Product details
Overview
R5F5631MDGFL#V0 from Renesas is a 100 MHz 32-bit RX631 Group MCU with integrated FPU, 768 KB flash, 128 KB SRAM, 32 KB data flash, and 12-bit/10-bit A/D converters. It features USB 2.0 host/function, CAN (2 channels), 13 SCI channels, 4 I²C interfaces, 3 RSPI, RTC, 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 nodes requiring deterministic real-time control without Ethernet.
For engineers reviewing the R5F5631MDGFL#V0 datasheet, R5F5631MDGFL#V0 pinout, R5F5631MDGFL#V0 application, or R5F5631MDGFL#V0 equivalent, key selection criteria include its RX631-specific feature set (no Ethernet MAC), 176-pin PLQP0176KB-A package footprint, 768 KB flash / 128 KB RAM configuration, USB-CAN-SCI interface mix, and D-version temperature rating - all critical for BOM validation and PCB layout verification.
Technical Context
The R5F5631MDGFL#V0 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. It supports little-endian data and instruction ordering, includes MPU for memory protection, and uses JTAG/FINE for debugging.
Its peripheral set excludes Ethernet MAC and EDMAC (distinguishing it from RX63N), but retains full USB 2.0 host/function/OTG support, dual CAN modules (2 × 32-mailbox), 13-channel SCI with smart-card and LIN modes, and parallel data capture unit (PDC) compatible with 768 KB/512 KB/384 KB/256 KB flash variants in 177-/176-/145-/144-pin packages.

FAQ
What is the maximum operating frequency and core performance of the R5F5631MDGFL#V0?
The R5F5631MDGFL#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using its 32-bit RX CPU core with integrated IEEE-754 single-precision floating-point unit. Its 5-stage pipeline, variable-length instruction set, and hardware multiplier enable efficient real-time computation for industrial control algorithms without software emulation overhead.
Does the R5F5631MDGFL#V0 include an Ethernet MAC controller?
No, the R5F5631MDGFL#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and EDMAC peripherals found in the RX63N Group. This distinction is confirmed in Renesas documentation: RX63N products incorporate Ethernet while RX631 products do not. The R5F5631MDGFL#V0 instead emphasizes USB 2.0, CAN, and multiple SCI interfaces.
What flash and RAM capacities are implemented in the R5F5631MDGFL#V0?
The R5F5631MDGFL#V0 integrates 768 KB of on-chip main flash memory (with zero wait states at 100 MHz), 128 KB of SRAM (also zero wait states), and 32 KB of reprogrammable data flash rated for 100,000 write/erase cycles. These values are explicitly listed in Table 1.3 of the R01DS0098EJ0180 datasheet for this exact part number.
Which package type and pin count does the R5F5631MDGFL#V0 use?
The R5F5631MDGFL#V0 uses the PLQP0176KB-A package: a 176-pin LQFP measuring 24 mm × 24 mm with 0.5 mm pitch and an exposed thermal pad. This matches the "176-pin LQFP" entry in Table 1.3 and the mechanical drawing PLQP0176KB-A referenced on page 7 of the datasheet.
What is the operating temperature range and supply voltage specification for the R5F5631MDGFL#V0?
The R5F5631MDGFL#V0 is rated for industrial operation from –40°C to +85°C (D version) and requires a single 2.7–3.6 V supply for VCC, AVCC0, and VREFH. VBATT supports RTC backup at 2.0–3.6 V. These specifications are confirmed in Table 1.3 and Section 1.1 "Outline of Specifications" of the official Renesas datasheet R01DS0098EJ0180.
