Product details
Overview
R5F571MFGDLJ#20 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, and dual 12-bit A/D converters - deployed in industrial gateways requiring real-time protocol stack execution, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MFGDLJ#20 datasheet, R5F571MFGDLJ#20 pinout, R5F571MFGDLJ#20 application, or R5F571MFGDLJ#20 equivalent, key selection criteria include IEEE 1588 PTP hardware timestamping accuracy, dual-channel Ethernet DMA channel allocation, 177-pin TFLGA package I/O count (127 general-purpose pins), and support for IEC60730 Class B functional safety diagnostics including CRC, oscillation-stop detection, and A/D self-test.
Technical Context
The R5F571MFGDLJ#20 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. Its clock architecture separates ICLK (up to 240 MHz), PCLKA (up to 120 MHz for Ethernet/USB/AES), and PCLKB (up to 60 MHz for timers/ADC) domains to optimize peripheral latency and power.
It integrates dual Ethernet controllers (ETHERC) with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC with 3 DMA channels (2 for ETHERC, 1 for EPTPC), plus USBAa supporting high-speed USB 2.0 (480 Mbps) with 8.5 KB on-chip buffer - all exclusive to 177-/176-pin variants like this part.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit core with 240 MHz max operation and 480 DMIPS performance - enables real-time deterministic control loops and protocol stack processing without external co-processors. |
| Memory | 4 MB code flash (no wait states ≤120 MHz), 512 KB SRAM (256 KB no-wait at 240 MHz), 64 KB data flash (100k write cycles) - supports background programming and secure firmware updates. |
| Ethernet | Dual IEEE 802.3 10/100 Mbps MAC with MII/RMII, IEEE 1588 PTP hardware timestamping, and 3-channel EDMAC - delivers sub-microsecond time synchronization for industrial automation. |

| Analog | Dual 12-bit S12ADC (8 + 21 channels), 0.48 µs conversion time, self-diagnostic and analog input disconnection detection - meets IEC60730 Class B requirements for safety-critical sensing. |
| Security | Optional AES-128/192/256, DES/T-DES, SHA-1/224/256, HMAC - enables secure boot, encrypted OTA updates, and cryptographic key storage in trusted memory blocks 8–9. |
| Package | 177-pin TFLGA (PTLG0177KA-A), 8 × 8 mm, 0.5 mm pitch, 127 GPIOs with 5-V tolerance on 19 pins - provides high-density routing for multi-interface industrial PCBs. |
Pinout & Package
Package: PTLG0177KA-A, 177-pin Thin Fine-Pitch Land Grid Array, 8 mm × 8 mm, 0.5 mm pitch, 0.75 mm height, RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, AVCC0, AVCC1 | Power supply inputs | Single 2.7–3.6 V supply domain for digital and analog sections; AVCC0/AVCC1 decoupling required for ADC reference stability. |
| VBATT | Battery backup supply | Enables RTC operation during main power loss; requires coin-cell or supercapacitor connection for deep software standby retention. |
| XTAL, EXTAL | Main crystal oscillator terminals | Supports 8–24 MHz external crystal for precise system clock generation; essential for IEEE 1588 PTP accuracy and USB timing compliance. |

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 |
|---|---|---|---|
| R5F571MLDFLJ#20 | Same RX71M family, identical 177-pin TFLGA package, but with 2 MB code flash (vs. 4 MB) and no USBAa high-speed USB module. | Suitable for cost-sensitive gateways without USB firmware update requirement; lacks hardware PTP timestamping support in EPTPC. | Select when dual Ethernet and IEEE 1588 are required but high-speed USB and full 4 MB flash are unnecessary. |
| R5F572MHDFLJ#20 | RX72M family successor; same 177-pin TFLGA, 240 MHz CPU, but adds 2D graphics accelerator, enhanced security (TRNG, secure boot ROM), and higher USB throughput (5 Gbps USB 3.0 capable). | Targets next-gen HMIs and edge AI inference; not pin-compatible due to different peripheral register mapping and voltage rail requirements. | Choose for future-proof designs needing graphics, AI acceleration, or stronger crypto; not a drop-in replacement. |
Compared with R5F571MLDFLJ#20, the R5F571MFGDLJ#20 provides double flash capacity and critical USBAa/IEEE 1588 features for secure, time-synchronized edge devices; versus R5F572MHDFLJ#20, it offers proven qualification and lower BOM cost where advanced graphics or USB 3.0 are unnecessary.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MFGDLJ#20?
The R5F571MFGDLJ#20 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 integrated single-precision IEEE-754 FPU. The R5F571MFGDLJ#20 sustains this performance across its full 4 MB code flash and 512 KB SRAM without wait-state penalties below 120 MHz.
Does the R5F571MFGDLJ#20 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MFGDLJ#20 includes a dedicated EPTPC (PTP Controller for Ethernet) block compliant with IEEE 1588-2008, enabling hardware-accelerated timestamping of Ethernet frames with sub-100 ns resolution. This capability is tightly coupled with its dual ETHERC modules and 3-channel EDMAC, allowing the R5F571MFGDLJ#20 to serve as a boundary clock or transparent clock in time-sensitive networking applications.

The R5F571MFGDLJ#20 integrates the USBAa module supporting high-speed USB 2.0 (480 Mbps) host/function operation with battery charging (BC1.2) compliance. It includes an on-chip transceiver and 8.5 KB RAM buffer, eliminating external PHY requirements. This feature is exclusive to 177-/176-pin RX71M variants - the R5F571MFGDLJ#20 is one of only two packages offering USBAa, alongside the 176-pin LFBGA.
How many analog-to-digital converter channels does the R5F571MFGDLJ#20 include, and what safety features are integrated?
The R5F571MFGDLJ#20 integrates two 12-bit S12ADC units: Unit 0 with 8 channels and Unit 1 with 21 channels, totaling 29 configurable analog inputs. Both units support self-diagnostic functions, analog input disconnection detection, and programmable sample-and-hold - all certified for IEC60730 Class B compliance. These features are integral to the R5F571MFGDLJ#20's safety architecture and require no external components.
What package type and pin count does the R5F571MFGDLJ#20 use, and is it pin-compatible with other RX71M variants?
The R5F571MFGDLJ#20 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array measuring 8 mm × 8 mm with 0.5 mm pitch. It is pin-compatible with the 176-pin LFBGA (PLBG0176GA-A) and LFQFP (PLQP0176KB-A) variants within the RX71M family, sharing identical signal assignments for power, clocks, Ethernet, USB, and major peripherals - enabling flexible PCB layout reuse across form factors.
