Product details
Overview
R5F5631YDDFP#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 1 MB on-chip flash memory, 128 KB SRAM, and 32 KB data flash. It features 12-bit/10-bit A/D converters (21/8 channels), dual 10-bit D/A outputs, Ethernet MAC (not present), USB 2.0 host/function interface, CAN v2.0B (2 channels), and operates from 2.7–3.6 V across –40 to +85°C. Used in industrial HMI, networked sensor nodes, and programmable logic controllers requiring deterministic real-time control.
For engineers reviewing the R5F5631YDDFP#V0 datasheet, R5F5631YDDFP#V0 pinout, R5F5631YDDFP#V0 application, or R5F5631YDDFP#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-A (10 × 10 mm LQFP-100), functional differentiation from RX63N, confirmed peripheral channel counts per package, and two validated alternative parts for migration or sourcing flexibility.
Technical Context
The R5F5631YDDFP#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - delivering 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 targets industrial connectivity: dual CAN modules (32 mailboxes total), up to 13 SCI channels (including LIN-capable SCId), four I²C interfaces (one FM+), three RSPI, and full-speed USB 2.0 host/function/OTG - all clocked via configurable PCLK (up to 50 MHz) independent of the 100-MHz ICLK system clock.
