The R5F572MNDGBD#20 is a Renesas RX-series 32-bit MCU built around the RXv3 core running at 240 MHz. That clock rate puts it at the top end of the RX family, meaning it can handle sensor fusion, motor control loops, or Ethernet protocol stacks without breaking a sweat. The 4 MB on-chip flash and 1 MB SRAM let you keep the application and data buffers internal — no external memory chip, no extra BOM line.
Industrial temperature grade and BGA package — layout and environment
The 224-LFBGA (13x13 mm) package with 0.5 mm ball pitch demands a 4-layer PCB at minimum for fan-out — a two-layer board will struggle to route the inner balls. No lab, no bench: if your board is already laid out for a BGA, this part fits; if you are hand-prototyping, budget for a stencil and reflow oven.
How it compares to the R5F566TAAGFP#30 — same core, lower speed
The closest peer in the RX family is the R5F566TAAGFP#30, which also uses the RXv3 core but runs at 160 MHz. That part comes in a 100-pin LQFP with 72 I/O and no Ethernet or USB OTG.
