Overview
R5F571MFGDBG#20 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz max operating frequency, 4 Mbyte on-chip code flash, 512 Kbyte SRAM (including 32 Kbyte ECCRAM), IEEE 1588-compliant dual Ethernet MAC, and high-speed USB 2.0 with battery charging - designed for industrial gateway and real-time control applications requiring deterministic timing, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MFGDBG#20 datasheet, R5F571MFGDBG#20 pinout, R5F571MFGDBG#20 application, or R5F571MFGDBG#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), confirmed peripheral channel counts, real-time clock with battery backup, and functional alternatives for industrial Ethernet edge nodes.
Technical Context
The R5F571MFGDBG#20 implements the RXv2 CPU core with single-precision IEEE-754 FPU, 480 DMIPS performance at 240 MHz, and memory protection unit (MPU) support. It integrates dual Ethernet MACs with IEEE 1588 PTP hardware timestamping, EPTPC, and EDMAC with 3-channel DMA - enabling precise time-synchronized packet handling without CPU intervention.
Its clock system combines external crystal oscillator (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for independent domain clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC, USBA, AES), and PCLKB up to 60 MHz (for timers, ADC, SCI). The device supports four low-power modes and RTC operation from VBATT during deep software standby.

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDFB#20 | Same RX71M group, 176-pin LFBGA, but 2.5 Mbyte flash and 384 Kbyte SRAM; no USBAa (HS USB) module | Lacks high-speed USB 2.0 with battery charging; suitable for Ethernet-only gateways without peripheral device attachment | Select when cost sensitivity outweighs need for HS USB host capability and reduced flash/SRAM suffices |
| R5F572MHDFB#20 | RX72M group successor; same 176-pin LFBGA, 240 MHz, but adds 2D graphics accelerator, enhanced security (TRNG, RSA), and higher CAN FD bandwidth | Targets HMI-integrated controllers; includes GPU and CAN FD - not drop-in compatible due to peripheral register map changes | Choose for new designs requiring embedded GUI or CAN FD, but requires full firmware porting effort |
Compared with R5F571MFGDBG#20, R5F571MLDFB#20 reduces memory and removes HS USB while maintaining identical pinout and Ethernet capability, whereas R5F572MHDFB#20 introduces architectural enhancements that improve HMI and automotive-grade communication but require non-trivial migration effort.

FAQ
What is the maximum operating frequency and CPU performance of the R5F571MFGDBG#20?
The R5F571MFGDBG#20 operates at a maximum frequency of 240 MHz using the RXv2 CPU core and delivers 480 DMIPS of processing performance. Its single-precision IEEE-754 floating-point unit, dual MAC units, and 32-bit multiplier enable efficient signal processing and real-time control tasks. This performance level is validated in the official Renesas datasheet R01DS0249EJ0120 Rev.1.20.
Does the R5F571MFGDBG#20 support IEEE 1588 Precision Time Protocol?
Yes, the R5F571MFGDBG#20 includes dedicated hardware for IEEE 1588 compliance via the EPTPC (PTP Controller for Ethernet) module, which provides sub-microsecond timestamping accuracy on both Ethernet MAC channels. This enables precise time synchronization for industrial TSN applications without CPU load - a feature confirmed in the R01DS0249EJ0120 datasheet section 1.1 and Table 1.1.
What package type and pin count does the R5F571MFGDBG#20 use?
The R5F571MFGDBG#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Quad Flat Package (LFBGA) with 24 × 24 mm body size and 0.5-mm pitch. This matches the 176-pin configuration specified for RX71M devices with dual Ethernet and high-speed USB support, as documented in the Renesas datasheet R01DS0249EJ0120 Rev.1.20 on page 1.
How much on-chip memory does the R5F571MFGDBG#20 include?
The R5F571MFGDBG#20 integrates 4 Mbytes of code flash memory, 64 Kbytes of reprogrammable data flash (100,000 write/erase cycles), 512 Kbytes of general-purpose SRAM (with 256 Kbytes accessible at full 240 MHz speed), 32 Kbytes of ECCRAM with SEC-DED, and 8 Kbytes of standby RAM. These values are explicitly listed in Table 1.1 of the R01DS0249EJ0120 datasheet.
Is high-speed USB 2.0 supported on the R5F571MFGDBG#20?
Yes, the R5F571MFGDBG#20 includes the USBAa module supporting high-speed USB 2.0 (480 Mbps) host/function operation with battery charging capability - but only on 176- and 177-pin package variants. This is confirmed in the "Various communications interfaces" section of the R01DS0249EJ0120 datasheet, which specifies USBAa as available exclusively for those pin counts.
