R5K574MCB4AE#00

For designs that refuse to compromise anywhere in the RX74M matrix, the R5K574MCB4AE#00 is the full-house ordering code: 1 MB of code MRAM with 48 KB of data MRAM and 1.5 MB of ECC SRAM behind a 600 MHz RXv3e core, a two-channel EtherCAT slave, three CAN FD channels and a gigabit Ethernet MAC with TSN switch, all in the 320-ball LFBGA. The security block (AES, RSA, ECC and SHA engines with Protect Zone) and OctaFlash execute-in-place with on-the-fly decryption carry over unchanged, on a 1.62 V to 3.63 V supply. Selection advice: the in-catalog R5K574M6B4AE#00 has the same interface signature at half the memory, and the R5K574MCA4AE#00 matches the 1 MB size but falls back to CAN 2.0 - this B code is the only in-family combination of full memory, top clock, EtherCAT and CAN FD. Parameters verified against Renesas Electronics documentation.
