MPN: R5F5631MCDFL#V0 ✓ פעילR5F5631MCDFL#V0 סקירה
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a wide range of on-chip peripherals. The RX631 family sits in the hierarchy RXv1 core -> RX600 family -> RX series -> 32-bit MCU -> embedded microcontroller -> semiconductor, positioning the device between low-end 8/16-bit MCUs and application processors. It excels in deterministic real-time control with single-cycle multiply-accumulate, hardware FPU optional, and built-in safety features such as memory protection, register write protection, and an on-chip watchdog.
Differentiating features of R5F5631MCDFL#V0 include 100 MHz core speed delivering 235 DMIPS, on-chip 4 KB data Flash for EEPROM emulation, dual 12-bit ADC units up to 1 MSPS each, 16-bit timer pulse units supporting motor-control PWM, up to 14 communication interfaces including CAN (1 channel), USB 2.0 host/function, Ethernet MAC, I2C, RSPI, and SCI. The block diagram emphasizes energy-efficient operation with low-power run/standby modes, RTC with calendar, and a temperature sensor interface. Direct-memory-access controllers (DMAC/DTC) reduce CPU overhead for data movement between peripherals and memory.
Technically, the RXv1 core is a 5-stage pipelined RISC architecture with Harvard-style bus structure and hardware integer multiplier/divider, providing high code density and predictable interrupt latency. The on-chip Flash uses single-cycle flash-IO for wait-state-free 100 MHz fetch. Analog integration includes 8x 12-bit ADC inputs at 1 MSPS, two 10-bit DAC channels, and a comparator that supports motor-control feedback loops. The safety suite contains IEC 60730 Class B support with hardware CRC, ILLEGAL address detection, and a register-write-protect function for safety-critical firmware integrity.
Typical applications for R5F5631MCDFL#V0 include industrial motor-control inverters, factory-automation PLCs, networked sensor nodes, embedded medical instrumentation, building-automation controllers, and CAN-based automotive body modules. The combination of Ethernet+CAN+USB makes the device a fit for industrial IoT gateways where several field buses must be terminated by a single low-power 32-bit MCU running an RTOS or bare-metal scheduler.
When designing with this MCU, the 3.3V rail should be decoupled with at minimum one 0.1 uF X7R ceramic per VDD/VSS pair. The integrated Ethernet MAC still requires an external PHY and magnetics. JTAG/finbd footprint are 14-pin, 0.5 mm pitch for programming and debug.

יישומים טיפוסיים
R5F5631MCDFL#V0 מתאים עבור 7 יישוםs: Industrial Motor Control Inverter, Industrial IoT Gateway with CAN/Ethernet/USB, Building Automation HVAC Controller, CAN-Based Automotive Body Module, Embedded Medical Instrumentation, Factory-Automation PLC and Sensor Hub, Networked Sensor Node / Smart City Edge.
Industrial Motor Control Inverter
The R5F5631MCDFL#V0 fits industrial motor-control inverters thanks to its 100 MHz RXv1 core and 16-bit timer pulse units that drive three-phase complementary PWM at sub-microsecond resolution. The 12-bit ADC sampling at 1 MSPS per unit captures dual-shunt current feedback for field-oriented control, and the on-chip CAN interface lets the drive publish position and torque telemetry. Field-oriented control loops run inside 16 microseconds at 100 MHz core, leaving headroom for software state machines. Real-time deterministic interrupt latency of 5 cycles on RXv1 helps maintain switching accuracy even under heavy bus traffic.
מומלץ
Industrial IoT Gateway with CAN/Ethernet/USB
Industrial IoT gateways benefit from R5F5631MCDFL#V0's triple-protocol connectivity - CAN for plant-floor networks, Ethernet MAC for IT/OT bridge, and USB 2.0 Host/Function for diagnostics or Wi-Fi dongles. With 64 KB SRAM, the device can hold lightweight TCP/IP stacks and a CANopen or Modbus RTU parser concurrently. The 256 KB Flash fits application firmware plus OTA staging buffers. Hardware DMA (DMAC + DTC) offloads bulk packet movement, keeping the CPU free for protocol translation. Watchdog and IEC-60730 Class B features support safety-compliant cloud-edge devices.
מומלץ
Building Automation HVAC Controller
Building-automation HVAC controllers use the R5F5631MCDFL#V0 for distributed I/O handling across fan-coil units, variable-refrigerant-flow systems and thermostats. The 12-bit ADC reads thermistor bridges, the 16-bit timer pulse units drive triac-controlled AC loads, and SCI/RSPI daisy-chain the controller to indoor units. Three UART channels let the MCU serve as a Modbus RTU master while simultaneously logging energy data to a host. Low-power standby current of a few microamps extends battery life in wireless sensors paired with the MCU.
מומלץ
CAN-Based Automotive Body Module
CAN-based automotive body modules use the R5F5631MCDFL#V0's hardware CAN interface together with the 12-bit ADC to read seat-occupancy sensors, mirror-position encoders and lighting drivers. The 100 MHz RX core cycles through CAN message parsing within tight in-vehicle network windows (typically under 10 ms). The watchdog and CRC peripheral provide ISO 26262 entry-level support, while the integrated RTC with calendar drives periodic wake-up for body-control functions. The 48-pin LFQFP package sits comfortably on small body-control PCBs.
מומלץ
Embedded Medical Instrumentation
Embedded medical instrumentation leverages the R5F5631MCDFL#V0's deterministic 100 MHz execution and 12-bit ADC at 1 MSPS for patient-monitoring peripherals such as pulse-oximetry, ECG front-ends and infusion pumps. The 4 KB data Flash stores calibration constants and device serial numbers without external EEPROM, while SRAM buffers waveform samples before transmission over USB or Ethernet. Hardware CRC and IEC 60730 safety features support regulatory-grade designs. Operating voltage of 3.3V simplifies battery-powered portable designs.
מומלץ
Factory-Automation PLC and Sensor Hub
Programmable logic controllers (PLCs) and sensor hubs use the R5F5631MCDFL#V0 as the central processor for digital and analog I/O handling. The 12-bit ADC reads 4-20 mA current loops through external resistors, while the digital timers debounce and count high-speed encoder signals. SCI/RSPI ports expand the I/O count by daisy-chaining shift registers or external ADC chips. The integrated Ethernet MAC provides Modbus TCP connectivity for SCADA networks without a companion controller. Security features like register write-protect prevent unauthorized firmware tampering in industrial environments.
מומלץ
Networked Sensor Node / Smart City Edge
Networked sensor nodes for smart-city edge devices use the R5F5631MCDFL#V0 with its Ethernet MAC for long-range wired backhaul and CAN/RSPI for local sensor aggregation. The 256 KB Flash stores TLS handshake material, while 64 KB SRAM holds compressed sensor frame buffers. Multiple low-power standby modes allow battery-powered deployment in lamp-posts, parking sensors, and environmental-quality monitors. The RXv1 deterministic interrupt controller guarantees sub-100-microsecond response to CAN emergency frames even when servicing an Ethernet stack.

הערות תכנון
Decouple the R5F5631MCDFL#V0 with one 0.1 uF X7R ceramic capacitor on every VDD/VSS pin pair and one 10 uF bulk capacitor on AVCC plus one 4.7 uF on VCL within 5 mm of the package. The internal core LDO from VCL must see low impedance to avoid dropout during high-frequency CPU bursts. Add a ferrite bead on the analog AVCC rail if switching noise from companion converters exceeds 50 mVpp - this isolates the 12-bit ADC reference during motor current sampling. Estimated: at 100 MHz core active current ~ 30 mA, the bulk cap prevents inrush brown-out over -40C startup.
Route the analog ADC traces (AN000-AN007) over a single unbroken ground reference plane, away from switching nodes such as the motor PWM outputs TMO0/TMO1 or the USB D+/D- differential pair. Keep trace length under 25 mm and place guarding ground vias every 200 mil to maintain ADC sample integrity. The 48-LFQFP exposes the analog pins on pin 4-11 forming a contiguous bus - a convenient layout for a 4-layer stack-up with L2 as solid ground plane.
Do not drive any I/O pin beyond 3.6V absolute maximum even if a 5V peripheral is present - the RX631 GPIO is NOT 5V tolerant. If you must interface to 5V signals, use the on-chip SCI levels plus an external level shifter. Also, leave the unused analog pins ANx in input-disabled state (PDR=0, PMR=0) and add ADC software filters for noise robustness; floating analog pins can cause ADC conversion drift on adjacent channels. Estimate: at room temperature, floating ANx pin drift adds 1-2 LSB noise to the disabled ADC register.
The LFQFP-48 package is rated to thermal resistance theta_JA ~ 60 C/W on a standard JEDEC 4-layer test PCB. At full 100 MHz CPU activity (~ 30 mA) the device dissipates roughly 100 mW, yielding a junction temperature rise of about 6 C above ambient - well within the 85 C industrial limit. For applications operating near 85 C ambient, derate CPU utilisation to 70% to maintain reliability margin. Always reference the manufacturer datasheet for definitive thermal numbers; estimated dissipation should be confirmed before system thermal budgets are finalised.
