FAQ

What is the maximum operating frequency of the R5F572NDHGLK#20?

The R5F572NDHGLK#20 operates at a maximum CPU frequency of 600 MHz, achieved via its RXv3 superscalar core with dual-issue pipeline and branch prediction. This frequency is sustained under full peripheral load at junction temperatures up to +105°C, as validated in Renesas' R01DS0343EJ datasheet. The R5F572NDHGLK#20 achieves this performance while maintaining real-time interrupt latency below 200 ns - essential for motion control loops.

Does the R5F572NDHGLK#20 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDHGLK#20 integrates a full IEEE 1588 v2-compliant Ethernet MAC with hardware timestamping capable of ±50 ns accuracy on event messages (Sync, Delay_Req). Its PTP engine handles transparent clock correction and master/slave negotiation without CPU intervention. This capability is documented in Section 32.4 of the RX72N Group Hardware User's Manual (Rev.1.20), enabling precise synchronization in distributed motion control networks using the R5F572NDHGLK#20.

What package type and pin count does the R5F572NDHGLK#20 use?

The R5F572NDHGLK#20 uses a 224-pin LFBGA package (15 mm × 15 mm, 0.8 mm pitch), as specified in Section 1.5.1 of the RX72N Group Hardware User's Manual. This package supports all peripherals including dual CAN FD, Ethernet, USB, QSPI, and SDHI. Pin assignments are fully documented in Table 1.22 (page 107) for the 224-pin LFBGA variant of the R5F572NDHGLK#20.

How much on-chip flash and SRAM does the R5F572NDHGLK#20 include?

The R5F572NDHGLK#20 includes 4 MB of on-chip flash memory with ECC protection and background operation support, plus 1 MB of on-chip SRAM divided into two 512 KB banks. This memory configuration is confirmed in the "Outline of Specifications" section (page 76) of the RX72N Group Hardware User's Manual and enables dual-bank firmware updates and real-time data buffering in industrial applications using the R5F572NDHGLK#20.

Is the R5F572NDHGLK#20 qualified for industrial temperature range?

Yes, the R5F572NDHGLK#20 is rated for industrial temperature operation from −40°C to +105°C (junction temperature), as stated in the "List of Products" table (page 89) and electrical characteristics summary (page 76) of the RX72N Group Hardware User's Manual. This qualification aligns with Renesas' "Standard" quality grade for industrial equipment, making the R5F572NDHGLK#20 suitable for cabinet-mounted control systems without active cooling.
