Overview
R5F571MFHDFC#30 from Renesas is a 32-bit RXv2 microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and dual 12-bit A/D converters (8 + 21 channels). It targets industrial Ethernet gateway and real-time control applications requiring IEEE 1588 time synchronization, CAN, USB 2.0 HS with battery charging, and hardware encryption.
For engineers reviewing the R5F571MFHDFC#30 datasheet, R5F571MFHDFC#30 pinout, R5F571MFHDFC#30 application, or R5F571MFHDFC#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC with PTP support, 3-channel CAN, and support for IEC60730 functional safety compliance via built-in self-test features.
Technical Context
The R5F571MFHDFC#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dedicated clock domains: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers and communication interfaces.
Its memory subsystem includes 4 MB code flash with background programming/erasing (BGO), 64 KB data flash rated for 100,000 write/erase cycles, and segmented SRAM with differentiated wait-state behavior-zero-wait access for first 256 KB at 240 MHz, one-wait above 120 MHz for second 256 KB. The device supports endian selection and includes a 12-byte unique ID.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLHDFC#30 | Same RX71M group, identical 176-pin LFBGA package and core specs, but with 2.5 MB code flash (vs. 4 MB) and 384 KB SRAM (vs. 512 KB) | Suitable for cost-sensitive designs where firmware footprint <2.5 MB and RAM usage <384 KB; lacks capacity for dual Ethernet stack + full crypto suite | Select when application firmware size and runtime memory demand are confirmed below 2.5 MB/384 KB thresholds |
| R5F572MHDFC#30 | RX72M series successor: higher 400 MHz CPU, 8 MB flash, enhanced security (TRNG, secure boot ROM), but no IEEE 1588 PTP hardware-relies on software timestamping | Better for AI-edge inference or larger HMI applications; unsuitable for sub-microsecond time-critical Ethernet synchronization | Choose only if PTP hardware timestamping is not required and higher CPU throughput justifies migration effort and cost premium |

The R5F571MFHDFC#30 maintains this performance across its full voltage range (2.7–3.6 V) and temperature range (–40°C to +85°C).
Does the R5F571MFHDFC#30 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MFHDFC#30 includes a dedicated PTP controller (EPTPCa) tightly coupled to both Ethernet MAC modules, enabling hardware-accelerated timestamping of ingress and egress Ethernet frames with sub-microsecond resolution. This allows the R5F571MFHDFC#30 to serve as a boundary clock or transparent clock in time-sensitive networking applications without CPU intervention.
How many CAN modules does the R5F571MFHDFC#30 integrate, and what is the mailbox capacity per channel?
The R5F571MFHDFC#30 integrates three independent CAN modules (CAN0, CAN1, CAN2), each supporting 32 configurable mailboxes for message filtering and buffering. Each mailbox supports standard (11-bit) and extended (29-bit) frame formats per ISO 11898-1, and the R5F571MFHDFC#30 supports bit rates up to 1 Mbps with programmable sample points and synchronization jump width.
What is the flash and SRAM configuration of the R5F571MFHDFC#30?
The R5F571MFHDFC#30 features 4 MB of on-chip code flash memory with zero-wait-state access up to 120 MHz and background programming/erasing capability, plus 64 KB of reprogrammable data flash rated for 100,000 write/erase cycles. Its RAM consists of 512 KB general-purpose SRAM (with segmented wait-state behavior), 32 KB ECC-protected RAM (SEC-DED), and 8 KB battery-backed standby RAM.
Is the R5F571MFHDFC#30 qualified for IEC60730 Class B functional safety applications?
Yes, the R5F571MFHDFC#30 includes multiple hardware features supporting IEC60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculation unit, independent watchdog timer (IWDTa) with windowed refresh, self-diagnostic function for the A/D converter, and register write protection for critical control registers.
