Product details
Overview
R5F5631YDDFB#V0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 1 MB on-chip flash memory, 256 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, 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, 4 I²C buses, and operates from a 2.7–3.6 V supply across –40 to +85°C.
For engineers reviewing the R5F5631YDDFB#V0 datasheet, R5F5631YDDFB#V0 pinout, R5F5631YDDFB#V0 application, or R5F5631YDDFB#V0 equivalent, this MCU targets industrial HMI, motor control with real-time PWM, networked sensor nodes requiring USB/CAN connectivity, and safety-compliant embedded systems needing IEC60730 support functions including CRC, self-diagnostic A/D, and oscillation-stop detection.
Technical Context
The R5F5631YDDFB#V0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and MPU support. It executes at 165 DMIPS @ 100 MHz and integrates dedicated hardware accelerators including a 32×32→64-bit multiplier (1-cycle), divider (2-cycle), and AES engine (128/192/256-bit key, ECB/CBC mode).
Its peripheral set excludes Ethernet MAC and SDRAM controller (distinguishing it from RX63N), but includes dual CAN modules (32 mailboxes each), MTU2/TPU timers for multi-phase PWM and input capture, PDC for parallel image data acquisition, and independent watchdog (IWDT) driven by a dedicated 125-kHz LOCO oscillator - all synchronized to configurable clock domains (ICLK/PCLK/FCLK/BCLK).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFB#V0 | RX63N variant with identical package and pinout, but adds Ethernet MAC, SDRAM controller, and RTC battery backup - requires additional magnetics and layout space | Suitable for gateway-class devices needing TCP/IP stack offload and external memory expansion | Select only if Ethernet or SDRAM is mandatory; otherwise R5F5631YDDFB#V0 offers lower BOM cost and simpler layout |
| R5F566TADDFB#V0 | RX66T variant with same 144-LQFP package, higher 160 MHz CPU, enhanced MTU3 timers, and built-in encoder interface - no data flash or USB host | Optimized for high-performance motor control with complex motion profiles and real-time EtherCAT slave support | Choose when >100 MHz deterministic timing, advanced PWM, or industrial Ethernet slave capability is required |
Compared with R5F563NEDDFB#V0, the R5F5631YDDFB#V0 omits Ethernet and SDRAM to reduce complexity and cost for non-gateway applications; versus R5F566TADDFB#V0, it retains USB host and data flash at lower clock speed - making it optimal for cost-sensitive, USB-connected industrial controllers with local firmware update needs.
