Product details
Overview
R5F571MJDDFC#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and dual 12-bit A/D converters - deployed in industrial gateways requiring deterministic real-time networking and secure firmware updates.
For engineers reviewing the R5F571MJDDFC#30 datasheet, R5F571MJDDFC#30 pinout, R5F571MJDDFC#30 application, or R5F571MJDDFC#30 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual Ethernet channel isolation, USB HS + FS coexistence, flash security (TM protection), and IEC60730 self-test compliance for functional safety certification.
Technical Context
The R5F571MJDDFC#30 implements the RXv2 CPU core with single-precision IEEE-754 FPU, two MAC units, and 5-stage CISC Harvard pipeline enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and EPTPC hardware-accelerated IEEE 1588 timestamping.
Clock architecture supports simultaneous operation at multiple domains: ICLK up to 240 MHz for CPU/SRAM, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals. Real-time clock (RTCd) operates from sub-clock oscillator with battery backup via VBATT, and independent watchdog (IWDTa) uses dedicated 120-kHz LOCO-derived clock with configurable window timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit, 240 MHz max, 480 DMIPS - enables real-time deterministic control with low-latency interrupt response (fast interrupt mode). |
| Memory | 4 MB code flash (no wait states ≤120 MHz), 512 KB SRAM (256 KB zero-wait @240 MHz), 64 KB data flash (100k write cycles) - supports background programming and secure firmware updates. |
| Ethernet | Dual IEEE 1588-compliant MAC (ETHERC) with MII/RMII, 10/100 Mbps full/half-duplex, Magic Packet/WOL - enables time-synchronized industrial networking without external PHYs. |
| USB | High-speed USB 2.0 host/function (480 Mbps) + full-speed USB 2.0 host/function (12 Mbps), both with OTG support and integrated transceivers - eliminates need for external USB PHYs in dual-role designs. |

Pinout & Package
LFBGA-176 package (PLQP0176KB-A), 24 × 24 mm, 0.5-mm pitch, with 127 general-purpose I/O pins (19 rated for 5-V tolerance), 1 dedicated reset (RES#), 1 VBATT for RTC backup, and dedicated power/ground pins for analog/digital domains and high-speed interfaces (Ethernet, USB, QSPI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES# | Active-low reset input | Drives chip into hard reset; synchronous release required for reliable initialization of all clock domains and peripherals. |
| VBATT | RTC backup supply | Enables continuous RTC operation during main VCC dropout; requires external coin-cell or supercap connection. |

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 |
|---|---|---|---|
| R5F571MLDDFC#30 | Same RX71M family, identical pinout and peripheral set, but with 2.5 MB code flash instead of 4 MB. | Suitable where firmware size < 2.5 MB and cost sensitivity outweighs future scalability needs. | Select when BOM cost reduction is critical and flash headroom is confirmed sufficient for full feature set + field updates. |
| R5F572MHDDFC#30 | RX72M family successor: higher 400 MHz CPU, enhanced security (TRNG, secure boot ROM), but no IEEE 1588 EPTPC or dual Ethernet MAC. | Better for AI-edge inference or advanced HMI; not drop-in for time-sensitive networking applications requiring PTP hardware. | Choose only if migrating to next-gen platform with different timing architecture; not a functional substitute for IEEE 1588 or dual Ethernet use cases. |
Compared with R5F571MJDDFC#30, the R5F571MLDDFC#30 offers identical real-time networking capability at lower flash capacity and cost, while the R5F572MHDDFC#30 trades IEEE 1588 and dual Ethernet for higher compute and stronger security - making the R5F571MJDDFC#30 uniquely suited for deterministic industrial time-sensitive networking.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MJDDFC#30?
The R5F571MJDDFC#30 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiplier, and dual MAC units. The R5F571MJDDFC#30 maintains this performance across its full temperature range (–40°C to +85°C) under specified voltage conditions (2.7–3.6 V).
Does the R5F571MJDDFC#30 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MJDDFC#30 includes the EPTPC (PTP Controller for Ethernet) block, which provides hardware-accelerated IEEE 1588 timestamping for both ingress and egress Ethernet frames. This enables sub-100 ns timestamp resolution and is tightly coupled with the dual ETHERC modules - a capability confirmed in the R01DS0249EJ0120 datasheet section 1.1 and Figure 1.1.
How many CAN modules does the R5F571MJDDFC#30 integrate, and what standard do they comply with?
The R5F571MJDDFC#30 integrates three independent CAN modules compliant with ISO 11898-1 (CAN v2.0B), each supporting standard and extended frames with 32 configurable mailboxes. This configuration is explicitly documented in the "Various communications interfaces" section of the R01DS0249EJ0120 datasheet and verified across all 176-pin RX71M variants including R5F571MJDDFC#30.
What is the flash memory configuration of the R5F571MJDDFC#30, and does it support background programming?
The R5F571MJDDFC#30 features 4 MB of on-chip code flash memory and 64 KB of reprogrammable data flash memory. Both support background programming/erasing (BGO), allowing application code execution during flash operations. The code flash has no wait states up to 120 MHz and one wait state above that - details confirmed in Table 1.1 and Section 1.1 of R01DS0249EJ0120.
Is the R5F571MJDDFC#30 pin-compatible with other RX71M group members such as R5F571MLDDFC#30?
Yes, the R5F571MJDDFC#30 is pin-compatible with R5F571MLDDFC#30 and other 176-pin LFBGA RX71M variants (e.g., R5F571MKDDFC#30). They share identical PLQP0176KB-A package, pin assignment, and peripheral signal mapping - enabling direct PCB reuse when migrating between flash capacities within the same package option, as stated in Table 1.2 of R01DS0249EJ0120.
