Product details
Overview
R5F5631BDDFP#V0 from Renesas is a 100 MHz, 32-bit RX CPU core microcontroller in the RX631 Group, featuring 1 MB on-chip flash memory, 128 KB SRAM, 32 KB data flash, and integrated 10- and 12-bit A/D converters. It supports USB 2.0 full-speed host/function, CAN (2 channels), up to 13 SCI interfaces, I²C (4 channels), and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI and networked sensor nodes requiring deterministic real-time control without Ethernet.
For engineers reviewing the R5F5631BDDFP#V0 datasheet, R5F5631BDDFP#V0 pinout, R5F5631BDDFP#V0 application, or R5F5631BDDFP#V0 equivalent, this MCU delivers verified 165 DMIPS performance, IEEE-754 single-precision FPU, hardware CRC, AES encryption (DEU), and IEC60730 safety support - critical for functional safety-compliant embedded designs with mixed analog/digital I/O and multi-protocol connectivity.
Technical Context
The R5F5631BDDFP#V0 implements the CISC Harvard-architecture RX CPU with 5-stage pipeline, variable-length instructions, and MPU-based memory protection. Its clock system integrates PLL, HOCO (50 MHz), LOCO (125 kHz), and subclock oscillator support, enabling independent domain clocking (ICLK up to 100 MHz, PCLK up to 50 MHz).
Peripheral integration includes dual DMA controllers (DMAC + DTC), MTU2/TPU timers for PWM and input capture, RTC with battery backup, 14-bit WDT and IWDT, and parallel data capture (PDC) for image sensor interfacing - all coordinated via a centralized interrupt controller (ICU) supporting 187 sources and 16 priority levels.
