FAQ

What is the maximum operating frequency and CPU architecture of the R5F565N4EDFB#10?

The R5F565N4EDFB#10 operates at a maximum frequency of 120 MHz and uses the 32-bit RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit. This architecture enables high code density and deterministic real-time execution essential for industrial control applications running on the R5F565N4EDFB#10.

Does the R5F565N4EDFB#10 support dual-bank flash and background programming?

Yes, the R5F565N4EDFB#10 features 2 MB of on-chip code flash memory organized in a dual-bank structure, enabling background programming (BGO) and safe bank switching during runtime. This allows firmware updates without interrupting application execution-a critical capability for field-deployed systems requiring zero-downtime maintenance. The R5F565N4EDFB#10 supports simultaneous read-from-one-bank and write-to-the-other-bank operations, verified in Renesas' R01DS0276EJ0240 datasheet.

What graphics and display interfaces does the R5F565N4EDFB#10 integrate?

The R5F565N4EDFB#10 integrates a full-featured Graphic-LCD Controller (GLCDC) supporting 24-bit RGB parallel output (GLCD_D0–23), HSYNC/VSYNC/DE synchronization, and 3-plane overlay (background, graphic 1, graphic 2). It also includes a dedicated 2D Drawing Engine (DRW2D) for hardware-accelerated vector drawing, bit blitting, and texture mapping. These peripherals eliminate the need for external graphics controllers in HMI applications built around the R5F565N4EDFB#10.

How does the R5F565N4EDFB#10 meet IEC 60730 Class B safety requirements?

The R5F565N4EDFB#10 includes multiple hardware safety features certified for IEC 60730 Class B: oscillation-stop detection, CRC calculator (CRCA) with configurable polynomials, independent watchdog timer (IWDT) with windowing, register write protection, and A/D converter self-diagnostic function. These features-documented in the R01DS0276EJ0240 datasheet-are implemented in silicon and require no software overhead, making the R5F565N4EDFB#10 suitable for safety-critical industrial control and appliance applications.

What is the package type and pin count of the R5F565N4EDFB#10?

The R5F565N4EDFB#10 is housed in a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) package designated PLQP0176KB-A, measuring 24 mm × 24 mm with 0.5 mm ball pitch. It provides 136 general-purpose I/O pins (5-V tolerant on 19 pins), along with dedicated signals for Ethernet, CAN, SD, QSPI, GLCDC, and USB. This package is explicitly confirmed for the R5F565N4EDFB#10 in Renesas' official documentation and ordering information.
