It supports CAN (3 channels), USB 2.0 FS host/function, SDHI, QSPI, and GLCDC - deployed in industrial HMIs, networked PLCs, and real-time motion controllers.

For engineers reviewing the R5F572NNHDFP#30 datasheet, R5F572NNHDFP#30 pinout, R5F572NNHDFP#30 application, or R5F572NNHDFP#30 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-bank flash for safe firmware updates, 182 GPIO with 5-V tolerance, ECC-protected RAM for IEC 60730 Class B compliance, and hardware-accelerated trigonometric (TFU) and AES encryption functions.

Technical Context

The R5F572NNHDFP#30 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (16×64-bit data registers), and collective register bank save for fast context switching. Its clock system integrates PLLs, HOCO/LOCO oscillators, and independent PCLK domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz) enabling precise peripheral timing isolation.

It features three DMA subsystems - DMACAa (8 channels), EXDMAC (2 channels), and DTCb (1 channel) - coordinated via Event Link Controller (ELC) for zero-CPU-intervention peripheral chaining. The memory subsystem includes 2 MB code flash with ROM cache, 32 KB data flash (100k erase cycles), 32 KB ECC RAM (SEC-DED), and 8 KB standby RAM backed by VBATT.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572NNHDFP#30?

The R5F572NNHDFP#30 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's efficient pipeline, double-precision FPU, and zero-wait-state access to on-chip SRAM and flash cache - enabling real-time deterministic execution in demanding industrial control loops.

Does the R5F572NNHDFP#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NNHDFP#30 includes dedicated hardware in its EPTPC module for IEEE 1588-2008 (PTPv2) timestamping, with nanosecond-resolution capture on both transmit and receive paths. When paired with the dual-channel ETHERC, the R5F572NNHDFP#30 achieves sub-100 ns time synchronization accuracy - essential for PROFINET IRT and EtherCAT master applications.

What safety certifications or features does the R5F572NNHDFP#30 provide for industrial use?

The R5F572NNHDFP#30 includes multiple IEC 60730 Class B compliance features: oscillation-stop detection, CRC accelerator, self-diagnostic A/D test, register write protection, IWDT with windowing, and 32 KB ECC RAM with SEC-DED error correction. These are documented in Renesas' Functional Safety Manual R01UM0127EJ0200 and enable streamlined certification for safety-critical industrial equipment.

What is the flash memory configuration of the R5F572NNHDFP#30, and does it support background programming?

The R5F572NNHDFP#30 integrates 2 MB of on-chip code flash memory organized in a dual-bank structure, plus 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. Both support background programming (BGO), allowing code execution from one bank while the other is erased or programmed - a key enabler for fail-safe firmware updates in the R5F572NNHDFP#30.

Which graphics and display interfaces are supported by the R5F572NNHDFP#30?

The R5F572NNHDFP#30 integrates a full-featured Graphic-LCD Controller (GLCDC) supporting parallel RGB (up to 18-bit), ITU-R BT.601/656 video input via PDC, and hardware-accelerated 2D drawing (DRW2D). It drives resolutions up to WXGA (1280×800) with alpha blending and layer composition - eliminating need for external display controllers in industrial HMI designs using the R5F572NNHDFP#30.
