FAQ

What is the maximum operating frequency and core architecture of the R5F563NWDDFC#V0?

The R5F563NWDDFC#V0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core - a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU). It delivers 165 DMIPS and supports IEEE-754 single-precision floating-point operations. This architecture enables deterministic real-time performance critical for industrial control and protocol stack execution in the R5F563NWDDFC#V0.

Does the R5F563NWDDFC#V0 include an Ethernet MAC, and what interface standards does it support?

Yes, the R5F563NWDDFC#V0 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 (Media Independent Interface) and RMII (Reduced MII) as defined in IEEE 802.3u, includes Magic Packet detection for wake-on-LAN, and supports IEEE 802.3x flow control. These capabilities are native to the R5F563NWDDFC#V0 and require no external PHY logic beyond standard magnetics.

What are the memory resources available on the R5F563NWDDFC#V0?

The R5F563NWDDFC#V0 includes 1 Mbyte of on-chip flash memory (zero-wait-state at 100 MHz), 192 Kbytes of on-chip SRAM (zero-wait-state), and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. The SRAM is unified for instructions and data and supports deep software standby backup. These memory resources are fixed for the R5F563NWDDFC#V0 and enable concurrent execution of Ethernet, USB, and CAN protocol stacks without external memory.

Which communication interfaces are integrated into the R5F563NWDDFC#V0?

The R5F563NWDDFC#V0 integrates Ethernet MAC, USB 2.0 host/function/OTG, three CAN 2.0B channels, thirteen SCI channels (including LIN support), four I2C interfaces (one FM+), three RSPI channels, one IEBus channel, and one parallel data capture unit (PDC). All are silicon-native features of the R5F563NWDDFC#V0 - no external bridge ICs are required to implement this multi-protocol interface set.

Does the R5F563NWDDFC#V0 support functional safety standards such as IEC60730?

Yes, the R5F563NWDDFC#V0 includes hardware features specifically targeting IEC60730 Class B compliance: oscillation-stop detection, clock frequency measurement, CRC calculator (with three polynomials), independent watchdog timer (IWDT) with dedicated oscillator, and self-diagnostic capability for the 10-bit A/D converter. These are implemented in silicon and documented in the R5F563NWDDFC#V0 hardware manual as part of its safety support framework.
