For engineers reviewing the R5F572NDHDFB#30 datasheet, R5F572NDHDFB#30 pinout, R5F572NDHDFB#30 application, or R5F572NDHDFB#30 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-bank flash for safe firmware updates, 182 GPIO with 5-V tolerance, and hardware-accelerated trigonometric (TFU) and AES encryption functions.

Technical Context

The R5F572NDHDFB#30 implements the RXv3 CPU core with full 240 MHz operation, supporting 1396 CoreMark and double-precision floating-point arithmetic per IEEE 754. Its memory subsystem includes 4 MB dual-bank code flash (enabling background programming and bank-swapping), 1 MB SRAM (512 KB zero-wait up to 120 MHz), and 32 KB ECC RAM for safety-critical data storage.

Peripherals are clocked across four domains: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for Ethernet/USB/GLCDC), PCLKB (up to 60 MHz for timers/ADC), and PCLKC/PCLKD (60 MHz for dual 12-bit ADC units). The device integrates three CAN channels (ISO 11898-1), two IEEE 802.3-compliant Ethernet controllers with EPTPCb for hardware timestamping, and a dedicated TFU for real-time sine/cosine/arctangent computation.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572NDHDFB#30?

The R5F572NDHDFB#30 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark under benchmark conditions. This performance stems from its RXv3 CPU core with optimized pipeline, double-precision FPU, and zero-wait-state access to 512 KB of SRAM at ≤120 MHz. The R5F572NDHDFB#30 maintains this speed across all supported operating voltages (2.7–3.6 V) and ambient temperatures (−40°C to +85°C).

Does the R5F572NDHDFB#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDHDFB#30 supports IEEE 1588-2008 via its integrated EPTPCb (Precision Time Protocol Controller) module, which works in conjunction with the dual Ethernet MACs. It provides hardware timestamping of ingress/egress Ethernet frames with sub-microsecond resolution, enabling deterministic synchronization across distributed industrial nodes. The R5F572NDHDFB#30 does not require external timestamping ICs or software-based PTP stacks for basic profile compliance.

How many analog-to-digital converter channels does the R5F572NDHDFB#30 have, and what are their configurations?

The R5F572NDHDFB#30 integrates two independent 12-bit S12AD modules: Unit 0 offers 8 input channels, and Unit 1 offers 21 input channels - totaling 29 configurable analog inputs. Each unit has separate clock domains (PCLKC and PCLKD, both up to 60 MHz), enabling simultaneous sampling with programmable trigger sources (e.g., GPTW compare events). The R5F572NDHDFB#30 also supports self-diagnosis and analog input disconnection detection per channel.

What security features are included in the R5F572NDHDFB#30?

The R5F572NDHDFB#30 includes optional Trusted Secure IP (TSIP) with hardware-accelerated AES-128/192/256 encryption, secure key storage, and secure boot verification. It also supports memory protection unit (MPU), register write protection, oscillation-stoppage detection, and CRC accelerators for IEC 60730 Class B compliance. These features are factory-configurable and enabled via fuse settings - the R5F572NDHDFB#30 does not require external secure elements for basic firmware integrity and encrypted communication.

What package type and pin count does the R5F572NDHDFB#30 use?

The R5F572NDHDFB#30 uses the PLQP0176KB-C package: a 176-pin LQFP with 24 × 24 mm body size, 0.5 mm pitch, and exposed thermal pad. It provides 136 general-purpose I/O pins (of 182 total I/O), 19 of which are 5-V tolerant. This package matches the pinout of other 176-pin RX72N variants (e.g., R5F572MNHDFB#30), enabling footprint compatibility across flash-size variants.
