Product details
Overview
R5F5631GDDFP#V0 from Renesas is a 100 MHz, 32-bit RX CPU core microcontroller in the RX631 Group, featuring 512 KB on-chip flash memory, 64 KB SRAM, 32 KB data flash, 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, I²C (4 channels), SPI (3 channels), and operates from a single 2.7–3.6 V supply across –40 to +105°C.
For engineers reviewing the R5F5631GDDFP#V0 datasheet, R5F5631GDDFP#V0 pinout, R5F5631GDDFP#V0 application, or R5F5631GDDFP#V0 equivalent, this device serves as a high-integration, temperature-robust MCU for industrial control, motor drive, and embedded HMI applications requiring deterministic real-time performance, cryptographic acceleration (AES-128/192/256), and IEC60730 safety compliance support.
Technical Context
The R5F5631GDDFP#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. It integrates a memory protection unit (MPU), JTAG/FINE debug interface, and supports little-endian or big-endian data arrangement.
Its peripheral set excludes Ethernet MAC and SDRAM controller (distinguishing it from RX63N), but includes dual CAN modules (2 × 32-mailbox), USB 2.0 OTG-capable transceiver, DEU for AES encryption/decryption, and RTC with battery backup - all optimized for deterministic operation in extended-temperature industrial environments.
