Renesas R5F571MGHGFP#V0

Overview

R5F571MGHGFP#V0 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 networked edge devices requiring real-time Ethernet, USB HS, CAN, and SD host support.

For engineers reviewing the R5F571MGHGFP#V0 datasheet, R5F571MGHGFP#V0 pinout, R5F571MGHGFP#V0 application, or R5F571MGHGFP#V0 equivalent, this MCU is evaluated for deterministic real-time control, IEC 60730-compliant safety functions, IEEE 1588 time synchronization, and multi-interface coexistence in space-constrained industrial gateways and motor drives.

Technical Context

The R5F571MGHGFP#V0 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and 512 KB SRAM partitioned into no-wait regions (0–256 KB at 240 MHz) and wait-state-sensitive zones (256–512 KB above 120 MHz).

Peripheral integration centers on deterministic timing and protocol offload: dual IEEE 1588-compliant Ethernet MACs (176-/177-pin variants), one high-speed USB 2.0 module with battery charging support, three CAN modules (32 mailboxes each), and parallel data capture for CMOS camera interfaces - all coordinated via the Event Link Controller (ELC) to minimize CPU intervention.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MGHGFP#V0?

The R5F571MGHGFP#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through its optimized RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and integrated single-precision IEEE-754 floating-point unit. The R5F571MGHGFP#V0 maintains this performance across its full voltage range (2.7–3.6 V) and temperature range (–40°C to +105°C).

Does the R5F571MGHGFP#V0 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MGHGFP#V0 includes a dedicated PTP controller (EPTPCa) compliant with IEEE 1588-2008. It provides hardware timestamping for Ethernet frames with sub-microsecond resolution, enabling precise time synchronization in industrial Ethernet networks. The R5F571MGHGFP#V0 supports both one-step and two-step clock correction modes and integrates tightly with its dual Ethernet MACs for deterministic latency handling.

How many A/D converter channels does the R5F571MGHGFP#V0 provide, and what are their key specifications?

The R5F571MGHGFP#V0 integrates two independent 12-bit A/D converters: S12ADC unit 0 with 8 channels and unit 1 with 21 channels. Conversion time is 0.48 µs per channel at 12-bit resolution, with selectable 8/10/12-bit modes. Both units support scan modes, group priority control, sample-and-hold (including channel-dedicated for 3 channels in unit 0), and self-diagnostic functions. The R5F571MGHGFP#V0 uses separate ADCLK domains (PCLKC/PCLKD) for optimal timing control.

What USB capabilities does the R5F571MGHGFP#V0 offer, and which variants support high-speed operation?

The R5F571MGHGFP#V0 includes two USB modules: USBb (full-speed/low-speed) and USBAa (high-speed/full-speed/low-speed). High-speed (480 Mbps) operation is supported only on 176- and 177-pin packages-including the R5F571MGHGFP#V0 in LFBGA-176-via its integrated USBAa transceiver. The R5F571MGHGFP#V0 also supports USB OTG, battery charging detection (BC1.2), and requires no external pull-up/pull-down resistors.

Is the R5F571MGHGFP#V0 pin-compatible with other RX71M Group MCUs?

Yes, the R5F571MGHGFP#V0 in LFBGA-176 (PLQP0176KB-A) is pin-compatible with other RX71M devices in the same package variant, including R5F571MLHDFP#V0 and R5F571MHGFP#V0. Pin assignments for power, reset, clocks, Ethernet, USB, CAN, and major peripherals are identical across these variants. However, peripheral enablement (e.g., number of Ethernet channels or SDHI support) depends on flash size and silicon revision-always verify configuration registers and datasheet Table 1.2 before substitution.
