Does the R5F56316SGFC#V0 include an Ethernet MAC, and what interfaces does it support?

Yes, the R5F56316SGFC#V0 integrates a full-featured Ethernet MAC (ETHERC) supporting 10/100 Mbps operation in both full- and half-duplex modes. It supports IEEE 802.3u-compliant MII and RMII physical layer interfaces, Magic Packet™ wake-on-LAN detection, and IEEE 802.3x flow control. The dedicated EDMAC controller with 2 KB TX/RX FIFOs enables zero-copy packet handling-critical for low-latency industrial Ethernet implementations using the R5F56316SGFC#V0.

What are the flash and RAM capacities of the R5F56316SGFC#V0, and how are they configured?

The R5F56316SGFC#V0 contains 1.5 MB of on-chip main flash memory and 192 KB of SRAM, both accessible at 100 MHz with zero wait states. Flash supports on-board programming and is segmented for secure boot partitioning; SRAM is unified for instructions and data, with backup capability during deep software standby. These capacities are fixed for this specific variant and confirmed in Renesas document R01DS0098EJ0180-enabling robust firmware deployment and real-time data buffering in the R5F56316SGFC#V0's target applications.
