Product details
Overview
R5F5631ECDBG#U0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 768 KB on-chip flash memory, 128 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, and integrated 12-bit/10-bit A/D converters. It supports Ethernet MAC (excluded in RX631), USB 2.0 full-speed host/function, CAN, I²C, SCI, and SPI interfaces - designed for industrial control systems requiring deterministic real-time response and functional safety compliance.
For engineers reviewing the R5F5631ECDBG#U0 datasheet, R5F5631ECDBG#U0 pinout, R5F5631ECDBG#U0 application, or R5F5631ECDBG#U0 equivalent, key selection criteria include its 176-pin LFBGA (PLBG0176GA-A) package, -40°C to +85°C operating range, absence of Ethernet controller (RX631 distinction), and support for IEC60730 self-diagnostic features including CRC, IWDT, and A/D converter diagnostics.
Technical Context
The R5F5631ECDBG#U0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and MPU support - enabling ultra-compact code density and memory protection for certified embedded applications. Its clock system integrates PLL, HOCO (50 MHz), LOCO (125 kHz), and subclock oscillator options, with independent frequency division for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK, and BCLK domains.
Peripheral subsystems include four-channel DMAC, two-channel EXDMAC, DTC, and dedicated timer units (MTU2, TPU, TMR, CMT) delivering precise PWM, input capture, phase counting, and conversion trigger generation. The device lacks Ethernet MAC and SDRAM controller - distinguishing it from RX63N variants - but retains full USB 2.0 OTG capability, three CAN channels (ISO11898-1), and parallel data capture unit (PDC) support for image sensor interfacing.

FAQ
What is the maximum operating frequency and core type of the R5F5631ECDBG#U0?
The R5F5631ECDBG#U0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core with 5-stage pipeline and variable-length instruction set. It delivers 165 DMIPS performance and includes an IEEE-754 single-precision floating-point unit. This core architecture enables deterministic real-time execution suitable for industrial PLCs and motor control applications where cycle-accurate timing is essential. The R5F5631ECDBG#U0 maintains full compatibility with Renesas' RX toolchain and ecosystem.
Does the R5F5631ECDBG#U0 include an Ethernet MAC controller?
No, the R5F5631ECDBG#U0 belongs to the RX631 Group and explicitly excludes the Ethernet MAC controller - a defining feature that distinguishes RX631 from the RX63N Group. This omission reduces silicon area and power consumption while maintaining full USB 2.0 OTG, CAN, SCI, I²C, and SPI connectivity. Engineers selecting the R5F5631ECDBG#U0 should plan for external Ethernet PHY or alternative network interfaces if wired LAN connectivity is required. The R5F5631ECDBG#U0 remains fully pin- and software-compatible within the RX631 family.
What memory resources are integrated in the R5F5631ECDBG#U0?
The R5F5631ECDBG#U0 integrates 768 KB of on-chip flash memory (zero-wait-state at 100 MHz), 128 KB of SRAM, and 32 KB of reprogrammable data flash rated for 100,000 write/erase cycles. The flash supports both on-board and off-board programming, while the data flash enables robust parameter storage for calibration data or field-updatable configurations. The R5F5631ECDBG#U0 does not include external bus interface or SDRAM controller - confirming its role as a self-contained, cost-optimized MCU for applications without external memory expansion needs.
Which safety standards does the R5F5631ECDBG#U0 support for functional safety certification?
The R5F5631ECDBG#U0 includes hardware features aligned with IEC60730 Class B requirements: oscillation-stop detection, independent watchdog timer (IWDT), CRC calculator with selectable polynomials (X8/X16), self-diagnostic A/D converter test, and memory protection unit (MPU). These capabilities enable certified firmware implementations for household appliances, industrial controls, and medical auxiliary devices. While the R5F5631ECDBG#U0 itself is not pre-certified, its integrated safety mechanisms reduce validation effort - a key advantage over general-purpose MCUs lacking such built-in diagnostics.
What package type and pin count does the R5F5631ECDBG#U0 use?
The R5F5631ECDBG#U0 uses a 176-pin LFBGA package (PLBG0176GA-A) with 13 × 13 mm body size and 0.8 mm ball pitch. This package provides 111 general-purpose I/O pins, 18 of which are 5-V tolerant, along with dedicated USB, CAN, and debug interface pins. The LFBGA footprint balances board space efficiency with thermal performance and manufacturability - making it suitable for compact industrial modules. The R5F5631ECDBG#U0 is not available in QFP or TFLGA variants within the RX631 Group.
