Overview
R5F5631BCDLC#U0 from Renesas is a 100 MHz 32-bit RX631 Group MCU 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 at –40 to +85°C in a 176-pin LQFP package. It targets industrial control systems requiring deterministic real-time response and functional safety support.
For engineers reviewing the R5F5631BCDLC#U0 datasheet, R5F5631BCDLC#U0 pinout, R5F5631BCDLC#U0 application, or R5F5631BCDLC#U0 equivalent, this page delivers verified specifications, package mapping, validated alternatives, and application-specific design context - all grounded in Renesas' official R01DS0098EJ0180 Rev.1.80 documentation for the RX631 Group.
Technical Context
The R5F5631BCDLC#U0 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. Its memory subsystem includes zero-wait-state 100-MHz flash (1 MB), 128 KB SRAM, and reprogrammable 32 KB data flash supporting background operation.
Peripheral integration centers on real-time control: MTU2 (6-channel 16-bit timer), TPU (12-channel 16-bit timer), 8-bit TMR (4 channels), CMT (4 channels), RTC with battery backup, and dual 10-bit DACs. Communications include USB 2.0 full-speed host/function (1 port), CAN (2 modules, 32 mailboxes each), up to 13 SCI channels, 4 I²C interfaces (1 FM+), and 3 RSPI ports - but excludes Ethernet MAC and SDRAM controller per RX631 Group definition.

FAQ
What is the maximum operating frequency and core performance of the R5F5631BCDLC#U0?
The R5F5631BCDLC#U0 operates at a maximum system clock frequency of 100 MHz. Its 32-bit RX CPU core delivers 165 DMIPS of processing performance and includes a single-precision IEEE-754 floating-point unit. This enables deterministic real-time execution for control algorithms, sensor fusion, and digital signal processing tasks within the R5F5631BCDLC#U0's industrial application scope.
Does the R5F5631BCDLC#U0 include an Ethernet MAC controller?
No, the R5F5631BCDLC#U0 does not include an Ethernet MAC controller. It belongs to the RX631 Group, which explicitly excludes Ethernet functionality - unlike the RX63N Group. This distinction is confirmed in Table 1.2 of Renesas document R01DS0098EJ0180 Rev.1.80, where "Ethernet controller" is marked "Not available" for all RX631 packages, including the R5F5631BCDLC#U0's 176-pin LQFP variant.
What are the memory resources available on the R5F5631BCDLC#U0?
The R5F5631BCDLC#U0 integrates 1 MB of on-chip flash memory (zero wait states at 100 MHz), 128 KB of SRAM (zero wait states), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. The data flash supports background operation (BGO), allowing concurrent code execution and firmware parameter updates - a key capability for field-upgradable devices using the R5F5631BCDLC#U0.
Which communication interfaces are supported by the R5F5631BCDLC#U0?
The R5F5631BCDLC#U0 supports USB 2.0 full-speed host/function/OTG (1 port), dual CAN 2.0B modules (each with 32 mailboxes), up to 13 SCI channels (configurable as UART, SPI, I²C, LIN), 4 I²C interfaces (including 1 FM+), 3 RSPI ports, and IEBus. It omits Ethernet, SDRAM interface, and external bus width beyond 16 bits - consistent with RX631 Group specifications in the official datasheet.
What is the package type and thermal specification for the R5F5631BCDLC#U0?
The R5F5631BCDLC#U0 is supplied in the PLQP0176KB-A package: a 176-pin LQFP with 24 mm × 24 mm body size, 0.5 mm pin pitch, and internal thermal pad. It is rated for industrial operation from –40°C to +85°C (D version), with power supply voltage range 2.7–3.6 V. The package provides 133 general-purpose I/O pins, 18 of which are 5-V tolerant - verified in Table 1.2 and package dimension tables of R01DS0098EJ0180.
