R5K574M6W4FB#10

CAN FD in a leaded 144-pin package, without paying for an EtherCAT slave the design will never use - that is the R5K574M6W4FB#10: RXv3e core at 480 MHz, 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, three channels each of CAN and CAN FD, a 10M/100M Ethernet MAC and no EtherCAT controller, in an LFQFP-144 (20 x 20 mm) with full-carton packing. It fits packaging machines, textile equipment and mid-tier motion controllers whose internal buses have moved to CAN FD while the plant network stays on standard Ethernet. Selection advice: against its same-package sibling R5K574M6V4FB#10 the only difference is the CAN FD set, so the V code is right for frozen CAN 2.0 fleets and this W code for anything already migrating; designs that do need EtherCAT in a QFP should look at the in-catalog F-signature codes instead of treating this page as a substitute.
