R5K574MCV4FB#10

The V signature brings the no-EtherCAT branch of the RX74M into a leaded package at full memory: the R5K574MCV4FB#10 runs the RXv3e core at 480 MHz in a 144-pin LFQFP, with 1 MB of code MRAM, 48 KB of data MRAM, 1.5 MB of ECC SRAM, classic CAN 2.0 and 10/100 Ethernet channels. Without the EtherCAT slave, the code addresses general industrial controllers that still want this family's memory headroom, security engines and -40 to +125 C junction range in an inspection-friendly footprint. Selection advice: within this batch, the R5K574MCC4FC#10 adds EtherCAT and moves to 176 pins at the same clock and memory, while the R5K574M6D4FB#10 keeps this 144-pin package but halves memory and switches to CAN FD with EtherCAT - the three codes cover distinct network plans, so confirm the fieldbus requirement before ordering.
