It features 1 MB on-chip flash, 128 KB SRAM, 32 KB data flash, and operates from 2.7–3.6 V across –40 to +85°C. Used in industrial gateways requiring real-time control, networked sensing, and secure firmware updates.

For engineers reviewing the R5F563NBDGFC#V0 datasheet, R5F563NBDGFC#V0 pinout, R5F563NBDGFC#V0 application, or R5F563NBDGFC#V0 equivalent, key selection criteria include Ethernet MAC support, 100 MHz deterministic timing, IEEE 802.3-compliant RMII/MII interface, 128 KB zero-wait-state SRAM for real-time buffering, and IEC60730 safety features including CRC, self-diagnostic A/D, and oscillation-stop detection.

Technical Context

The R5F563NBDGFC#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dedicated DMA controllers - DMAC (4 ch), EXDMAC (2 ch), and EDMAC (1 ch for Ethernet) - to offload CPU bandwidth during high-throughput peripheral transfers.

Its clock system supports independent domain scaling: ICLK up to 100 MHz for CPU execution, PCLK up to 50 MHz for peripherals, FCLK/BCLK at 50 MHz for flash and external bus, and IWDT-dedicated 125 kHz LOCO. The MPU enforces memory protection, while FPU provides IEEE-754 single-precision floating-point operations at 165 DMIPS.

FAQ

What is the maximum operating frequency and core type of the R5F563NBDGFC#V0?

The R5F563NBDGFC#V0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core. This core delivers 165 DMIPS performance with a 5-stage pipeline, IEEE-754 single-precision FPU, and ultra-compact variable-length instruction set. Its deterministic timing and low-latency interrupt response make it suitable for hard real-time industrial control tasks where R5F563NBDGFC#V0 must meet sub-microsecond jitter requirements.

Does the R5F563NBDGFC#V0 support Ethernet connectivity, and what interface modes are available?

Yes, the R5F563NBDGFC#V0 integrates a full IEEE 802.3-compliant Ethernet MAC supporting both 10 and 100 Mbps operation in full- and half-duplex modes. It supports MII (Media Independent Interface) and RMII (Reduced MII) physical layer interfaces, with dedicated pins for ETH_MDC/MDIO management and ETH_TXD[3:0]/RXD[3:0] data lanes. The R5F563NBDGFC#V0 also includes an EDMAC controller to handle descriptor-based packet transfers independently of the CPU.

What are the memory resources available on the R5F563NBDGFC#V0?

The R5F563NBDGFC#V0 includes 1 MB of on-chip flash memory (accessible at 100 MHz with zero wait states), 128 KB of zero-wait-state SRAM for instruction and data, and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. These memory resources are tightly coupled to the RXv1 core and support background programming/erasing, enabling robust firmware updates and parameter storage without halting application execution on R5F563NBDGFC#V0.

Which communication interfaces does the R5F563NBDGFC#V0 support besides Ethernet?

Besides Ethernet, the R5F563NBDGFC#V0 supports USB 2.0 full-speed host/function/OTG (with integrated transceiver), three CAN 2.0B channels (32 mailboxes each), thirteen SCI channels (asynchronous, SPI/I²C emulation, LIN), four I²C interfaces (one FM+ capable at 1 Mbps), three RSPI ports, one IEBus channel, and a parallel data capture unit (PDC). This breadth enables R5F563NBDGFC#V0 to serve as a multi-protocol convergence hub in complex industrial systems.

Is the R5F563NBDGFC#V0 qualified for functional safety standards such as IEC60730?

Yes, the R5F563NBDGFC#V0 includes hardware features specifically designed for IEC60730 Class B compliance: oscillation-stoppage detection, clock frequency measurement, CRC calculator (with three polynomial options), independent watchdog timer (IWDT), and self-diagnostic capability for the 10-bit A/D converter. These features are documented in the R01DS0098EJ0180 datasheet and enable certified safety firmware implementation without external components - a key requirement for R5F563NBDGFC#V0 in white goods and industrial controls.
