R5K574M6C4FP#10

The R5K574M6C4FP#10 is the leaded-package ordering code of Renesas' RX74M flagship MCU — the same device family whose BGA codes are already widely used, here in a 100-pin LFQFP (14 mm x 14 mm, 0.5 mm pitch) that suits optical inspection and rework-friendly assembly. This code runs the RXv3e core at 480 MHz with a double-precision FPU and register-bank saving for fast interrupt response, backed by 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, plus execute-in-place from external OctaFlash with on-the-fly decryption. Networking is the family's signature: two EtherCAT channels for real-time motion control and two 10/100 Ethernet channels (this QFP code does not carry the gigabit option), alongside CAN FD and USB full-speed. The security block integrates AES, RSA, ECC and SHA engines with a Protect Zone function, and junction operation spans -40 °C to +125 °C. Selection note: choose the C4FP code when the board process demands a QFP; if the design needs 600 MHz, gigabit Ethernet or 200 I/O, step to the BGA codes of the same family instead.
