ

What is the maximum operating frequency and core performance of the R5F563NBDDFC#V0?

The R5F563NBDDFC#V0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core, delivering 165 DMIPS. It includes a single-precision IEEE-754 floating-point unit and hardware multiplier/divider-enabling efficient signal processing and control loop execution in real-time industrial applications. The R5F563NBDDFC#V0 achieves this performance with zero-wait-state access to both flash and SRAM.

Does the R5F563NBDDFC#V0 support Ethernet connectivity, and what interfaces are available?

Yes, the R5F563NBDDFC#V0 integrates a full-featured Ethernet MAC compliant with IEEE 802.3 and 802.3u standards, supporting 10/100 Mbps operation in full- and half-duplex modes. It supports both MII and RMII physical layer interfaces, Magic Packet™ wake-on-LAN, and IEEE 802.3x flow control. The dedicated EDMAC handles descriptor-based packet transfers independently of the CPU. The R5F563NBDDFC#V0 does not include a PHY; external magnetics and PHY IC are required.

What are the memory resources available on the R5F563NBDDFC#V0?

The R5F563NBDDFC#V0 includes 1 Mbyte of on-chip flash memory (accessible at 100 MHz with no wait states), 128 Kbytes of SRAM (also zero-wait-state), and 32 Kbytes of data flash rated for 100,000 program/erase cycles. The data flash supports background operation (BGO), allowing concurrent code execution and non-volatile parameter storage. The R5F563NBDDFC#V0 does not support external ROM or off-chip flash boot modes.

How many analog-to-digital converter channels does the R5F563NBDDFC#V0 provide, and what are their specifications?

The R5F563NBDDFC#V0 integrates two independent ADC units: a 12-bit S12AD with up to 21 input channels (1 µs conversion time at 50 MHz PCLK) and a 10-bit AD with up to 8 channels (also 1 µs). Both include sample-and-hold circuits, software/triggered start modes, and support for temperature sensor measurement. The R5F563NBDDFC#V0 does not include a 16-bit ADC or sigma-delta architecture.

Is the R5F563NBDDFC#V0 pin-compatible with other members of the RX63N Group?

Yes, the R5F563NBDDFC#V0 is pin-compatible with all other RX63N Group devices in the PLQP0176KB-A (LQFP-176) package, including R5F563NECDFC#V0, R5F563NEDDFC#V0, and R5F563NKDDFC#V0. Pin functions, power domains, and peripheral mappings are consistent across this package variant-enabling hardware reuse and scalable firmware development. The R5F563NBDDFC#V0 is not pin-compatible with RX631 Group parts or different packages like LQFP-144.
