Product details
Overview
R5F5631WDDFP#V0 from Renesas is a 100 MHz 32-bit RX CPU-based 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, 10-bit D/A converters, RTC, USB 2.0 function controller, CAN, I²C, SPI, and SCI interfaces - designed for industrial control and networked embedded systems requiring deterministic real-time performance.
For engineers reviewing the R5F5631WDDFP#V0 datasheet, R5F5631WDDFP#V0 pinout, R5F5631WDDFP#V0 application, or R5F5631WDDFP#V0 equivalent, this MCU delivers verified 100 MHz operation, IEEE-754 FPU support, 5-V-tolerant I/Os, low-power modes (down to 500 µA/MHz), and IEC60730-compliant safety features including CRC, self-diagnostic A/D, and oscillation-stop detection.
Technical Context
The R5F5631WDDFP#V0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and MPU support - enabling ultra-compact code and fast interrupt response. It operates from a single 2.7–3.6 V supply and integrates dedicated clock domains (ICLK up to 100 MHz, PCLK up to 50 MHz) for system, peripheral, FlashIF, and external bus timing.
It belongs to the RX631 Group (non-Ethernet variant), distinguishing it from the RX63N Group by omission of Ethernet MAC and EDMAC. Its peripheral set includes three CAN channels (32 mailboxes each), up to 13 SCI channels (with LIN/Smart Card/I²C/SPI emulation), four I²C interfaces (one FM+), three RSPI modules, and parallel data capture unit (PDC) support for image sensor interfacing.

FAQ
What is the maximum operating frequency of the R5F5631WDDFP#V0?
The R5F5631WDDFP#V0 operates at a maximum system clock frequency of 100 MHz, delivering 165 DMIPS performance. This speed is sustained across its 1 MB flash and 128 KB SRAM with zero wait states, enabling deterministic real-time execution for industrial control loops and protocol stacks. The CPU core uses a 5-stage pipeline and supports dynamic voltage/frequency scaling within the 2.7–3.6 V supply range.
Does the R5F5631WDDFP#V0 include an Ethernet MAC?
No, the R5F5631WDDFP#V0 does not include an Ethernet MAC or associated EDMAC. It belongs to the RX631 Group, which omits Ethernet functionality present in the RX63N Group. This makes the R5F5631WDDFP#V0 appropriate for applications relying on CAN, USB, or serial fieldbuses instead of wired Ethernet - reducing complexity and cost where 10/100 Mbps networking is unnecessary.
What safety features does the R5F5631WDDFP#V0 provide for IEC60730 compliance?
The R5F5631WDDFP#V0 includes multiple hardware-assisted safety features required for IEC60730 Class B compliance: oscillation-stoppage detection for main/subclocks, on-chip CRC calculator (with three polynomials), independent watchdog timer (IWDT) with dedicated LOCO clock, self-diagnostic function for the 10-bit A/D converter, and frequency measurement capability via MTU/TPU modules - all verified in Renesas' functional safety documentation for the RX631 Group.
How many analog input channels does the R5F5631WDDFP#V0 support?
The R5F5631WDDFP#V0 supports 21 channels of 12-bit A/D conversion (S12ADa unit) and 8 channels of 10-bit A/D conversion (ADb unit), with shared sample-and-hold circuitry. These channels are accessible via dedicated ANxx pins and include dedicated inputs for the on-chip temperature sensor, enabling simultaneous monitoring of external sensors and internal die temperature with ±1°C accuracy.
Is the R5F5631WDDFP#V0 pin-compatible with other RX631 Group MCUs in the same package?
Yes, the R5F5631WDDFP#V0 is pin-compatible with all other RX631 Group devices in the PLQP0100KB-A (100-pin LQFP) package, including R5F5631EDDFP#V0 and R5F5630WDDFP#V0. Pin functions, power domains, and peripheral mappings are consistent across this package variant - allowing hardware reuse when scaling flash/SRAM or selecting alternate feature sets within the RX631 family.
