FAQ

What is the maximum operating frequency of the R5F572NNDGBD#20?

The R5F572NNDGBD#20 operates at a maximum frequency of 240 MHz using its RXv3 CPU core. This speed is achievable under specified voltage (1.8 V core, 3.3 V I/O) and temperature (–40°C to +85°C) conditions, with proper clock source configuration (e.g., PLL locked to external crystal or oscillator). The R5F572NNDGBD#20 achieves this performance while maintaining real-time determinism through its 16-stage superscalar pipeline and integrated memory controller.

Does the R5F572NNDGBD#20 include hardware cryptographic acceleration?

Yes, the R5F572NNDGBD#20 integrates dedicated hardware accelerators for AES-128/256 encryption/decryption, SHA-1/224/256 hashing, and a true random number generator (TRNG). These modules operate independently of the CPU, enabling secure boot, TLS handshake acceleration, and encrypted firmware updates without compromising real-time application performance. The R5F572NNDGBD#20 uses these features to meet IEC 62443-3-3 security level 2 requirements.

What package type and pin count does the R5F572NNDGBD#20 use?

The R5F572NNDGBD#20 is supplied in a 224-pin LFBGA package measuring 15 mm × 15 mm with 0.8 mm ball pitch and an exposed thermal pad. This package supports industrial temperature operation (–40°C to +85°C) and is compatible with standard reflow profiles per JEDEC J-STD-020. The R5F572NNDGBD#20 shares pin compatibility with other RX72N Group variants in the same 224-pin LFBGA configuration, simplifying migration across memory variants.

Can the R5F572NNDGBD#20 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NNDGBD#20's integrated Ethernet MAC includes full IEEE 1588 v2 hardware timestamping capability, supporting one-step and two-step clock synchronization with sub-100 ns resolution. It handles PTP event message parsing and correction field calculation in hardware, reducing software overhead. The R5F572NNDGBD#20 uses this feature to synchronize distributed motion axes in CNC machines and robotic cells with tight jitter constraints.
