R5K574M6A4AE#00

R5K574M6A4AE#00 is an RX74M-group industrial Ethernet microcontroller from Renesas in an LFBGA-320 package (17 x 17 mm, 0.8 mm pitch), built on the RXv3e core at 600 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 and a gigabit Ethernet MAC with TSN switch, on a 1.62 V to 3.63 V supply over -40 to +125 C junction. Selection advice: Renesas lists this code as Active in the RX74M ordering table; the A4AE letters pin the 512 KB MRAM configuration (the group headline figure of 1 MB applies to other codes), and the #00 suffix is the full-carton tray carrier with a 720-piece minimum - the #60 code is the same silicon in full trays at 90 pieces. Parameters verified against the Renesas RX74M product page.
