Overview
R5F5631EDDFB#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 2 MB flash, 128 KB SRAM, and 32 KB data flash. It features 12-bit/10-bit ADCs (21/8 channels), dual 10-bit DACs, Ethernet MAC (not present), USB 2.0 host/function, CAN, multiple SCI/I²C/SPI interfaces, RTC, and operates from 2.7–3.6 V at –40 to +85°C in a 144-pin LQFP package. Used in industrial HMI and networked sensor gateways requiring deterministic real-time control without Ethernet PHY.
For engineers reviewing the R5F5631EDDFB#V0 datasheet, R5F5631EDDFB#V0 pinout, R5F5631EDDFB#V0 application, or R5F5631EDDFB#V0 equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral configuration for the RX631 Group D-version, and two rigorously cross-checked alternative parts - all traceable to Renesas R01DS0098EJ0180 Rev.1.80.
Technical Context
The R5F5631EDDFB#V0 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. It supports little-endian data and instruction layout, includes MPU for memory protection, and uses JTAG/FINE debugging interfaces.
This MCU belongs to the RX631 Group - distinguished from the RX63N Group by absence of Ethernet controller, SDRAM interface, and sub-clock oscillator. It retains full USB 2.0 host/function/OTG, three CAN channels (ISO 11898-1), 13 SCI channels (with LIN/Smart Card modes), four I²C interfaces (1 Mbps), and parallel data capture unit (PDC) support for image sensors.
