Product details
Overview
R5F571MGHDFP#30 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip code 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 firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MGHDFP#30 datasheet, R5F571MGHDFP#30 pinout, R5F571MGHDFP#30 application, or R5F571MGHDFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, real-world use cases in time-sensitive networking, and two validated alternative MCUs for migration or sourcing flexibility.
Technical Context
The R5F571MGHDFP#30 implements the RXv2 core with 480 DMIPS at 240 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units - enabling real-time signal processing in motor control and audio applications. It integrates a memory protection unit (MPU), JTAG/FINE debug interfaces, and supports little- or big-endian data arrangement.
Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated), with independent clock domains: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet/USB/AES), and PCLKB up to 60 MHz (for timers/ADC). The device includes three independent watchdogs (WDTA, IWDTa, and RTC-based) and voltage monitoring across three levels for IEC 60730 Class B 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 |
|---|---|---|---|
| R5F571MLHDFP#30 | Same RX71M family, identical 176-pin LFBGA package, but with 2.5 MB code flash and 384 KB SRAM - lower memory capacity, same peripheral set and clock performance. | Suitable for cost-optimized gateways where full 4 MB flash is unnecessary; retains dual Ethernet, USB HS, and CAN. | Select when BOM cost reduction is prioritized and firmware image size remains under 2.5 MB. |
| R5F572MHGFP#30 | RX72M family successor: 240 MHz RXv3 core, 4 MB flash, 1 MB SRAM, enhanced security (TRNG, secure boot ROM), but 176-pin LQFP (not LFBGA) and no high-speed USB - different package and reduced USB capability. | Better suited for next-gen secure controllers requiring TRNG and larger RAM; not drop-in due to LQFP vs LFBGA and missing USB HS PHY. | Choose for long-term design-in where security certification (e.g., PSA Level 2) and future-proofing outweigh PCB layout reuse. |
Compared with R5F571MGHDFP#30, R5F571MLHDFP#30 offers identical pinout and peripherals at reduced memory cost, while R5F572MHGFP#30 upgrades core architecture and security but requires board redesign due to LQFP packaging and lacks USB 2.0 high-speed transceiver - making the former ideal for footprint-compatible scaling down, and the latter for security-driven generational upgrade.
