FAQ

What is the maximum operating frequency and core type of the R5F563NEDDBG#U0?

The R5F563NEDDBG#U0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core. This core delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, 5-stage pipeline, and variable-length instruction set optimized for code density and real-time responsiveness. Its architecture supports deterministic interrupt latency critical for industrial control loops.

Does the R5F563NEDDBG#U0 include an Ethernet MAC, and what standards does it support?

Yes, the R5F563NEDDBG#U0 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 and RMII physical layer interfaces, Magic Packet™ wake-on-LAN detection, and IEEE 802.3x flow control. This eliminates the need for an external Ethernet PHY in many industrial gateway designs.

What memory resources are available on the R5F563NEDDBG#U0?

The R5F563NEDDBG#U0 provides 2 Mbytes of on-chip flash memory with zero-wait-state access at 100 MHz, 128 Kbytes of high-speed SRAM, and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. The flash supports background programming/erasing (BGO), enabling firmware updates without halting application execution-essential for secure OTA deployments.

How does the R5F563NEDDBG#U0 support functional safety standards like IEC 60730?

The R5F563NEDDBG#U0 includes multiple hardware features for IEC 60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculator (with three polynomials), independent watchdog timer (IWDT) with dedicated LOCO clock, self-diagnostic A/D converter test mode, and memory protection unit (MPU) for runtime memory access enforcement-all documented in Renesas' functional safety manual R01US0076EJ0200.

What package type and pin count does the R5F563NEDDBG#U0 use?

The R5F563NEDDBG#U0 uses the PLBG0176GA-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 13 × 13 mm with 0.8 mm ball pitch. This LFBGA package provides superior thermal dissipation and mechanical stability compared to QFP alternatives, making it ideal for industrial environments subject to thermal cycling and vibration.
