240 MHz RXv3 core with 4 MB Flash — memory headroom for complex firmware
The Renesas R5F572NNDGLK#20 is a 32-bit RXv3 microcontroller from the RX family, built for real-time control and connectivity-intensive applications. Its 240 MHz core, 4 MB of Flash program memory, 1 MB of SRAM, and 32 KB of on-chip EEPROM give it the headroom to run a full protocol stack, a graphical HMI, and a control loop without external memory. The part integrates CAN, Ethernet, USB OTG, QSPI, MMC/SD, and multiple serial interfaces, making it a single-chip candidate for industrial gateways, motor drives, and building automation controllers.
Industrial temperature grade and 111 I/O in a 7x7 mm LGA
The 145-TFLGA package (7x7 mm) packs 111 general-purpose I/O, 29 analog inputs (12-bit), and two 12-bit DACs into a footprint that saves board area versus a larger QFP. The LGA land pattern requires a solder-paste stencil and reflow profile tuned for the 0.5 mm pitch — a rework station with hot air is adequate for hand-assembly in prototype runs.
Renesas lists the R5F572NNDGLK#20 as Active (current production) with ROHS3 compliance.
