R5K574M6F4FP#10

The R5K574M6F4FP#10 is the smallest RX74M ordering code that still carries both modern interfaces: a 100-pin LFQFP (14 x 14 mm, 0.5 mm pitch) running the RXv3e core at 300 MHz, with 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, a two-channel EtherCAT slave controller, CAN FD and 10/100 Ethernet channels for the plant network. Full-carton #10 packing and the -40 to +125 C junction range keep it aligned with the rest of the family. Selection advice: the in-catalog R5K574M6C4FP#10 shares this package but runs 480 MHz with classic CAN 2.0, so choose the F4FP code when CAN FD is mandatory and the lower clock is acceptable; it is the natural pick for compact EtherCAT slaves and distributed I/O heads that are assembled on QFP lines.
