R5K574M6E4AE#00

Not every EtherCAT node needs the family's top clock, and the R5K574M6E4AE#00 is the ordering code for those designs: the RXv3e core runs at the 300 MHz tier with 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, yet the 320-ball LFBGA (17 x 17 mm) keeps the full pin resources, the two-channel EtherCAT slave and the gigabit Ethernet MAC with TSN switch. Classic CAN 2.0 covers legacy machine wiring, and supply spans 1.62 V to 3.63 V over a -40 to +125 C junction range. Selection advice: against the in-catalog R5K574M6A4AE#00 in the identical package, this code halves the clock while keeping memory, package and networking, which suits thermally or EMI-constrained controllers; designs that also need CAN FD at this clock should look at the 300 MHz F-signature codes instead.
