Product details
Overview
R5F5631PDDFM#V0 from Renesas is a 100 MHz 32-bit RX CPU core 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. It supports USB 2.0 full-speed host/function interface, CAN (ISO 11898-1), up to 13 SCI channels, I²C, SPI, RTC, and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI and embedded control systems requiring deterministic real-time performance without Ethernet.
For engineers reviewing the R5F5631PDDFM#V0 datasheet, R5F5631PDDFM#V0 pinout, R5F5631PDDFM#V0 application, or R5F5631PDDFM#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LQFP), confirmed peripheral channel counts per package, functional distinctions from RX63N (no Ethernet MAC), and two validated alternative parts for migration or sourcing flexibility.
Technical Context
The R5F5631PDDFM#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU-delivering 165 DMIPS at 100 MHz. It integrates a memory protection unit (MPU), JTAG/FINE debug interfaces, and supports little-endian or big-endian data arrangement.
Its peripheral set excludes Ethernet MAC and EDMAC (distinguishing it from RX63N), but includes three CAN channels (32 mailboxes each), four I²C interfaces (one FM+), three RSPI channels, and a parallel data capture unit (PDC) supporting image sensor interfacing via DTC/DMAC-enabling real-time vision-assisted control in compact form factor.
