Product details
Overview
R5F5631FHDFP#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 2 MB flash, 256 KB SRAM, and 32 KB data flash. It features 10- and 12-bit A/D converters (21+8 channels), dual 10-bit D/A outputs, Ethernet MAC (not present - RX631 excludes Ethernet), USB 2.0 host/function, CAN v2.0B (2 channels), and operates from 2.7–3.6 V at –40 to +85°C in a 100-pin LQFP package. It targets industrial HMI and networked sensor nodes requiring deterministic real-time control.
For engineers reviewing the R5F5631FHDFP#V0 datasheet, R5F5631FHDFP#V0 pinout, R5F5631FHDFP#V0 application, or R5F5631FHDFP#V0 equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral channel counts per package, functional distinctions from RX63N, and two rigorously cross-checked alternative parts for migration or second-sourcing.
Technical Context
The R5F5631FHDFP#V0 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - delivering 165 DMIPS at 100 MHz. Its memory subsystem includes zero-wait-state 100-MHz flash and SRAM, plus background-programmable 32 KB data flash supporting 100,000 erase/write cycles.
Peripheral integration centers on deterministic real-time I/O: up to 134 GPIOs (17 with 5-V tolerance), 20 timers including MTU2 (6-channel), TPU (12-channel), and CMT (4-channel), plus dual A/D converters with sample-and-hold and hardware-triggered conversion start. USB 2.0 full-speed host/function and dual CAN controllers enable robust fieldbus connectivity without Ethernet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NFDHFP#V0 | RX63N variant: adds Ethernet MAC (10/100 Mbps), RMII/MII interface, EDMAC, and SDRAM controller - requires additional magnetics and layout space | Suitable for gateway-class devices needing TCP/IP stack offload; not drop-in due to added Ethernet pins and power sequencing | Select only if Ethernet connectivity is mandatory and PCB layout accommodates RMII signals and 3.3 V/2.5 V dual-supply decoupling |
| R5F566TEBDFP#V0 | RX66T Group: higher 160 MHz CPU, enhanced MTU3 timers, 3-phase PWM, no USB host - optimized for motor control, lacks CAN FD and data flash | Better suited for servo drives or inverters; incompatible USB/CAN feature set makes it unsuitable for HMI or metering use cases | Choose when real-time motor control dominates over connectivity; avoid for applications relying on USB device enumeration or CAN mailbox filtering |
Compared with R5F5631FHDFP#V0, R5F563NFDHFP#V0 adds Ethernet but increases BOM cost and layout complexity, while R5F566TEBDFP#V0 trades connectivity for deterministic motor-control peripherals - making R5F5631FHDFP#V0 optimal for balanced I/O-rich embedded systems where USB, CAN, and analog precision are co-required.

FAQ
What is the maximum operating frequency and core type of the R5F5631FHDFP#V0?
The R5F5631FHDFP#V0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and integrated IEEE-754 single-precision floating-point unit. This configuration delivers 165 DMIPS and supports deterministic real-time execution critical for industrial control loops and motor drive algorithms within the R5F5631FHDFP#V0's feature set.
Does the R5F5631FHDFP#V0 include an Ethernet MAC controller?
No, the R5F5631FHDFP#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC, EDMAC, and SDRAM controller found in the RX63N Group. This distinction is confirmed in Renesas documentation: "RX63N Group products incorporate an Ethernet controller while RX631 Group products do not." The R5F5631FHDFP#V0 retains USB 2.0 full-speed host/function, dual CAN, and 13 SCI channels for alternative wired connectivity.
What are the flash and RAM capacities of the R5F5631FHDFP#V0?
The R5F5631FHDFP#V0 integrates 2 Mbytes of on-chip main flash memory and 256 Kbytes of on-chip SRAM - both operating at 100 MHz with zero wait states. It also includes 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles, supporting background programming for firmware updates without CPU interruption in the R5F5631FHDFP#V0 implementation.
Which package and pin count does the R5F5631FHDFP#V0 use?
The R5F5631FHDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5-mm pitch. This package supports 78 general-purpose I/O pins (including 17 with 5-V tolerance), and is validated for –40 to +85°C operation (D version). Pin compatibility is specific to the RX631 Group's 100-pin LQFP footprint, distinct from 176-pin or TFLGA variants.
What communication interfaces are supported by the R5F5631FHDFP#V0?
The R5F5631FHDFP#V0 supports USB 2.0 full-speed host/function (dual-port), two CAN v2.0B modules (32 mailboxes total), 13 serial communications interfaces (SCI) with LIN/Smart Card modes, four I2C bus interfaces (RIIC), three serial peripheral interfaces (RSPI), and one IEBus channel. It omits Ethernet and USB OTG - confirming its role as a high-integration, non-gateway industrial MCU within the R5F5631FHDFP#V0 family.
