Renesas R5F563NBDDBG#U0

Overview

R5F563NBDDBG#U0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller with integrated Ethernet MAC, full-speed USB 2.0 host/function/OTG, three CAN channels, 12-bit and 10-bit A/D converters (21 and 8 channels), dual 10-bit D/A outputs, hardware AES encryption (DEU), and 1 Mbyte on-chip flash memory. It operates from a single 2.7–3.6 V supply and supports industrial temperature range (−40 to +85°C) in a 176-pin LFBGA package (PLBG0176GA-A). This MCU targets networked industrial control and embedded gateway applications requiring real-time processing, secure communication, and mixed-signal interfacing.

For engineers reviewing the R5F563NBDDBG#U0 datasheet, R5F563NBDDBG#U0 pinout, R5F563NBDDBG#U0 application, or R5F563NBDDBG#U0 equivalent, key selection considerations include its Ethernet MAC + RMII/MII support, 13-channel SCI with LIN/IEBus capability, 176-pin LFBGA footprint, 128 Kbytes SRAM, and RX63N Group-specific features such as RTC with battery backup, deep software standby mode, and IEC60730 safety functions.

Technical Context

The R5F563NBDDBG#U0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. It integrates dedicated DMA controllers-including EXDMAC for TFT LCD transfer and EDMAC for Ethernet-alongside DTC for peripheral-triggered transfers without CPU intervention.

Its clock system combines external crystal (4–16 MHz), internal HOCO (50 MHz), LOCO (125 kHz), and PLL for flexible domain partitioning: ICLK up to 100 MHz (CPU), PCLK up to 50 MHz (peripherals), FCLK/BCLK up to 50 MHz (Flash/external bus). The MPU enforces memory protection, while register write protection safeguards critical configuration registers.
