Product details
Overview
R5F5631EDDFC#V0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller with integrated FPU, 2 MB flash, 128 KB SRAM, and 32 KB data flash. It features 12-bit/10-bit ADCs (21/8 channels), dual 10-bit DACs, Ethernet MAC (not present), USB 2.0 host/function, 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 HMI and networked control systems requiring deterministic real-time performance without Ethernet PHY support.
For engineers reviewing the R5F5631EDDFC#V0 datasheet, R5F5631EDDFC#V0 pinout, R5F5631EDDFC#V0 application, or R5F5631EDDFC#V0 equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral channel counts per package, functional distinctions versus RX63N, and two rigorously cross-referenced alternative parts for cost- or feature-driven design trade-offs.
Technical Context
The R5F5631EDDFC#V0 implements the RXv1 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 and SRAM, plus background-programmable 32 KB data flash rated for 100,000 erase/write cycles.
Peripheral integration centers on deterministic real-time I/O: up to 134 GPIOs (18 × 5-V tolerant), 16-bit MTU2 and TPU timers (12+6 channels), 13 SCI interfaces with LIN/SmartCard modes, four I²C buses (1 × FM+), three RSPI channels, and dual CAN modules supporting 32 mailboxes each - all clocked via configurable PCLK dividers up to 50 MHz.

|---|---|
Use Scenario: Standalone touch-based operator interface with local logic, serial fieldbus connectivity, and analog sensor monitoring. IC Role / Device Role / Timing Role: Main application processor executing GUI rendering, real-time I/O scanning, and protocol stack (Modbus RTU/ASCII over SCI). Use Value: Integrated 12-bit ADC (21 ch), dual DACs, and 13 SCI ports eliminate external signal conditioning and UART expanders - reducing BOM count by ≥4 ICs. |
Use Scenario: DIN-rail mounted remote I/O node communicating via CANopen or RS-485 to central PLC, with local analog/digital signal acquisition. IC Role / Device Role / Timing Role: Deterministic real-time controller managing synchronized sampling of 16+ analog inputs and 8+ digital outputs at 1 kHz update rate. Use Value: MTU2/TPU timer resources provide hardware-synchronized ADC triggers and PWM outputs - ensuring sub-microsecond jitter for closed-loop control. |
| Medical Diagnostic Sensor Hub | Building Automation Gateway |
Use Scenario: Portable device aggregating signals from multiple biomedical sensors (ECG, SpO₂, temperature) and transmitting via USB to host PC. IC Role / Device Role / Timing Role: Signal acquisition and preprocessing engine with USB device-class firmware handling bulk transfers and HID reports. Use Value: On-chip USB 2.0 function controller + 2 KB buffer eliminates external PHY; temperature sensor and 12-bit ADC enable on-board calibration compensation. |
Use Scenario: BACnet/IP-to-BACnet MS/TP gateway bridging Ethernet backbone with legacy HVAC controllers over RS-485. IC Role / Device Role / Timing Role: Dual-role communication bridge: Ethernet MAC handled externally, while R5F5631EDDFC#V0 manages MS/TP framing, timing, and physical layer signaling via SCI. Use Value: 13 SCI channels allow concurrent management of multiple RS-485 segments and diagnostics port - avoiding multiplexer latency and contention. |
Equivalent & Alternatives

FAQ
Does R5F5631EDDFC#V0 include an Ethernet MAC controller?
No, R5F5631EDDFC#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC module. This distinguishes it from the RX63N Group (e.g., R5F563NEDDFC#V0), which integrates a full IEEE 802.3-compliant Ethernet controller with MII/RMII support. The R5F5631EDDFC#V0 datasheet confirms absence of ETHERC and EDMAC modules in Table 1.2.
What is the maximum operating frequency and associated performance metric for R5F5631EDDFC#V0?
R5F5631EDDFC#V0 operates at a maximum frequency of 100 MHz, achieving 165 DMIPS (Dhrystone 2.1) performance. This is enabled by its RXv1 CPU core with 5-stage pipeline, single-cycle 32-bit multiplier, and hardware floating-point unit compliant with IEEE-754 single-precision standard - all verified in Renesas document R01DS0098EJ0180 Section 1.1.
How many analog-to-digital converter channels does R5F5631EDDFC#V0 support, and what are their resolutions?
R5F5631EDDFC#V0 integrates two independent ADC units: a 12-bit S12ADa module with 21 input channels and a 10-bit ADb module with 8 input channels. Both support scan mode, sample-and-hold, and hardware-triggered conversion via MTU2/TPU/TMR - with 1.0 µs conversion time per channel at 50 MHz PCLK, as specified in R01DS0098EJ0180 pages 7 and 127.
Is R5F5631EDDFC#V0 pin-compatible with other members of the RX631 Group in the same package?
Yes, R5F5631EDDFC#V0 is fully pin-compatible with all RX631 Group devices in the PLQP0176KB-A (176-pin LQFP) package, including R5F563NECDFC#V0 and R5F563NEDDFC#V0. Pin definitions, power domains, and peripheral mappings are consistent across the group - confirmed in Table 1.2 of R01DS0098EJ0180, which shows identical I/O count (133 pins), 5-V tolerance (18 pins), and peripheral channel availability for 176-pin variants.
What debug interfaces are supported by R5F5631EDDFC#V0, and which emulators are compatible?
R5F5631EDDFC#V0 supports both JTAG and FINE (two-wire) debugging interfaces. It is compatible with Renesas E1 and E20 emulators - the E1 supporting full JTAG and FINE, and the E20 supporting JTAG-only operation. Debug functionality includes real-time trace, hardware breakpoints, and memory inspection, as documented in Section 1.1 and Appendix A of R01DS0098EJ0180.
