Product details
Overview
R5F5631PDGFL#V0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 512 KB on-chip flash memory, 64 KB SRAM, and no Ethernet controller. It integrates a 12-bit A/D converter (21 channels), 10-bit D/A converter (2 channels), real-time clock, USB 2.0 function controller, CAN interface (2 channels), and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI and embedded control systems requiring deterministic real-time response and secure firmware execution.
For engineers reviewing the R5F5631PDGFL#V0 datasheet, R5F5631PDGFL#V0 pinout, R5F5631PDGFL#V0 application, or R5F5631PDGFL#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed peripheral channel counts per package, functional distinctions from RX63N variants, and validated alternative MCUs for migration or second sourcing.
Technical Context
The R5F5631PDGFL#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 165 DMIPS at 100 MHz. It includes single-precision IEEE-754 FPU, memory protection unit (MPU), and JTAG/FINE debug interfaces.
Its peripheral set excludes Ethernet MAC and SDRAM controller (distinguishing it from RX63N), but retains full-speed USB 2.0 function mode, dual CAN modules (2 × 32-mailbox), 13 SCI channels (with LIN/Smart Card support), 4 RIIC interfaces (1 × FM+), and hardware AES encryption (DEU) with 128/192/256-bit key support in ECB/CBC modes.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFC | RX63N variant with 2 MB flash, 256 KB SRAM, Ethernet MAC, and SDRAM controller; same 176-pin LQFP package | Required where network connectivity (10/100 Mbps Ethernet) or external memory expansion is mandatory | Select when adding TCP/IP stack, web server, or large framebuffer support-R5F5631PDGFL#V0 lacks Ethernet PHY interface and SDRAM controller |
| R5F562T7DDFK | RX62T Group MCU: 100 MHz, 512 KB flash, 64 KB SRAM, but optimized for motor control with 3× 16-bit timer units and 12-channel 12-bit ADC | Better suited for servo/inverter control with integrated three-phase PWM generation and encoder interface | Choose for high-performance motor control where R5F5631PDGFL#V0's general-purpose timer resources are insufficient |
Compared with R5F563NEDDFC, R5F5631PDGFL#V0 trades Ethernet and memory expansion for lower cost and reduced power in standalone control; versus R5F562T7DDFK, it offers broader communication flexibility (CAN, USB, I2C) at the expense of specialized motor timing hardware.

FAQ
What is the maximum operating frequency and core type of the R5F5631PDGFL#V0?
The R5F5631PDGFL#V0 operates at a maximum frequency of 100 MHz and uses the 32-bit RXv1 CPU core with a 5-stage pipeline, delivering 165 DMIPS performance. Its architecture supports variable-length instructions, IEEE-754 single-precision floating-point operations, and hardware multiply-accumulate units-making it suitable for real-time signal processing and control algorithms in the R5F5631PDGFL#V0.
Does the R5F5631PDGFL#V0 include an Ethernet controller?
No, the R5F5631PDGFL#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and associated EDMAC peripheral 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 R5F5631PDGFL#V0 instead emphasizes USB 2.0 function mode, dual CAN, and rich serial interfaces for non-networked embedded control.
What package and pin count does the R5F5631PDGFL#V0 use?
The R5F5631PDGFL#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 × 24 mm body size and 0.5 mm pitch. This package provides 133 general-purpose I/O pins, 18 of which are 5-V tolerant, and supports full peripheral functionality including USB_DP/DM, CAN0/1, 13 SCI channels, and 21 ADC inputs-as documented in Table 1.2 of the R01DS0098EJ0180 datasheet for the RX631 Group.
How much on-chip memory does the R5F5631PDGFL#V0 integrate?
The R5F5631PDGFL#V0 integrates 512 KB of on-chip flash memory (zero-wait-state at 100 MHz), 64 KB of on-chip SRAM (zero-wait-state), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. These memory resources are fixed for this specific part number and align with the RX631 Group's mid-range configuration-distinct from larger-flash RX63N variants like R5F563NEDDFC (2 MB flash).
Is the R5F5631PDGFL#V0 suitable for IEC 60730 Class B compliance?
Yes, the R5F5631PDGFL#V0 includes multiple hardware features required for IEC 60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, independent watchdog timer (IWDT) with dedicated 125 kHz clock, self-diagnostic A/D converter test mode, and memory protection unit (MPU) for runtime partitioning. These capabilities are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0098EJ0180 datasheet for the R5F5631PDGFL#V0.
