Product details
Overview
R5F5631BCDFB#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller featuring a single-precision IEEE-754 FPU, 1 MB on-chip flash memory, 128 KB SRAM, and integrated 12-bit/10-bit A/D converters. It supports USB 2.0 full-speed host/function, CAN (2 channels), up to 13 SCI interfaces, and operates across -40°C to +85°C in a 144-pin LQFP package. It targets industrial HMI, motor control, and networked sensor nodes requiring deterministic real-time performance.
For engineers reviewing the R5F5631BCDFB#V0 datasheet, R5F5631BCDFB#V0 pinout, R5F5631BCDFB#V0 application, or R5F5631BCDFB#V0 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing and interface details - all confirmed for the exact R5F5631BCDFB#V0 D-version part with 1 MB flash, 128 KB RAM, and PLQP0144KA-A package.
Technical Context
The R5F5631BCDFB#V0 implements the 32-bit RX CPU core with 5-stage CISC Harvard pipeline, supporting 165 DMIPS at 100 MHz and single-cycle 32×32-bit multiply. It integrates a memory protection unit (MPU), JTAG/FINE debug interfaces, and four low-power modes including deep software standby with RTC backup.
Its peripheral set excludes Ethernet MAC (distinguishing it from RX63N) but includes dual CAN modules (2 channels), USB 2.0 host/function controller, 13-channel SCI with flexible protocol modes (asynchronous, SPI/I²C emulation), and hardware-accelerated AES-128/192/256 via DEU - all synchronized to independent clock domains (ICLK up to 100 MHz, PCLK up to 50 MHz).
