R5K574M6V4FB#10

The R5K574M6V4FB#10 is the simplest network configuration the RX74M offers in a leaded package: RXv3e core at 480 MHz, 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, three channels of classic CAN 2.0 with no CAN FD, a 10M/100M Ethernet MAC and no EtherCAT slave, in a 144-pin LFQFP (20 x 20 mm) with full-carton packing. It suits controller refreshes on established CAN 2.0 fleets - agricultural and construction machinery, legacy factory cells - where the bus will not migrate and a solderable QFP keeps assembly and inspection straightforward. Selection advice: this is the 512 KB counterpart of the in-catalog 1 MB R5K574MCV4FB#10 in the same package and signature, so size memory first; if CAN FD is even a possibility, its same-package sibling R5K574M6W4FB#10 adds all three FD channels at the same clock, and the EtherCAT-equipped codes from the earlier batch are a different branch entirely. Parameters verified against Renesas Electronics documentation.
