Technical Context

The R5F572NNDDFB#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 memory subsystem includes 4 Mbytes of dual-bank code flash (enabling background programming and bank swap), 32 Kbytes of reprogrammable data flash (100,000 erase cycles), and ECC-protected 32 Kbytes RAM for safety-critical code execution.

Real-time capability is reinforced by 29 timers-including GPTW (32-bit ×4), MTU3a (16/32-bit ×9), and TPUa (16-bit ×6)-with ELC event linking for hardware-triggered A/D conversion and PWM dead-time generation. Communication is supported by two IEEE 1588-compliant Ethernet MACs, three CAN 2.0B channels (32 mailboxes each), USB 2.0 FS host/function, SDHI/MMCIF, QSPI, and RIIC (up to 1 Mbps).

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572NNDDFB#30?

The R5F572NNDDFB#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 instruction pipeline, double-precision FPU, and zero-wait-state access to 512 KB of SRAM at ≤120 MHz - enabling real-time motion control and protocol stack processing without external cache.

Does the R5F572NNDDFB#30 support IEEE 1588 Precision Time Protocol (PTP)?

Yes, the R5F572NNDDFB#30 integrates a dedicated EPTPC (Precision Time Protocol Controller) module that works with its dual Ethernet MACs to provide hardware timestamping compliant with IEEE 1588-2008. Timestamp resolution is sub-microsecond, and the module supports PTP event message handling, sync/follow-up/delay_req/delay_resp packet processing, and hardware-assisted correction for link delay - critical for time-sensitive networking in industrial PLCs.

What security features does the R5F572NNDDFB#30 include for firmware protection?

The R5F572NNDDFB#30 includes Trusted Secure IP (TSIP) with AES-128/192/256 encryption engines, secure boot ROM with SHA-256 signature verification, register write protection, memory protection unit (MPU), and IEC60730 Class B self-test functions. These features allow secure firmware authentication, encrypted OTA updates, and runtime integrity checks - eliminating reliance on external secure elements in certified industrial equipment.

How many GPIOs does the R5F572NNDDFB#30 offer, and what are their electrical characteristics?

The R5F572NNDDFB#30 provides 182 general-purpose I/O pins in its 224-pin LFBGA package. Of these, 19 pins are 5-V tolerant, all support configurable pull-up resistors and open-drain output mode, and drive strength is software-selectable. This flexibility enables direct interfacing with legacy 5-V sensors, industrial fieldbus transceivers, and optocoupled isolation circuits without level-shifting components.

What graphics capabilities does the R5F572NNDDFB#30 support for HMI applications?

The R5F572NNDDFB#30 integrates a Graphic-LCD Controller (GLCDC) supporting RGB, YUV, and serial RGB interfaces up to WXGA resolution, plus a 2D Drawing Engine (DRW2D) for hardware-accelerated bitblt, alpha blending, and rectangle fill operations. Combined with 1 Mbyte on-chip SRAM, it renders complex GUIs directly without external frame buffer - reducing latency, power, and PCB complexity in embedded HMI designs.
