FAQ

What is the maximum operating frequency of the R5F572NNDGFB#30?

The R5F572NNDGFB#30 operates at a maximum CPU frequency of 240 MHz, achieved using the on-chip PLL with external crystal (typically 12–20 MHz). This frequency is sustained across the full industrial temperature range (−40°C to +85°C) with appropriate voltage regulation (VCC = 2.7–3.6 V). The R5F572NNDGFB#30 maintains instruction throughput consistency due to its 6-stage superscalar pipeline and branch prediction unit.

Does the R5F572NNDGFB#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NNDGFB#30 includes a hardware IEEE 1588-2008 Annex D timestamping engine integrated into its Ethernet MAC. It supports one-step and two-step clock synchronization, hardware capture of PPS signals, and sub-100 ns timestamp resolution. The R5F572NNDGFB#30 does not require software intervention for packet timestamping, ensuring deterministic latency in time-critical applications like motion control.

What security features are implemented in hardware on the R5F572NNDGFB#30?

The R5F572NNDGFB#30 integrates AES-128/256, SHA-256, and RSA-2048 cryptographic accelerators, a secure boot ROM that verifies firmware hash before execution, and tamper-detection circuitry tied to VDD and reset pins. It also provides protected key storage in dedicated memory regions. These features enable the R5F572NNDGFB#30 to meet IEC 62443-3-3 SL2 requirements for secure device identity and firmware integrity.

How much on-chip flash and SRAM does the R5F572NNDGFB#30 include?

The R5F572NNDGFB#30 includes 2048 KB of on-chip flash memory with built-in ECC and background erase capability, and 512 KB of SRAM - of which 64 KB is designated as backup SRAM powered by the RTC domain. This memory configuration supports complex protocol stacks (e.g., EtherNet/IP + TLS), real-time control tasks, and secure credential storage without external memory expansion. The R5F572NNDGFB#30's flash endurance exceeds 100,000 write/erase cycles.

What package type and pin count does the R5F572NNDGFB#30 use?

The R5F572NNDGFB#30 uses a 224-pin LFBGA package measuring 15 mm × 15 mm with 0.8 mm ball pitch. It complies with JEDEC MO-270AB and is rated MSL3. This package supports high-density routing for Ethernet, CAN FD, and QSPI interfaces while maintaining thermal performance within industrial ambient limits. The R5F572NNDGFB#30's pinout is documented in Section 1.5.1 of the RX72N Group User's Manual: Hardware (Rev.1.20).
