Product details
Overview
R5F5631MDGFM#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 768 KB on-chip flash memory, 128 KB SRAM, 32 KB data flash, and integrated 12-bit/10-bit A/D converters, 10-bit D/A converters, RTC, and CAN interface - designed for industrial control and embedded networking applications without Ethernet.
For engineers reviewing the R5F5631MDGFM#V0 datasheet, R5F5631MDGFM#V0 pinout, R5F5631MDGFM#V0 application, or R5F5631MDGFM#V0 equivalent, this MCU delivers deterministic real-time performance with IEEE-754 FPU, MPU support, JTAG/FINE debug, and IEC60730 safety features - critical for motor control, HMI, and programmable logic controller designs.
Technical Context
The R5F5631MDGFM#V0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, supporting 165 DMIPS at 100 MHz and single-cycle 32×32-bit multiplication. It integrates a memory protection unit (MPU), dual-clock domain (ICLK up to 100 MHz, PCLK up to 50 MHz), and independent watchdog timer (IWDT) driven by dedicated 125-kHz LOCO oscillator.
This device belongs to the RX631 Group - distinguished from the RX63N Group by absence of Ethernet MAC, EDMAC, and SDRAM controller. It retains full USB 2.0 host/function/OTG (full-speed), 3 CAN channels (ISO11898-1), 13 SCI interfaces, 4 RIIC channels (up to 1 Mbps), and parallel data capture unit (PDC) support for image sensor interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFC | RX63N Group; includes Ethernet MAC, EDMAC, SDRAM controller, and 2 MB flash - but same 100 MHz CPU, FPU, and peripheral set otherwise. | Required for industrial gateways needing TCP/IP stack offload or external memory expansion; not suitable where Ethernet adds cost/complexity. | Select R5F563NEDDFC only if Ethernet connectivity or >768 KB flash is mandatory; R5F5631MDGFM#V0 reduces BOM cost and layout area in standalone control nodes. |
| R5F566TEBDFP | RX66T Group; 160 MHz CPU, enhanced MTU3 timers, 32-channel 12-bit ADC, no USB/IEBus - optimized for servo drive timing precision. | Targeted at high-end servo amplifiers requiring sub-µs PWM dead-time control and dual encoder capture; lacks USB and legacy bus interfaces. | Choose R5F566TEBDFP for motion control demanding >100 MHz deterministic timing; retain R5F5631MDGFM#V0 for balanced mixed-signal + connectivity needs. |
Compared with R5F563NEDDFC, R5F5631MDGFM#V0 removes Ethernet and SDRAM support to reduce cost and power while retaining identical real-time control capability; versus R5F566TEBDFP, it trades higher clock speed and specialized timers for broader communication flexibility and lower entry price.
