FAQ

What is the maximum operating frequency and CPU architecture of the R5F565N4BDFB#10?

The R5F565N4BDFB#10 operates at a maximum system clock frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. Its performance is rated at 240 DMIPS, and it includes a single-precision IEEE-754 floating-point unit. The R5F565N4BDFB#10 achieves this speed with zero wait states for flash access up to 50 MHz and one wait state up to 100 MHz when cache hits occur.

Does the R5F565N4BDFB#10 support dual-bank flash and background programming?

Yes, the R5F565N4BDFB#10 supports dual-bank flash architecture with 2 MB of on-chip code flash memory, enabling background programming (BGO) and safe firmware updates. This allows the R5F565N4BDFB#10 to execute code from one bank while programming or erasing the other, ensuring uninterrupted real-time operation-a critical feature for industrial gateways and medical devices requiring zero-downtime updates.

What graphics and display capabilities does the R5F565N4BDFB#10 provide?

The R5F565N4BDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting 3-plane overlay (background, graphic 1, graphic 2) and a 2D Drawing Engine (DRW2D) for vector drawing, bit blitting, rotation, and texture mapping. It supports 32-/16-bpp graphics and CLUT formats, enabling rich HMI rendering without external graphics ICs. These features make the R5F565N4BDFB#10 ideal for standalone industrial panels with TFT-LCD displays.

How does the R5F565N4BDFB#10 meet IEC60730 functional safety requirements?

The R5F565N4BDFB#10 includes multiple hardware features certified for Class B compliance: oscillation-stop detection, CRC calculator (CRCA), independent watchdog timer (IWDT) with configurable window, self-diagnostic A/D converter, and register write protection. These functions allow the R5F565N4BDFB#10 to detect and respond to faults autonomously-essential for household appliances, motor controls, and medical equipment requiring safety certification.

What is the package type and pin count of the R5F565N4BDFB#10?

The R5F565N4BDFB#10 uses the PLQP0176KB-A package: a 176-pin Low-Profile Quad Flat Package measuring 24 × 24 mm with 0.5-mm pitch. It provides 136 general-purpose I/O pins-including 19 with 5-V tolerance-and supports multiple low-power modes. This package is optimized for high-density industrial PCB layouts requiring robust thermal and electrical performance.
