For engineers reviewing the R5F571MFHGFP#V0 datasheet, R5F571MFHGFP#V0 pinout, R5F571MFHGFP#V0 application, or R5F571MFHGFP#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional pin roles, real-world use cases, and two validated alternative MCUs - all grounded in Renesas R01DS0249EJ0120 Rev.1.20 documentation.

Technical Context

The R5F571MFHGFP#V0 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPCa and dedicated EDMACa (3-channel DMA), enabling time-synchronized packet timestamping and low-CPU-load frame handling.

Its memory subsystem includes 4 MB code flash with zero-wait access ≤120 MHz and background programming, 64 KB data flash rated for 100,000 erase/write cycles, 512 KB SRAM (256 KB zero-wait at 240 MHz), and 32 KB ECCRAM with SEC-DED error correction - optimized for safety-critical industrial firmware and runtime data integrity.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MFHGFP#V0?

The R5F571MFHGFP#V0 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, variable-length instruction set, and integrated 32-bit multiplier executing instructions in one cycle. The R5F571MFHGFP#V0 sustains this performance with zero-wait-state access to code flash up to 120 MHz and efficient cache-like AFU hit behavior at 240 MHz.

Does the R5F571MFHGFP#V0 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MFHGFP#V0 supports IEEE 1588 via its integrated EPTPCa (PTP Controller for Ethernet Controller), which is hardware-connected to both ETHERC modules. It provides hardware timestamping of ingress/egress Ethernet frames, PTP message parsing, and synchronization with MTU3/GPT timers - enabling sub-microsecond time accuracy in industrial TSN applications without CPU intervention.

What package type and pin count does the R5F571MFHGFP#V0 use?

The R5F571MFHGFP#V0 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm footprint and 0.5-mm pitch. This package supports all RX71M peripherals including dual Ethernet, USB HS, CAN, and 127 general-purpose I/O pins with 5-V tolerance on 19 pins - confirmed in Renesas document R01DS0249EJ0120 Rev.1.20, Table 1.2.

How much on-chip flash and SRAM does the R5F571MFHGFP#V0 include?

The R5F571MFHGFP#V0 integrates 4 MB of on-chip code flash memory and 512 KB of SRAM. The flash supports background programming/erasing (BGO) and zero-wait access up to 120 MHz. The SRAM is partitioned into 256 KB (0000_0000h–0003_FFFFh) with zero-wait access at 240 MHz, and another 256 KB (0004_0000h–0007_FFFFh) with zero-wait access up to 120 MHz - all verified in the R5F571MFHGFP#V0 datasheet Section 1.1.

Is hardware encryption available on the R5F571MFHGFP#V0?

Yes, the R5F571MFHGFP#V0 includes optional hardware-accelerated encryption: AES (128/192/256-bit), DES/T-DES, and SHA-1/SHA-2 (224/256)/HMAC. These modules operate independently of the CPU, enabling secure boot verification, firmware signature checking, and TLS handshake acceleration - critical for industrial gateway security compliance per IEC 62443.
