R5F571MFCDFC#V0 - RX71M 240MHz 32-bit MCU 2MB Flash | Renesas
MPN: R5F571MFCDFC#V0 ✓ פעילR5F571MFCDFC#V0 סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, peripherals, and interrupt logic into one IC. The RXv2 core is a proprietary Renesas CPU superset that combines the performance of a 32-bit pipeline with deterministic interrupt response, targeting motor control, factory automation, and networked industrial equipment. The RX71M sits at the top of the RX Family, where the broader hierarchy runs: RX71M -> RX71x -> RX Family -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. This position signals that the part is engineered for headroom-demanding, real-time industrial platforms with large code footprints.
Key features of the R5F571MFCDFC#V0 include 240 MHz core speed, 2 MB flash, 512 KB SRAM, a 16-bit external bus with up to eight chip-select areas (CS0 to CS7), up to 298 peripheral interrupt sources, and a hardware crypto accelerator. A built-in RTC with VBATT domain allows retention through main VCC dropouts, and the 176-LFQFP package provides enough pins for parallel bus, multiple UART, I2C, SPI, CAN, and analog channels needed in industrial designs.
The RXv2 CPU uses a Harvard-style five-stage pipeline with hardware multiply/divide and a single-precision FPU. On-chip flash is configured as 2M x 8, supporting in-system programming and background operation. The device accepts a 3.3 V supply per industrial distribution lines, and at 240 MHz it sustains CPU-intensive signal-processing workloads with predictable worst-case interrupt latency.
Typical applications include motor control and inverter drives, PLC and industrial controllers, networked factory automation nodes, building control systems, and high-speed data acquisition equipment. Engineers select the RX71M when their design needs abundant flash, deterministic real-time response, and the legacy footprint of a 176-pin industrial MCU.
When laying out the PCB, dedicate copper directly under the exposed die-attach pad to the ground plane for thermal spreading, and keep the analog AVCC/VREF decoupling network within 10 mm of the dedicated supply pins. Use the eight CS areas to map external SRAM, NOR flash, and peripheral expansion without external glue logic.

יישומים טיפוסיים
R5F571MFCDFC#V0 מתאים עבור 6 יישוםs: Industrial Motor Control and Inverters, Programmable Logic Controllers (PLC), Factory Automation and Industrial Ethernet, Building Automation and HVAC Controllers, High-Speed Data Acquisition Equipment, Renewable Energy Inverters (Solar / Energy Storage).
Industrial Motor Control and Inverters
The R5F571MFCDFC#V0 is engineered for industrial motor control, where the 240 MHz RXv2 core drives field-oriented control (FOC) loops in the tens of microseconds. The 2 MB flash hosts sensorless vector control libraries plus state machines, while 512 KB SRAM buffers PWM timer arrays and ADC scan results without bus contention. The 176-LFQFP package exposes the external 16-bit bus to attach encoder interfaces and resolver-to-digital converters, and the eight CS areas let you map multiple SRAM banks for current-loop execution memory.
מומלץ
Programmable Logic Controllers (PLC)
In PLC platforms, the R5F571MFCDFC#V0 serves as the central scan engine, executing IEC 61131 runtimes and ladder logic at the 240 MHz core clock. The 2 MB flash stores ladder programs plus diagnostic libraries, and 512 KB SRAM holds runtime tag tables for thousands of I/O points. The eight CS areas partition external I/O modules, and the 298 peripheral interrupt sources absorb high-speed digital event streams from distributed I/O backplanes.
מומלץ
Factory Automation and Industrial Ethernet
For networked factory devices the R5F571MFCDFC#V0 runs Ethernet/IP, PROFINET, or EtherCAT slave stacks while continuing to handle real-time control loops on the same chip. The 240 MHz core headroom supports both TCP/IP processing and deterministic motion control, and the 2 MB flash holds multiple protocol stacks simultaneously. The VBATT-backed RTC lets the node maintain time sync through power events, while the 176-LFQFP pin count absorbs PHY, PHY-clock, and isolated serial interfaces.
מומלץ
Building Automation and HVAC Controllers
In building automation, the R5F571MFCDFC#V0 manages HVAC actuators, BACnet/Modbus gateways, and on-board graphical touch interfaces. The 2 MB flash holds BACnet stacks plus UI firmware, while 512 KB SRAM supports multi-zone scheduling tables and trend logs. The 176-LFQFP package provides enough pins to drive keypads, displays, and multiple UART links to VAV and AHU controllers concurrently.
מומלץ
High-Speed Data Acquisition Equipment
The R5F571MFCDFC#V0 acts as a buffered front-end for industrial data-acquisition systems, where the 240 MHz core ingests ADC samples from DMA channels and runs decimation filters in real time. The 512 KB SRAM buffers acquisition bursts before the host reads them, while the 2 MB flash stores calibration tables and DSP algorithms for vibration, strain, or power-quality analysis.
מומלץ
Renewable Energy Inverters (Solar / Energy Storage)
For solar inverters and energy storage systems, the R5F571MFCDFC#V0 acts as the main controller executing MPPT loops, grid-synchronization code, and protection logic. The 240 MHz RXv2 core plus hardware FPU keeps vector math responsive; the 2 MB flash stores firmware plus grid-code tables for multiple regional certifications; and the 176-LFQFP package accesses gate-driver and isolation channels with sufficient I/O.

הערות תכנון
Place a 1.0 uF X7R ceramic bypass within 5 mm of every VCC pin and a 10 uF bulk capacitor at the regulator output feeding the MCU. Use a 10 uH bead plus 100 nF cap on the VBATT pin to filter battery noise; populate both VCC rails independently even though the IC has two VCC pins on different packages segments.
Estimated: at 240 MHz with all peripherals enabled the part dissipates approximately 0.4-0.6 W internally on a typical industrial workload; the 176-LFQFP with a 4-layer 100x100 mm PCB yields roughly 25 C/W theta-JA, so at 0.5 W expect ~12.5 C rise. For sealed IP65 enclosures, derate clock during high ambient to maintain junction below 105 C.
Route the external data bus D0-D15 with matched-length traces within 0.5 mm tolerance to avoid bus skew at 75 MHz. Place the SDRAM/SRAM chip-select lines CS0#/CS7# in dedicated layers with 33 ohm series damping, and keep the EXTAL/ XTAL traces within 3 mm of the crystal with a grounded shield ring.
Differential pair routing: route USB0_DP/USB0_DM as a 90-ohm differential pair with no stubs to the connector, and route Ethernet MII signals with 50-ohm impedance to the magnetics module. AVCC/VREFH/VREFL traces must be guarded by AVSS copper pours to suppress ADC reference noise by at least 10 dB.
Do not leave the EMLE pin floating during production - tie EMLE to VCC through a 10 kohm resistor to enter boundary-scan mode only intentionally. The MD pin determines boot mode; sampling of MD at the rising edge of RES# selects the boot vector between single-chip and serial programming. Leaving the sub-clock oscillator inputs floating with no crystal will cause spurious interrupt sources.
