Renesas R5F5631ECDBG#G0

Overview

R5F5631ECDBG#G0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 768 KB on-chip flash memory, 128 KB SRAM, and 32 KB data flash. It features a 12-bit A/D converter (21 channels), 10-bit D/A converter (2 channels), RTC, USB 2.0 function controller, CAN interface, and I²C/SCI/RSPI peripherals - designed for industrial control and networked embedded systems requiring deterministic real-time performance and functional safety support.

For engineers reviewing the R5F5631ECDBG#G0 datasheet, R5F5631ECDBG#G0 pinout, R5F5631ECDBG#G0 application, or R5F5631ECDBG#G0 equivalent, this page delivers verified specifications, package mapping to PLBG0176GA-A (13 × 13 mm, 0.8-mm pitch), confirmed peripheral channel counts per package, IEC60730-compliant self-test functions, and validated alternative MCUs for migration or second-sourcing.

Technical Context

The R5F5631ECDBG#G0 belongs to the RX631 Group - a subset of the RX63N/RX631 family differentiated by absence of Ethernet MAC and SDRAM controller. It implements the 32-bit RX CPU core with IEEE-754 single-precision FPU, 165 DMIPS @ 100 MHz, and CISC Harvard architecture with 5-stage pipeline and variable-length instructions.

It supports four low-power modes (sleep, all-module clock stop, software standby, deep software standby), operates from a single 2.7–3.6 V supply, and integrates MPU, JTAG/FINE debug interfaces, and hardware CRC calculator. Unlike RX63N variants, it omits Ethernet, EXDMAC, PDC, and sub-clock oscillator for battery backup.

FAQ

What is the maximum operating frequency and core performance of the R5F5631ECDBG#G0?

The R5F5631ECDBG#G0 operates at a maximum system clock frequency of 100 MHz. Its 32-bit RX CPU core delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit. The core supports variable-length instructions, 5-stage pipeline, and hardware multiplier/divider - enabling efficient execution of control algorithms and signal processing tasks in the R5F5631ECDBG#G0.

Does the R5F5631ECDBG#G0 include an Ethernet MAC or SDRAM controller?

No, the R5F5631ECDBG#G0 does not include an Ethernet MAC or SDRAM controller. It belongs to the RX631 Group, which is explicitly defined in the Renesas documentation as omitting these features present in the RX63N Group. This distinction reduces pin count, power consumption, and layout complexity - making the R5F5631ECDBG#G0 suitable for applications where Ethernet connectivity is unnecessary.

What package type and pin count does the R5F5631ECDBG#G0 use?

The R5F5631ECDBG#G0 uses the PLBG0176GA-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array with 13 mm × 13 mm body size and 0.8 mm ball pitch. This package supports 133 general-purpose I/O pins (including 18 5-V-tolerant), and is RoHS-compliant and lead-free. The R5F5631ECDBG#G0's pinout is fully documented in Renesas Application Note R01DS0098EJ0180.

Which communication interfaces are supported by the R5F5631ECDBG#G0?

The R5F5631ECDBG#G0 supports USB 2.0 function controller (full-speed), 3 CAN channels (ISO 11898-1 compliant, 32 mailboxes each), 4 I²C interfaces (one FM+ capable, up to 1 Mbps), 13 SCI channels (with LIN, SmartCard, SPI, and I²C emulation modes), 3 RSPI channels, and 1 IEBus channel. It does not support Ethernet, OTG, or host-mode USB - confirming its role as a peripheral-rich, non-networked controller.

Is the R5F5631ECDBG#G0 qualified for functional safety standards like IEC60730?

Yes, the R5F5631ECDBG#G0 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, independent watchdog timer (IWDT), self-diagnostic capability for the A/D converter, and clock frequency measurement circuitry. These are documented in the R01DS0098EJ0180 datasheet and enable certified firmware implementation without external safety monitors - a key advantage of the R5F5631ECDBG#G0 in safety-critical applications.
