This core delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, two multiply-and-accumulate units, and support for DSP instructions. Its 5-stage pipeline and variable-length instruction set enable high code density and efficient real-time execution.

Does the R5F56514EGLK#20 support Ethernet communication, and what PHY interface options does it provide?

Yes, the R5F56514EGLK#20 integrates a full-featured Ethernet MAC compliant with IEEE 802.3, supporting 10/100 Mbps in full- and half-duplex modes. It provides both MII and RMII PHY interfaces, with dedicated pins (ETXD0–3, ERXD0–3, ETH_MDC/MDIO) and hardware-assisted DMA via EDMAC. The MAC supports flow control (IEEE 802.3x), Magic Packet wake-up, and descriptor-based packet handling to minimize CPU overhead.

What safety certifications and features does the R5F56514EGLK#20 include for industrial use?

The R5F56514EGLK#20 includes multiple hardware features targeting IEC60730 Class B compliance: oscillation-stop detection, CRC calculator (8-/32-bit polynomials), independent watchdog timer (IWDT) with windowing, self-diagnostic A/D functionality, and register write protection. It also supports Trusted Memory (TM) to prevent unauthorized code reading and MPU-based memory access control-enabling robust fault detection and recovery in safety-critical systems.

How much on-chip memory does the R5F56514EGLK#20 have, and what are its key memory architecture features?

The R5F56514EGLK#20 includes 1.5 MB of on-chip code flash memory with dual-bank structure, 640 KB of SRAM (no wait states at 120 MHz), 32 KB of reprogrammable data flash (rated for 100,000 erase cycles), and 8 KB of battery-backed standby RAM. Its flash supports background programming/erasing (BGO), zero-wait access up to 50 MHz, and ROM cache hit optimization-enabling concurrent execution and firmware updates without system interruption.

What graphics and display capabilities are integrated into the R5F56514EGLK#20?
