Product details
Overview
R5F5631DDDLJ#U0 from Renesas is a 100 MHz 32-bit RXv1 CPU-based microcontroller in the RX631 Group, featuring 1.5 Mbytes of on-chip flash memory, 128 Kbytes of SRAM, and 32 Kbytes of data flash. It integrates a 12-bit A/D converter (21 channels), 10-bit A/D converter (8 channels), dual 10-bit D/A converters, Ethernet MAC (not present - RX631 Group excludes Ethernet), USB 2.0 host/function interface, CAN v2.0B (2 channels), and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI and networked sensor nodes requiring deterministic real-time control with rich peripheral integration.
For engineers reviewing the R5F5631DDDLJ#U0 datasheet, R5F5631DDDLJ#U0 pinout, R5F5631DDDLJ#U0 application, or R5F5631DDDLJ#U0 equivalent, key selection criteria include its RX631 Group identity (no Ethernet), 100-MHz FPU-enabled core, 177-pin TFLGA-compatible footprint (PTLG0100JA-A, 100-pin, 0.65-mm pitch), IEC60730 safety support, and compatibility with Renesas E20/E1 debug interfaces.
Technical Context
The R5F5631DDDLJ#U0 implements the RXv1 32-bit CISC Harvard architecture with 5-stage pipeline, IEEE-754 single-precision FPU, and MPU for memory protection. It supports little-endian instruction/data layout and includes dedicated hardware for CRC calculation (X8/X16 polynomials), AES encryption (128/192/256-bit keys, ECB/CBC), and self-diagnostic A/D functions per IEC60730 Class B requirements.
Its clock system combines external crystal (4–16 MHz) with internal PLL, LOCO (125 kHz), and HOCO (50 MHz) oscillators, enabling independent domain clocking: ICLK up to 100 MHz (CPU), PCLK up to 50 MHz (peripherals), FCLK/BCLK up to 50 MHz (Flash/external bus). Four low-power modes - Sleep, All-module Clock Stop, Software Standby, and Deep Software Standby - are supported with RTC battery backup capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NDDDLJ#U0 | RX63N Group; includes Ethernet MAC, SDRAM controller, larger pin count (145/177-pin), higher flash/SRAM options | Suitable for Ethernet-connected gateways and HMI with external SDRAM graphics buffer | Select when Ethernet PHY interface and >128 KB SRAM are required; not pin-compatible with R5F5631DDDLJ#U0 |
| R5F562T7DDFK#30 | RX62T Group; 100 MHz, no Ethernet, 512 KB flash, 64 KB RAM, 100-pin LQFP, supports motor control PWM with 3-phase complementary outputs | Optimized for inverter-driven motor control with hardware timer synchronization and dead-time insertion | Prefer for BLDC/PMSM servo drives; lacks USB OTG, DEU, and IEC60730 features of R5F5631DDDLJ#U0 |
Compared with R5F5631DDDLJ#U0, the RX63N alternative adds Ethernet and SDRAM support but increases BOM cost and layout complexity, while the RX62T offers superior motor control peripherals at the expense of security and USB functionality - making R5F5631DDDLJ#U0 optimal for balanced industrial connectivity with safety and encryption.

FAQ
What is the maximum operating frequency and core architecture of the R5F5631DDDLJ#U0?
The R5F5631DDDLJ#U0 operates at a maximum frequency of 100 MHz and uses the 32-bit RXv1 CPU core with a 5-stage pipeline, IEEE-754 single-precision floating-point unit, and memory protection unit. Its architecture delivers 165 DMIPS performance and supports ultra-compact variable-length instructions for efficient code density - critical for embedded applications with constrained flash resources. The R5F5631DDDLJ#U0 leverages this core for deterministic real-time execution in industrial control loops.
Does the R5F5631DDDLJ#U0 include an Ethernet controller?
No, the R5F5631DDDLJ#U0 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 (R01DS0098EJ0180, Section 1.2, Table 1.2). The R5F5631DDDLJ#U0 instead emphasizes USB 2.0 full-speed host/function/OTG, dual CAN, and extensive serial interfaces - making it suitable for non-Ethernet industrial networks where USB configurability and CAN robustness are prioritized over 10/100 Mbps wired LAN connectivity.
What package type and pin count does the R5F5631DDDLJ#U0 use?
The R5F5631DDDLJ#U0 uses the PTLG0100JA-A package: a 100-pin Thin Fine-Pitch Land Grid Array measuring 7 × 7 mm with 0.65-mm ball pitch. This TFLGA package supports high I/O density in compact footprints and is compatible with standard surface-mount assembly processes. It differs from larger RX631 variants (e.g., 144-pin LQFP or 145-pin TFLGA) and is not pin-compatible with RX63N devices - requiring dedicated PCB layout for the R5F5631DDDLJ#U0.
Which safety standards does the R5F5631DDDLJ#U0 support for industrial certification?
The R5F5631DDDLJ#U0 includes hardware features aligned with IEC60730 Class B compliance, including oscillation-stop detection, built-in CRC calculator (supporting X8/X16 polynomials), independent watchdog timer (IWDT), self-diagnostic A/D converter test, and register write protection. These capabilities reduce external component dependencies for functional safety certification in household appliances and industrial controls. The R5F5631DDDLJ#U0 does not include ASIL-B or ISO 26262 certification out-of-box but provides foundational hardware blocks for customer-led safety qualification.
What are the flash and RAM capacities of the R5F5631DDDLJ#U0?
The R5F5631DDDLJ#U0 integrates 1.5 Mbytes of on-chip main flash memory and 128 Kbytes of SRAM - both operating at full speed with zero wait states at 100 MHz. It also includes 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles, supporting parameter storage and firmware update staging. These memory resources are fixed for this specific part number and differ from other RX631 variants offering 768 KB, 1 MB, or 2 MB flash options - confirming the R5F5631DDDLJ#U0's positioning for mid-complexity industrial applications.
