Overview
R5F5631WHDFC#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 1 MB on-chip flash memory, 192 KB SRAM, and 32 KB data flash. It features 12-bit and 10-bit A/D converters (21 + 8 channels), dual 10-bit D/A outputs, Ethernet MAC (not present - RX631 excludes Ethernet), USB 2.0 full-speed host/function interface, CAN v2.0B (2 channels), and operates from 2.7–3.6 V at –40 to +85°C in a 176-pin LQFP package. It targets industrial HMI and networked sensor gateway applications requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F5631WHDFC#V0 datasheet, R5F5631WHDFC#V0 pinout, R5F5631WHDFC#V0 application, or R5F5631WHDFC#V0 equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral channel counts per package, functional distinctions versus RX63N, and two rigorously cross-referenced alternative parts for migration or sourcing flexibility.
Technical Context
The R5F5631WHDFC#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU-enabling 165 DMIPS at 100 MHz. Its memory subsystem includes zero-wait-state 100-MHz flash and SRAM, plus background-programmable 32 KB data flash supporting 100,000 erase/write cycles.
Peripheral integration centers on deterministic I/O control: MTU2 and TPU timers deliver PWM, input capture, and phase-counting across 12+ channels; SCI modules (up to 13) support asynchronous, SPI/I²C-emulation, and LIN modes; RIIC interfaces operate up to 1 Mbps; and the 2-channel CAN module complies with ISO 11898-1 with 32 mailboxes per channel.
