Product details
Overview
R5F5631BCDLJ#U0 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, IEEE-754 single-precision FPU, and integrated 10-/12-bit A/D converters. It supports USB 2.0 full-speed host/function, CAN (2 channels), up to 13 SCI interfaces, 4 I²C channels, and operates from a 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI, motor control gateways, and networked sensor nodes requiring deterministic real-time response without Ethernet.
For engineers reviewing the R5F5631BCDLJ#U0 datasheet, R5F5631BCDLJ#U0 pinout, R5F5631BCDLJ#U0 application, or R5F5631BCDLJ#U0 equivalent, this page delivers verified specifications, package mapping to PTLG0100JA-A (100-pin TFLGA, 7 × 7 mm, 0.65-mm pitch), functional differentiation from RX63N (no Ethernet MAC), and two validated alternative parts for design flexibility.
Technical Context
The R5F5631BCDLJ#U0 implements the CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and MPU support. It executes at 165 DMIPS @ 100 MHz, includes dual multiply-accumulate units, 32-bit multiplier (1-cycle), and 32-bit divider (2-cycle), enabling high-efficiency signal processing and control loop execution.
Its peripheral set excludes Ethernet MAC and EDMAC (distinguishing it from RX63N), but retains full USB 2.0 host/function/OTG capability, CAN v2.0B (2 modules, 32 mailboxes each), and parallel data capture unit (PDC) for image sensor interfacing - all synchronized to independent clock domains (ICLK up to 100 MHz, PCLK up to 50 MHz).
