R5F571MFCDFC#V0 概要

The Renesas Electronics R5F571MFCDFC#V0 is a high-performance 32-bit RXv2 RX71M microcontroller IC running at 240 MHz with 2 MB of on-chip flash memory and 512 KB of SRAM, housed in a 176-pin LFQFP (24x24 mm) package for industrial-grade real-time control applications. It belongs to the Renesas RX Family RXv2 Instruction Set Architecture and integrates a rich set of peripherals including a Real-Time Engine (RTE) plus a Floating-Point Unit (FPU) for deterministic signal processing.

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.

主な用途

R5F571MFCDFC#V0 の用途: 6 件s: 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.

🏭

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.

🌐

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.

🧩

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.

🖥️

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.

⚡

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.

What is the operating CPU frequency of the R5F571MFCDFC#V0?
The R5F571MFCDFC#V0 runs the RXv2 core at up to 240 MHz. The on-chip PLL multiplies a system oscillator up to the core clock, and the flash access window is tuned to sustain single-cycle 32-bit fetches at that frequency. This 240 MHz rating places the RX71M at the top of the Renesas RX Family tree for industrial real-time control.
How much flash and SRAM does the R5F571MFCDFC#V0 have?
The R5F571MFCDFC#V0 integrates 2 MB of on-chip flash (2M x 8 organization) and 512 KB of SRAM on die. Both memories are accessible with zero wait-state bursts from the 240 MHz RXv2 core, eliminating the need for external instruction memory in most motor-control and PLC code footprints.
What package does the R5F571MFCDFC#V0 use and what are its dimensions?
The R5F571MFCDFC#V0 ships in a 176-LFQFP package measuring 24 mm by 24 mm with a 0.5 mm pitch. This is the largest LFQFP outline in the RX71M lineup and is intended for headroom-demanding industrial designs that route out an external 16-bit bus and bring out 298 peripheral interrupts.
Where can I download the R5F571MFCDFC#V0 datasheet PDF?
The official Renesas RX71M Group Datasheet (Group Rev.1.20) is hosted at https://www.renesas.com/en/document/dst/rx71m-datasheet-group-rev120 and the RX71M Group User's Manual: Hardware Rev.1.20 covers peripherals. Per the Renesas product page, you may also reference the RX Family RXv2 Instruction Set Architecture User's Manual for software details.
What is the difference between R5F571MFCDFC#V0 and R5F571MFCDFC#10?
The R5F571MFCDFC#V0 is the tray variant at 240 MHz with 2 MB flash, and the R5F571MFCDFC#10 from the same RX71M family uses a 144-LFQFP package with a smaller pinout. Pin counts and external bus widths differ, so the two cannot be a true drop-in swap - they target different board layouts within the same family.
What is the best drop-in replacement for the R5F571MFCDFC#V0?
Per the Renesas RX71M replacement part shown on the official product page, the recommended drop-in replacement is the R5F571MFCDFC#30, which is the full-carton version of the same 176-LFQFP silicon. Same-family memory-upsized variants such as R5F571MGCGFC#V0 also keep the 176-LFQFP footprint for engineering redundancy.
Where can I buy the R5F571MFCDFC#V0 online?
The R5F571MFCDFC#V0 is in distributor stock at DigiKey (link in data_sources), Mouser, and Octopart-listed distributors as of 2026-10-10. Expect pricing tiers as listed in this product page; for unbroken reels and full-cartons refer to the #30 variant per the Renesas product page replacement note.
Is the R5F571MFCDFC#V0 in stock and what is the lead time?
Per the DigiKey listing as of 2026-10-10, the R5F571MFCDFC#V0 ships today with the 'Buy now, ships today' indicator. For large OEM volumes, the manufacturer recommends the full-carton R5F571MFCDFC#30 variant for consistent supply; consult Mouser for an alternate distributor's lead-time estimate.
What is the price of the R5F571MFCDFC#V0 as of October 2026?
The R5F571MFCDFC#V0 lists at approximately 28.50 USD at quantity-1 on distributor sites as of 2026-10-10, decreasing toward 17.80 USD at qty-1000. Pricing reflects a high-performance 240 MHz industrial MCU and varies with reel vs tray configuration across DigiKey, Mouser, and Octopart.
R5F571MFCDFC#V0 vs R5F563NDCDFC#V0 - which is better for motor control?
Both run Renesas 32-bit cores, but the R5F571MFCDFC#V0 (RXv2 at 240 MHz, 2 MB flash) delivers higher core speed and larger code-storage than the R5F563NDCDFC#V0. For motor-control designs that need dense field-oriented control loops with Ethernet support, the RX71M is the stronger choice; for ultra-low-power sub-100 MHz tasks pick the RX563 variant.
R5F571MFCDFC#V0 vs R5F571MGCGFC#V0 - what is the difference?
Both parts share the RX71M core, 240 MHz speed, and 176-LFQFP footprint, but the R5F571MGCGFC#V0 is an upsized memory variant within the same family. Choose the MGCGFC when your firmware exceeds 2 MB flash; choose the R5F571MFCDFC#V0 for the 2 MB code space it is qualified to deliver.
Is the R5F571MFCDFC#V0 suitable for industrial PLC applications?
Yes, the R5F571MFCDFC#V0 is well-suited to industrial PLC platforms. With 2 MB flash for IEC 61131 runtime plus ladder logic, 512 KB SRAM for execution memory, eight CS areas for external I/O expansion, and 298 peripheral interrupt sources, the part meets the headroom demands of factory-automation controllers.
When should I choose the R5F571MFCDFC#V0 over a Cortex-M4 MCU?
Choose the R5F571MFCDFC#V0 when your industrial design needs 240 MHz deterministic performance, large on-chip flash (2 MB), an external 16-bit bus, and an 8-channel CS window unavailable on most Cortex-M4 parts. Pick a Cortex-M4 if your power budget or cost ceiling is lower and your firmware fits in less than 1 MB of flash.
What is the equivalent cross-brand part to the R5F571MFCDFC#V0?
There is no pin-exact cross-brand drop-in equivalent to the R5F571MFCDFC#V0 in the same 176-LFQFP footprint, since RXv2 cores, peripheral maps, and tool chains are Renesas-proprietary. The closest functional peers from other vendors are STM32 and Kinetis parts, which require both pinout remapping and firmware re-architecture.
Where do I find the R5F571MFCDFC#V0 pinout and package diagram?
The full 176-LFQFP pinout is documented in the Renesas RX71M Group User's Manual: Hardware Rev.1.20 (linked via the Renesas product page) and inside the RX71M Group Datasheet. The XAIPART product page also renders the package SVG via the package_svg_key 'lqfp-176' for a quick visual reference.

主な差別化要因

  • Replaces the R5F571MFCDFC#V0 exactly when buying full cartons (vs R5F571MFCDFC#30)
  • On-chip flash headroom for richer firmware footprints (vs R5F571MFDGFC#V0)
  • Larger SRAM for high-speed data-acquisition buffering (vs R5F571MJHDFC#V0)

設計ノート

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.
