Renesas R5F5630BCDFP#V0

Overview

R5F5630BCDFP#V0 from Renesas is a 100-MHz 32-bit RX CPU-based microcontroller with single-precision IEEE-754 FPU, 1 Mbyte on-chip flash, 96 Kbytes SRAM, and 32 Kbytes data flash. It integrates USB 2.0 full-speed, CAN (3 channels), 12-bit A/D (21 ch), 10-bit D/A (2 ch), RTC, and 148 GPIO pins - deployed in industrial motor control, PLC I/O modules, and embedded HMI systems.

For engineers reviewing the R5F5630BCDFP#V0 datasheet, R5F5630BCDFP#V0 pinout, R5F5630BCDFP#V0 application, or R5F5630BCDFP#V0 equivalent, key selection criteria include its 100 MHz operation with 165 DMIPS, 1 Mbyte flash capacity in PLQP0100KB-A package, CAN/USB dual-interface support, and -40 to +85°C temperature range for industrial-grade reliability.

Technical Context

The R5F5630BCDFP#V0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for secure real-time execution. Its dual-clock domain supports independent ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (50 MHz), and BCLK (50 MHz) domains - enabling precise timing isolation between CPU, peripherals, flash interface, and external bus.

It features two independent watchdogs (WDTA and IWDTA), four low-power modes (sleep, all-module clock stop, software standby, deep software standby), and hardware-accelerated CRC calculation with three selectable polynomials - all aligned with IEC60730 Class B functional safety requirements for appliance and industrial control applications.
