Product details
Overview
R5F5631YDGFP#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 1 MB on-chip flash memory, 192 KB SRAM, and no Ethernet controller. It integrates a 12-bit A/D converter (21 channels), 10-bit A/D converter (8 channels), dual 10-bit D/A converters, real-time clock, USB 2.0 host/function interface, CAN (2 channels), and I²C (4 channels). It targets industrial HMI, motor control, and networked sensor nodes requiring deterministic real-time performance and functional safety support.
For engineers reviewing the R5F5631YDGFP#V0 datasheet, R5F5631YDGFP#V0 pinout, R5F5631YDGFP#V0 application, or R5F5631YDGFP#V0 equivalent, key selection criteria include its RX631 Group identity (no Ethernet MAC), 176-pin LQFP package (PLQP0176KB-A), -40°C to +85°C operating range (D version), 2.7–3.6 V supply, and IEC60730-compliant self-test features including CRC, IWDT, and A/D self-diagnostic.
Technical Context
The R5F5631YDGFP#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports IEEE-754 single-precision floating-point arithmetic and includes two multiply-and-accumulate units plus a 32-bit multiplier executing in one cycle.
Its peripheral set is optimized for deterministic real-time control: MTU2 and TPU timers provide PWM, input capture, and phase-counting modes; the DTC and DMAC enable zero-CPU-overhead data movement; and the DEU delivers AES-128/192/256 encryption in ECB/CBC modes for secure firmware updates and data handling.

Does the R5F5631YDGFP#V0 include an Ethernet MAC controller?
No, the R5F5631YDGFP#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC controller present in the RX63N Group. This distinction is confirmed in Renesas documentation (R01DS0098EJ0180), where Table 1.2 shows "Not available" for Ethernet controller in all RX631 packages-including the R5F5631YDGFP#V0's 176-pin LQFP variant.
What are the memory resources available on the R5F5631YDGFP#V0?
The R5F5631YDGFP#V0 integrates 1 MB of on-chip flash memory (zero-wait-state at 100 MHz), 192 KB of SRAM (also zero-wait-state), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. These resources support complex real-time firmware, buffered sensor data acquisition, and secure firmware updates-all within the R5F5631YDGFP#V0's single-chip architecture.
