Product details
Overview
R5F5631BDDLK#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 no Ethernet controller. It integrates a 12-bit A/D converter (21 channels), 10-bit A/D converter (8 channels), dual 10-bit D/A converters, RTC with battery backup, USB 2.0 host/function interface, CAN (2 channels), 13 SCI channels, 4 I²C interfaces, and operates from a single 2.7–3.6 V supply across –40 to +85°C.
For engineers reviewing the R5F5631BDDLK#V0 datasheet, R5F5631BDDLK#V0 pinout, R5F5631BDDLK#V0 application, or R5F5631BDDLK#V0 equivalent, this MCU targets industrial HMI, motor control, and networked embedded systems requiring deterministic real-time performance, cryptographic acceleration (AES-128/192/256), and IEC60730-compliant safety functions without Ethernet PHY dependency.
Technical Context
The R5F5631BDDLK#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports IEEE-754 single-precision floating-point arithmetic, two MAC units, and a 32-bit multiplier executing in one cycle - delivering 165 DMIPS at 100 MHz.
Its peripheral set includes a dedicated DMA controller (4-channel DMAC), EXDMAC (2-channel), DTC, and module stop functionality for low-power operation. The device lacks Ethernet MAC and sub-clock oscillator support per RX631 Group specification, distinguishing it from RX63N variants while retaining full USB 2.0 OTG, CAN, and parallel data capture capability in compatible packages.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F5631BDDFK#V0 | LQFP-144 package (PLQP0144KA-A); identical flash/SRAM/peripherals but different pinout and thermal profile | Suitable for through-hole prototyping or reflow-compatible designs where TFLGA assembly is unavailable | Select when board-level manufacturing constraints require LQFP instead of TFLGA; verify PCB layout compatibility due to differing footprint and thermal pad requirements |
| R5F5630BDDLK#V0 | RX630 Group variant: same 1 MB flash/128 KB SRAM but reduced peripheral count - no USB, only 1 CAN channel, 8 SCI channels | Targeted at cost-sensitive, non-connectivity applications like basic sensor nodes or simple timers | Choose only if USB and second CAN channel are unnecessary; not suitable for HMI or gateway roles requiring full RX631 feature set |
Compared with R5F5631BDDLK#V0, the R5F5631BDDFK#V0 offers identical functionality in an LQFP package for easier assembly, while R5F5630BDDLK#V0 sacrifices USB and CAN flexibility for lower BOM cost - making the original part optimal for balanced connectivity, compute, and analog I/O in compact industrial designs.
