R5K574M6D4FB#10

The R5K574M6D4FB#10 fills the gap in the RX74M line where a leaded package, CAN FD and EtherCAT have to coexist: this 144-pin LFQFP code runs the RXv3e core at 480 MHz with 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, and pairs the two-channel EtherCAT slave controller with CAN FD and 10/100 Ethernet channels, since the gigabit option stays with the family's BGA codes. The full-carton #10 suffix and the -40 to +125 C junction range match the rest of the industrial line. Selection advice: compared with the in-catalog R5K574M6C4FP#10, this code moves from CAN 2.0 to CAN FD and from 100 to 144 pins at the same clock and memory; if the firmware later outgrows 512 KB, the same-batch R5K574MCD4FB#10 keeps this exact package and interface signature at 1 MB.
