Renesas R5F563NECDLK#U0

Overview

R5F563NECDLK#U0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 2 Mbyte on-chip flash, 128 Kbyte SRAM, and 32 Kbyte data flash-designed for industrial networking gateways requiring deterministic real-time control, secure firmware updates, and dual CAN/Ethernet coexistence.

For engineers reviewing the R5F563NECDLK#U0 datasheet, R5F563NECDLK#U0 pinout, R5F563NECDLK#U0 application, or R5F563NECDLK#U0 equivalent, this MCU delivers verified 165 DMIPS performance, hardware AES-128/192/256 encryption, 100-MHz zero-wait-state memory access, and IEC60730-compliant self-diagnostic features including CRC, oscillation-stop detection, and A/D converter diagnostics.

Technical Context

The R5F563NECDLK#U0 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code density while sustaining 100 MHz operation. It integrates dedicated DMA controllers (DMAC, EXDMAC, DTC) and an Ethernet-specific EDMAC to offload TCP/IP stack processing from the CPU.

Its clock system combines PLL-based 100 MHz ICLK with independent PCLK (≤50 MHz), FCLK (≤50 MHz), and BCLK (≤50 MHz) domains, enabling precise peripheral timing isolation. The device supports full IEEE 802.3 10/100 Mbps Ethernet via MII/RMII, USB 2.0 full-speed host/function/OTG, and three ISO11898-1 CAN channels with 32 mailboxes each.
