Product details
Overview
R5F5631NDGFL#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, 32 KB data flash, and integrated 12-bit/10-bit A/D converters, 10-bit D/A converters, RTC, and CAN interface - designed for industrial control and networked embedded systems without Ethernet.
For engineers reviewing the R5F5631NDGFL#V0 datasheet, R5F5631NDGFL#V0 pinout, R5F5631NDGFL#V0 application, or R5F5631NDGFL#V0 equivalent, key selection criteria include its 176-pin LQFP package, -40 to +85°C operating range, absence of Ethernet MAC (distinguishing it from RX63N), support for up to 13 channels of SCI, 4-channel I²C, 3-channel CAN, and USB 2.0 host/function capability.
Technical Context
The R5F5631NDGFL#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 165 DMIPS at 100 MHz while supporting IEEE-754 single-precision floating-point operations and dual multiply-accumulate units. It integrates a memory protection unit (MPU) and JTAG/FINE debugging interfaces.
Its peripheral set includes three CAN modules (ISO 11898-1 compliant, 32 mailboxes each), four I²C interfaces (one FM+ capable of 1 Mbps), thirteen serial communication interfaces (SCI) with flexible mode selection (asynchronous, SPI-like, I²C-like, smart-card), and a dedicated DMA controller with four channels - all clocked from a configurable PCLK domain up to 50 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
