Product details
Overview
R5F5631FDGFP#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 2 MB on-chip flash memory, 256 KB SRAM, 32 KB data flash, single-precision IEEE-754 FPU, and integrated 12-bit/10-bit A/D converters. It supports USB 2.0 full-speed host/function/OTG, CAN (2 channels), up to 13 SCI interfaces, 4 I²C buses, and operates across -40°C to +85°C for industrial embedded control applications.
For engineers reviewing the R5F5631FDGFP#V0 datasheet, R5F5631FDGFP#V0 pinout, R5F5631FDGFP#V0 application, or R5F5631FDGFP#V0 equivalent, this MCU delivers deterministic real-time performance with MPU support, low-power modes, hardware CRC, AES encryption (DEU), and JTAG/FINE debugging - critical for IEC60730-compliant safety systems and connected industrial devices.
Technical Context
The R5F5631FDGFP#V0 implements the CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 165 DMIPS at 100 MHz. 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 a dedicated 125-kHz LOCO oscillator.
Its peripheral set includes a 4-channel DMAC, 2-channel EXDMAC, DTC, Ethernet MAC (excluded in RX631 Group), and parallel data capture unit (PDC) - though PDC is not available in this 100-pin LQFP variant per Table 1.2. The device uses PLQP0100KB-A package (100-pin LQFP, 14 × 14 mm, 0.5-mm pitch) and belongs to the D-version temperature grade.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NFDGFP#V0 | RX63N Group variant with identical pinout and package but adds Ethernet MAC and EDMAC; 2 MB flash, 256 KB SRAM, same 100-pin LQFP | Required where IEEE 802.3 10/100 Mbps connectivity is needed - e.g., industrial Ethernet I/O modules or gateway edge nodes | Select R5F563NFDGFP#V0 only if Ethernet PHY integration is mandatory; otherwise R5F5631FDGFP#V0 reduces cost and complexity |
| R5F566TEBDFP#30 | RX66T Group part in same 100-pin LQFP; higher 160 MHz CPU, enhanced timer (GPT), no DEU or USB OTG; 1 MB flash, 128 KB SRAM | Optimized for motor control with GPT and encoder interfaces; lacks USB/DEU but offers superior PWM resolution and timing accuracy | Choose R5F566TEBDFP#30 for servo drive or inverter control; retain R5F5631FDGFP#V0 when USB, crypto, or broad peripheral coverage is prioritized |
