Product details
Overview
R5F571MFCGFP#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS and integrated single-precision IEEE-754 FPU. It integrates 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), dual 12-bit ADCs (29 total channels), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring deterministic real-time control and secure network edge processing.
For engineers reviewing the R5F571MFCGFP#V0 datasheet, R5F571MFCGFP#V0 pinout, R5F571MFCGFP#V0 application, or R5F571MFCGFP#V0 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB HS + CAN triple-protocol connectivity, 240-MHz real-time execution, hardware AES/SHA crypto acceleration, and IEC 60730 safety support for certified embedded systems.
Technical Context
The R5F571MFCGFP#V0 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling ultra-compact code and deterministic interrupt latency down to 5 CPU cycles. Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and independent 240-kHz LOCO/HOCO sources, with fully configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Real-time data movement is handled by three dedicated DMA subsystems: 8-channel DMAC, 2-channel EXDMAC, and 3-channel EDMAC for Ethernet - each supporting descriptor-based transfers, block/repeat modes, and event-linking via ELC. The MCU supports simultaneous IEEE 1588 timestamping across both Ethernet channels using the EPTPC module synchronized to MTU3/GPT timers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDFP#V0 | Same RX71M family, identical 177-pin TFLGA package, but with 2 MB code flash and 256 KB SRAM - lower memory density. | Suitable for cost-optimized gateways where 4 MB flash and 512 KB SRAM are not required. | Select when BOM cost reduction is prioritized over future firmware scalability and large buffer requirements. |
| R5F572MLHFP#V0 | RX72M family successor: 240 MHz RXv3 core, 4 MB flash, 1 MB SRAM, enhanced EtherCAT slave support, but no USB HS PHY - different pinout (176-LFBGA). | Targeted at next-gen motion controllers requiring EtherCAT slave stack and larger RAM for complex trajectory planning. | Choose only if migrating to RXv3 architecture and accepting PCB redesign; not pin-compatible with R5F571MFCGFP#V0. |

The R5F571MFCGFP#V0 includes two fully independent IEEE 802.3-compliant Ethernet MAC interfaces (ETHERC), each supporting 10/100 Mbps operation in full- or half-duplex mode with MII or RMII physical layer interfaces. Both MACs are paired with dedicated EDMAC channels and share access to the EPTPCa PTP engine - enabling dual-network redundancy or protocol segregation (e.g., one port for control traffic, one for diagnostics) in systems built around R5F571MFCGFP#V0.
Is hardware cryptographic acceleration available on the R5F571MFCGFP#V0?
Yes, the R5F571MFCGFP#V0 includes optional hardware crypto acceleration supporting AES-128/192/256, DES/TDES, and SHA-1/224/256 with HMAC.
