R5K574N6C4FP#10

The R5K574N6C4FP#10 brings the RX74N family into a 100-pin LFQFP (14 mm x 14 mm, 0.5 mm pitch) for designs that need a leaded, inspection-friendly package, supplied in full-carton trays. This code runs the RXv3e core at 480 MHz with a double-precision FPU, 512 KB of code MRAM, 48 KB of data MRAM and 1.5 MB of ECC SRAM, and keeps the family's OctaFlash execute-in-place with on-the-fly decryption. Connectivity is trimmed to the package: 75 I/O, one 10/100 Ethernet channel — the gigabit MAC is not routed on this code — USB full-speed and CAN FD, while the security block (AES, RSA, ECC, SHA engines and Protect Zone) and the -40 °C to +125 °C junction range are unchanged. Selection note: pick the C4FP code for cost-sensitive networked controllers assembled on QFP lines; if the product roadmap needs gigabit Ethernet, 600 MHz or the full 200 I/O, design directly on the LFBGA-320 A4AE code to avoid a later board spin.
