Product details
Overview
R5F5631EDDLC#U0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 2 MB on-chip flash memory, 128 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, and integrated 10-/12-bit A/D converters - designed for industrial control systems requiring deterministic real-time response and functional safety support (IEC60730).
For engineers reviewing the R5F5631EDDLC#U0 datasheet, R5F5631EDDLC#U0 pinout, R5F5631EDDLC#U0 application, or R5F5631EDDLC#U0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed peripheral set excluding Ethernet MAC, and two validated alternative MCUs with documented functional and packaging differences.
Technical Context
The R5F5631EDDLC#U0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, supporting 165 DMIPS at 100 MHz and ultra-compact variable-length instructions. It integrates MPU, JTAG/FINE debug interfaces, and four low-power modes including deep software standby with RTC backup.
Its peripheral suite includes three CAN modules (ISO11898-1 compliant, 32 mailboxes each), up to 13 SCI channels with flexible serial modes (asynchronous, SPI/I²C emulation, LIN), four I²C interfaces (one FM+), three RSPI channels, and hardware CRC/AES-128/192/256 encryption via DEU - all operating from a single 2.7–3.6 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDLC#U0 | RX63N Group variant with identical package (PLQP0176KB-A), same 2 MB flash/128 KB SRAM, but adds Ethernet MAC (10/100 Mbps MII/RMII) and removes sub-clock oscillator. | Required where wired IP connectivity (e.g., EtherNet/IP, Modbus TCP) is mandatory; unsuitable for cost-sensitive designs where Ethernet adds unnecessary BOM cost. | Select R5F563NEDDLC#U0 only if Ethernet PHY integration is required; otherwise R5F5631EDDLC#U0 offers lower system cost and reduced EMI footprint. |
| R5F566TEBDFP#U0 | RX66T Group MCU in 100-pin LQFP (PLQP0100KB-A), 1.5 MB flash, 256 KB SRAM, no Ethernet, but adds hardware floating-point accelerator and enhanced PWM timers (GPT) optimized for servo control. | Better suited for high-performance motor control (e.g., PMSM FOC) due to GPT's 32-bit resolution and dead-time insertion; lacks 176-pin I/O count for dense I/O applications. | Choose R5F566TEBDFP#U0 when advanced motor control precision outweighs I/O pin count; retain R5F5631EDDLC#U0 for general-purpose industrial control with high peripheral integration. |
Compared with R5F563NEDDLC#U0, the R5F5631EDDLC#U0 saves board space and cost by omitting Ethernet PHY support while retaining identical analog and serial peripheral density; versus R5F566TEBDFP#U0, it trades higher PWM resolution for broader I/O availability and proven qualification in legacy industrial platforms.

FAQ
What is the maximum operating frequency and core architecture of the R5F5631EDDLC#U0?
The R5F5631EDDLC#U0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core with a 5-stage CISC Harvard pipeline. It delivers 165 DMIPS performance and supports IEEE-754 single-precision floating-point operations - enabling deterministic execution of real-time control algorithms without external co-processors.
Does the R5F5631EDDLC#U0 include an Ethernet MAC controller?
No, the R5F5631EDDLC#U0 belongs to the RX631 Group and explicitly excludes the Ethernet MAC controller. This distinguishes it from the RX63N Group (e.g., R5F563NEDDLC#U0), which integrates a 10/100 Mbps Ethernet MAC with MII/RMII support. The R5F5631EDDLC#U0 relies on external PHY or alternative interfaces like CAN or RS485 for network connectivity.
What package type and pin count does the R5F5631EDDLC#U0 use?
The R5F5631EDDLC#U0 is packaged in PLQP0176KB-A: 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), supporting high-density industrial I/O expansion without requiring BGA assembly infrastructure.
How much on-chip memory does the R5F5631EDDLC#U0 integrate?
The R5F5631EDDLC#U0 integrates 2 MB of on-chip flash memory (executed at 100 MHz with zero wait states), 128 KB of SRAM (also zero-wait), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles - sufficient for storing application code, real-time variables, and field-upgradable calibration data in standalone industrial devices.
Which safety standards does the R5F5631EDDLC#U0 support out-of-the-box?
The R5F5631EDDLC#U0 includes hardware features aligned with IEC60730 Class B requirements: oscillation-stop detection, hardware CRC calculator (X⁸/X¹⁶ polynomials), independent watchdog timer (IWDT), A/D converter self-diagnostic function, and register write protection. These reduce software certification burden for household and industrial appliances.
