Product details
Overview
R5F5631EDGFB#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 128 KB SRAM, 512 KB on-chip flash memory, and full-speed USB 2.0 host/function interface. It operates from a single 2.7–3.6 V supply, supports -40 to +85°C industrial temperature range, and delivers 165 DMIPS for real-time control in networked embedded systems.
For engineers reviewing the R5F5631EDGFB#V0 datasheet, R5F5631EDGFB#V0 pinout, R5F5631EDGFB#V0 application, or R5F5631EDGFB#V0 equivalent, key selection criteria include its RX631-specific feature set (no Ethernet MAC), 144-pin LQFP package, 512 KB flash/128 KB RAM configuration, and support for CAN, multiple SCI, I²C, SPI, and 12-bit A/D conversion - critical for industrial HMI, motor control, and gateway applications.
Technical Context
The R5F5631EDGFB#V0 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a single-precision IEEE-754 FPU, memory protection unit (MPU), and JTAG/FINE debugging interfaces - optimized for deterministic real-time execution in safety-aware firmware.
Its peripheral suite includes three CAN modules (ISO 11898-1 compliant, 32 mailboxes each), up to 13 SCI channels (with UART, SPI, I²C, and LIN modes), four I²C interfaces (1 Mbps max), and dual 10-bit D/A converters. Unlike RX63N variants, it omits Ethernet MAC and SDRAM controller, confirming its role as a cost-optimized, non-networked MCU variant.
