Product details
Overview
R5F571MGHDBG#20 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 serves as a high-performance industrial control and connectivity hub in applications requiring real-time Ethernet, USB 2.0 HS with battery charging, CAN, and IEEE 1588 PTP timing.
For engineers reviewing the R5F571MGHDBG#20 datasheet, R5F571MGHDBG#20 pinout, R5F571MGHDBG#20 application, or R5F571MGHDBG#20 equivalent, key selection criteria include its 177-pin TFLGA package (8 × 8 mm, 0.5-mm pitch), G-grade temperature range (–40°C to +105°C), dual Ethernet MAC support, and hardware-accelerated AES/SHA encryption - all confirmed for this exact variant in Renesas Document R01DS0249EJ0120 Rev.1.20.
Technical Context
The R5F571MGHDBG#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates two independent Ethernet MAC modules (ETHERC) with IEEE 1588-compliant PTP controllers (EPTPC), each backed by dedicated EDMAC channels (3 total), and supports MII/RMII physical layer interfaces.
Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis - enabling independent domain clocks: ICLK up to 240 MHz (CPU), PCLKA up to 120 MHz (Ethernet, USB, AES), and PCLKB up to 60 MHz (timers, ADC, I²C). The device includes three CAN modules (ISO 11898-1 compliant, 32 mailboxes each) and dual USB modules: full-speed USBb (12 Mbps) and high-speed USBAa (480 Mbps) with battery charging support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLHDBG#20 | Same RX71M family, identical 177-pin TFLGA package and peripherals, but with 2.5 MB code flash (vs. 4 MB) and 384 KB SRAM (vs. 512 KB) | Suitable for cost-sensitive designs where reduced memory footprint suffices - e.g., simpler gateways without local web server or OTA update storage | Select when application firmware size remains under 2.5 MB and runtime heap requirements fit within 384 KB SRAM |
| R5F572MHDFB#20 | RX72M family successor: 240 MHz RXv3 core, 4 MB flash, 1 MB SRAM, enhanced security (TRNG, secure boot ROM), but 176-pin LFBGA (24 × 24 mm) - not pin-compatible | Targets next-gen designs requiring higher SRAM headroom, cryptographic acceleration, or longer product lifecycle; requires PCB redesign | Choose for new designs needing TRNG, secure boot enforcement, or >512 KB RAM; not a drop-in replacement due to package and pinout differences |

Does the R5F571MGHDBG#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F571MGHDBG#20 supports IEEE 1588 through its integrated EPTPC (PTP Controller for Ethernet) block, which is hardware-connected to both Ethernet MAC channels. Timestamping occurs at the MAC boundary with hardware-assisted correction for ingress/egress delays. The R5F571MGHDBG#20 provides dedicated registers for PTP clock synchronization, event message handling, and transparent clock functionality - enabling sub-microsecond time alignment essential for industrial motion control and synchronized measurement systems.

These resources are fully documented in the R5F571MGHDBG#20 datasheet (R01DS0249EJ0120) and enable complex protocol stacks, real-time buffering, and secure firmware storage without external memory.
Is the R5F571MGHDBG#20 pin-compatible with other RX71M variants, and what package does it use?
Yes, the R5F571MGHDBG#20 uses the PLQP0177KA-A (TFLGA-177) package - an 8 × 8 mm, 0.5-mm pitch fine-pitch land grid array - and shares identical pinout with all other 177-pin RX71M variants, including R5F571MLHDBG#20 and R5F571MKHDBG#20. This allows direct substitution within the same package family without PCB modification, provided memory and peripheral requirements align with the target variant's specifications.
What security features does the R5F571MGHDBG#20 offer for firmware protection and cryptographic operations?
The R5F571MGHDBG#20 includes optional hardware-accelerated cryptography (AES-128/192/256, DES/TDES, SHA-1/224/256), Trusted Memory blocks (8–9) that prevent unauthorized code readout, Memory Protection Unit (MPU) for runtime privilege enforcement, ECCRAM (32 KB) with SEC-DED error correction, and IEC 60730-compliant self-test functions (oscillation detection, CRC, A/D diagnostic).
