Product details
Overview
R5F571MFDDFB#30 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip flash, 512 KB SRAM, 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, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MFDDFB#30 datasheet, R5F571MFDDFB#30 pinout, R5F571MFDDFB#30 application, or R5F571MFDDFB#30 equivalent, key selection criteria include dual Ethernet timing precision (IEEE 1588 PTP), hardware AES/SHA encryption support, 12-bit dual A/D converter channel count (29 total), and 177-pin TFLGA package compatibility with industrial PCB layout constraints.
Technical Context
The R5F571MFDDFB#30 implements the RXv2 core with single-cycle 32×32 multiplier, IEEE-754 FPU, and memory protection unit (MPU), enabling deterministic execution at 480 DMIPS. Its clock architecture separates ICLK (240 MHz CPU), PCLKA (120 MHz for Ethernet/USB/AES), and PCLKB (60 MHz for timers/ADC) domains to isolate real-time peripherals from system load.
It integrates dual Ethernet controllers with dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 timestamping), plus USBAa (high-speed USB 2.0 with 8.5 KB buffer) and USBb (full-speed) - all supported by hardware-accelerated crypto (AES-128/192/256, SHA-224/256, HMAC) and IEC60730 safety features including oscillation-stop detection and A/D self-diagnostic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDDFB#30 | Same RX71M family, identical 177-pin TFLGA package, but 2.5 MB flash (vs. 4 MB) and 384 KB SRAM (vs. 512 KB). | Suitable for cost-optimized gateways with smaller firmware footprint and reduced data buffering needs. | Select when full 4 MB flash and 512 KB SRAM are not required - lowers unit cost without changing PCB layout. |
| R5F572MFDDFB#30 | RX72M successor: higher 300 MHz CPU, enhanced Ethernet (TSN-ready), larger 8 MB flash, but different pinout and no USBAa high-speed USB. | Targeted at next-gen TSN-capable controllers where future-proofing justifies redesign and higher BOM cost. | Choose only if migrating to TSN and accepting new layout - not a drop-in replacement due to pinout and peripheral differences. |
Compared with R5F571MLDDFB#30, the R5F571MFDDFB#30 provides 1.5 MB more flash and 128 KB more SRAM for complex protocol stacks and local data caching; versus R5F572MFDDFB#30, it retains high-speed USB 2.0 and proven industrial qualification while offering lower entry cost and layout continuity.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MFDDFB#30?
The R5F571MFDDFB#30 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved using the RXv2 CPU core with single-cycle 32×32 multiplier and integrated IEEE-754 floating-point unit. The R5F571MFDDFB#30 maintains this performance across its full temperature range (–40°C to +105°C) with appropriate power supply decoupling and thermal management per the datasheet layout guidelines.
Does the R5F571MFDDFB#30 support IEEE 1588 Precision Time Protocol?
Yes, the R5F571MFDDFB#30 includes a dedicated PTP controller (EPTPCa) tightly coupled to both Ethernet MACs, enabling hardware timestamping of ingress/egress frames with sub-100 ns resolution. This allows the R5F571MFDDFB#30 to act as a transparent or boundary clock in time-sensitive networking applications - critical for synchronized motion control and distributed I/O systems.
How many CAN interfaces does the R5F571MFDDFB#30 provide, and what is the mailbox capacity per channel?
The R5F571MFDDFB#30 integrates three independent CAN modules (CAN0–CAN2), each compliant with ISO 11898-1 and supporting standard and extended frames. Each channel provides 32 dedicated mailboxes for prioritized message transmission and reception - enabling robust handling of mixed-criticality CAN traffic in automotive and industrial networks without CPU polling overhead.
What is the package type and pin count of the R5F571MFDDFB#30?
The R5F571MFDDFB#30 uses the PTLG0177KA-A package: a 177-pin TFLGA (Thin Fine-Pitch Land Grid Array) measuring 8 mm × 8 mm with 0.5 mm pitch and an exposed thermal pad. This compact, high-I/O-count package supports dense industrial PCB layouts while providing low-inductance grounding and thermal dissipation for sustained 240 MHz operation.
Does the R5F571MFDDFB#30 include hardware cryptographic acceleration?
Yes, the R5F571MFDDFB#30 includes dedicated hardware accelerators for AES (128/192/256-bit keys), DES/T-DES, SHA-1/224/256, and HMAC - all accessible via the CPG (Cryptographic Processor) module. These accelerators operate independently of the CPU, enabling secure boot, encrypted firmware updates, and TLS offload without impacting real-time task scheduling - a key requirement for R5F571MFDDFB#30 deployments in certified industrial systems.
