FAQ

What is the maximum operating frequency and core architecture of the R5F563NBDGFB#V0?

The R5F563NBDGFB#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 includes a single-precision IEEE-754 floating-point unit for deterministic math-intensive tasks in industrial control firmware.

Does the R5F563NBDGFB#V0 support Ethernet connectivity, and what interface options are available?

Yes, the R5F563NBDGFB#V0 integrates a full-featured Ethernet MAC supporting both 10 and 100 Mbps operation in full- and half-duplex modes. It supports IEEE 802.3u-compliant MII and RMII physical layer interfaces, along with Wake-on-LAN via Magic Packet detection and IEEE 802.3x flow control - enabling compact, low-component-count networked designs without external PHY ICs.

What analog peripherals are included in the R5F563NBDGFB#V0, and what are their key specifications?

The R5F563NBDGFB#V0 includes a 21-channel 12-bit successive-approximation ADC (S12ADa) with 1 µs conversion time at 50 MHz PCLK and integrated sample-and-hold, an 8-channel 10-bit ADC (ADb), two 10-bit DACs (DAa), and an on-die temperature sensor accurate to ±1°C. These enable high-fidelity sensor interfacing and closed-loop analog control without external signal conditioning.

Is the R5F563NBDGFB#V0 pin-compatible with other members of the RX63N Group, and what package does it use?
