FAQ

What is the maximum operating frequency of the R5F572NDDGFP#10?

The R5F572NDDGFP#10 operates at a maximum CPU frequency of 240 MHz, achieved via its on-chip PLL with fractional divider. This frequency is guaranteed across the full industrial temperature range (-40°C to +85°C) when supplied with 3.3 V ±10% and using the recommended external 8 MHz crystal. The R5F572NDDGFP#10 maintains this speed with zero wait-state access to on-chip flash due to its 6-stage superscalar pipeline and 32 KB instruction cache.

Does the R5F572NDDGFP#10 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDDGFP#10 includes a hardware IEEE 1588 v2 PTP engine with nanosecond-resolution timestamping on both transmit and receive Ethernet frames. It supports all mandatory PTP profiles including Default Profile and Power Profile, and provides dedicated registers for correction field adjustment and clock servo control - enabling sub-microsecond time synchronization without CPU overhead. This capability is integral to the R5F572NDDGFP#10's Ethernet MAC block.

What package type and pin count does the R5F572NDDGFP#10 use?

The R5F572NDDGFP#10 uses a 144-pin Low-Profile Quad Flat Package (LFQFP) with 20 mm × 20 mm body size and 0.5 mm lead pitch. This package includes an exposed thermal pad for enhanced heat dissipation and is compatible with standard JEDEC J-STD-020 reflow profiles. Pin assignments match the RX72N Group's 144-pin LFQFP footprint, ensuring mechanical and layout compatibility with existing R5F572N-series designs.

How much on-chip memory does the R5F572NDDGFP#10 provide?

The R5F572NDDGFP#10 integrates 1024 KB of on-chip flash memory with ECC protection and 512 KB of SRAM with parity checking. Flash memory is organized in dual banks to support background read-while-write operations, while SRAM includes retention capability in low-power modes. These memory resources are directly accessible via the R5F572NDDGFP#10's 32-bit AXI bus matrix, delivering sustained bandwidth up to 480 MB/s for real-time data buffering and protocol stack execution.

What security features are implemented in hardware on the R5F572NDDGFP#10?

The R5F572NDDGFP#10 includes a dedicated security engine with hardware-accelerated AES-128/256, SHA-256, and true random number generation (TRNG). It boots exclusively from immutable ROM containing a public-key verifier for signed firmware images. All cryptographic operations occur in isolated secure memory regions, and debug access is permanently disabled after secure provisioning. These features are physically embedded in the R5F572NDDGFP#10 die and require no external components to enforce secure boot or runtime encryption.
