Product details
Overview
R5F5631EDGFC#V0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 512 KB on-chip flash memory, 128 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, and integrated 10-/12-bit A/D converters - designed for industrial control systems requiring deterministic real-time response and functional safety support (IEC60730).
For engineers reviewing the R5F5631EDGFC#V0 datasheet, R5F5631EDGFC#V0 pinout, R5F5631EDGFC#V0 application, or R5F5631EDGFC#V0 equivalent, this MCU delivers verified low-power operation (500 μA/MHz), hardware CRC, independent watchdog timer (IWDT), temperature sensor (±1°C), and USB 2.0 function-only interface - critical for embedded HMI, motor control, and smart sensor node designs.
Technical Context
The R5F5631EDGFC#V0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and MPU support. It operates at up to 100 MHz (165 DMIPS), supports little- or big-endian data arrangement, and includes dedicated on-chip multiplier (1-cycle) and divider (2-cycle) units.
This device belongs to the RX631 Group - distinguished from the RX63N Group by absence of Ethernet MAC, SDRAM controller, and external bus interface. It retains full USB 2.0 function-mode capability, CAN v2.0B (2 channels, 32 mailboxes), 13 SCI channels (including LIN/IEBus), and 4 RIIC interfaces (1 FM+), all operating under a unified clock tree with ICLK/PCLK/FCLK/BCLK domain separation.

The R5F5631EDGFC#V0 integrates a USB 2.0 function-only module compliant with full-speed (12 Mbps) operation. It supports bus-powered and self-powered modes, includes 2 KB of on-chip transfer RAM, and implements standard USB device enumeration. Host or OTG functionality is not present - those features require RX63N Group devices such as R5F563NEDDFC.
How much on-chip memory does the R5F5631EDGFC#V0 include?
The R5F5631EDGFC#V0 contains 512 KB of on-chip main flash memory (zero-wait-state at 100 MHz), 128 KB of SRAM (also zero-wait-state), and 32 KB of reprogrammable data flash (rated for 100,000 erase/write cycles). This memory configuration supports complex firmware with real-time data logging, parameter storage, and dual-bank updates without external memory components.
Is the R5F5631EDGFC#V0 qualified for industrial temperature operation?
Yes, the R5F5631EDGFC#V0 is rated for −40°C to +85°C operation (D version), meeting industrial-grade thermal and reliability requirements. It includes a calibrated on-die temperature sensor (±1°C accuracy) and supports battery-backed RTC operation down to 2.3 V, enabling robust functionality across extended ambient conditions typical in factory automation and outdoor equipment deployments.
