FAQ

What is the maximum operating frequency and CoreMark score of the R5F572NDDDLK#20?

The R5F572NDDDLK#20 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark. This performance stems from the RXv3 CPU core's efficient instruction pipeline, collective register bank save function, and dual-bank flash architecture that enables zero-wait-state execution at 120 MHz and cache-hit access at 240 MHz - making R5F572NDDDLK#20 suitable for computationally intensive industrial control tasks.

Does the R5F572NDDDLK#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F572NDDDLK#20 supports IEEE 1588 via its integrated EPTPC (Precision Time Protocol Controller) module working in conjunction with the ETHERC Ethernet MAC. Timestamping is performed in hardware on packet ingress/egress, and the EPTPC provides registers for offset correction, delay measurement, and synchronization with external clocks - enabling sub-microsecond time alignment across distributed R5F572NDDDLK#20-based nodes in industrial networks.

What package type and pin count does the R5F572NDDDLK#20 use?

The R5F572NDDDLK#20 uses the PLQP0176KB-C package: a 176-pin Low-profile Quad Flat Package with 24 mm × 24 mm body size and 0.5 mm lead pitch. It provides 136 general-purpose I/O pins (182 total I/O capable in larger variants), 19 of which are 5-V tolerant - matching industrial interface voltage levels without level shifters. This package is fully supported in Renesas' e2 studio and QE tools for R5F572NDDDLK#20 development.

How does the R5F572NDDDLK#20 handle secure firmware updates and cryptographic operations?

The R5F572NDDDLK#20 integrates Trusted Secure IP (TSIP) - a hardware cryptographic engine supporting AES-128/192/256 encryption/decryption, key wrapping, and random number generation. Combined with dual-bank flash and secure boot ROM, it enables authenticated, encrypted over-the-air updates. The TSIP operates independently of the CPU, ensuring deterministic timing and protection against side-channel attacks - fulfilling IEC 62443-3-3 requirements for R5F572NDDDLK#20-based secure devices.

Can the R5F572NDDDLK#20 drive a graphic LCD directly, and what interfaces does it support?

Yes, the R5F572NDDDLK#20 includes a dedicated Graphic-LCD Controller (GLCDC) and 2D Drawing Engine (DRW2D). It supports RGB parallel interfaces up to 18-bit color depth, various timing modes (TFT, STN), and direct connection to common industrial LCD panels. The DRW2D accelerates bitblt, line draw, and polygon fill operations - offloading the CPU and enabling smooth GUI rendering on displays up to WVGA resolution without external graphics memory. This capability is fully enabled on the R5F572NDDDLK#20.
