R5K574N6A4AE#00

The R5K574N6A4AE#00 is the full-configuration RX74N ordering code in a 320-ball LFBGA (17 mm x 17 mm, 0.8 mm pitch), supplied in full-carton trays. Its RXv3e core runs at the family's top speed of 600 MHz with a double-precision FPU and register-bank saving for deterministic interrupt latency, with 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM on-chip, plus execute-in-place from external OctaFlash with on-the-fly decryption. The package exposes all 200 I/O and the single Gigabit Ethernet MAC (10/100/1000) that defines the RX74N — unlike the RX74M, there is no EtherCAT on this family — together with USB high-speed, CAN FD and an SDRAM interface. AES, RSA, ECC and SHA engines with the Protect Zone function secure connected equipment, and junction operation spans -40 °C to +125 °C. Selection note: this is the code to quote when the design uses the gigabit port and full I/O count; smaller BGA and QFP codes of the RX74N trade pins, clock speed or Ethernet rate for package cost. Parameters verified against Renesas Electronics documentation.
