Product details
Overview
R5F5631MCDFM#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 1 MB on-chip flash memory, 128 KB SRAM, 32 KB data flash, and integrated 12-bit/10-bit A/D converters. It supports USB 2.0 full-speed host/function, CAN (2 channels), up to 13 SCI interfaces, I²C (4 channels), and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI, motor control, and networked sensor nodes requiring deterministic real-time performance without Ethernet.
For engineers reviewing the R5F5631MCDFM#V0 datasheet, R5F5631MCDFM#V0 pinout, R5F5631MCDFM#V0 application, or R5F5631MCDFM#V0 equivalent, key selection considerations include its RX631-specific feature set (no Ethernet MAC), 176-pin LQFP package with 133 general-purpose I/Os, 5-V-tolerant pins, and support for IEC60730 safety compliance functions including CRC, self-diagnostic A/D, and oscillation-stop detection.
Technical Context
The R5F5631MCDFM#V0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, supporting 165 DMIPS at 100 MHz and IEEE-754 single-precision floating-point operations. Its memory subsystem includes zero-wait-state 100 MHz flash and SRAM, plus background-programmable 32 KB data flash rated for 100,000 erase/write cycles.
Peripheral integration centers on deterministic real-time control: dual TPU units (12 channels total), MTU2 (6 channels), four 8-bit TMRs, and two 16-bit compare-match timers - all capable of generating synchronized A/D conversion triggers. Communication is served by dual CAN modules (32 mailboxes each), USB 2.0 host/function/OTG, and flexible SCI variants supporting UART, SPI, I²C, and LIN protocols.

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, 2 MB flash, same 176-pin LQFP package | Suitable where 10/100 Mbps Ethernet connectivity is required alongside USB/CAN | Select when network stack offload (TCP/IP in hardware) and larger code space are needed; requires additional PHY and magnetics |
| R5F566TEBDFP | RX66T Group; 160 MHz CPU, 2 MB flash, enhanced timer resolution (GPT), no USB host | Optimized for high-precision motor control with dual GPT units and encoder interfaces | Prefer for servo drives demanding >100 ns PWM dead-time control and higher computational throughput; lacks USB but adds EtherCAT slave support |
Compared with R5F5631MCDFM#V0, R5F563NEDDFC adds Ethernet capability and doubles flash capacity but increases BOM cost and design complexity, while R5F566TEBDFP trades USB host and broader peripheral flexibility for superior motor-control timing precision and higher clock speed - making it ideal for motion-critical applications where network connectivity is secondary.
