Product details
Overview
R5F571MGDGFB#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring on-chip FPU, 4 MB code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN, and 12-bit A/D converters - deployed in industrial gateways requiring real-time networking, secure firmware updates, and deterministic I/O control.
For engineers reviewing the R5F571MGDGFB#V0 datasheet, R5F571MGDGFB#V0 pinout, R5F571MGDGFB#V0 application, or R5F571MGDGFB#V0 equivalent, key selection criteria include dual Ethernet + PTP timing accuracy, 177-pin TFLGA package compatibility, 240-MHz deterministic execution, hardware AES/SHA encryption, and support for IEC60730 functional safety diagnostics.
Technical Context
The R5F571MGDGFB#V0 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, single-cycle 32×32 multiplier, and IEEE-754-compliant FPU - enabling real-time signal processing in motor control and audio applications. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, with independent domain clocks (ICLK ≤ 240 MHz, PCLKA ≤ 120 MHz, PCLKB ≤ 60 MHz).
It supports IEC60730 compliance via oscillation-stop detection, CRC engine, self-diagnostic A/D, register write protection, and independent watchdog timer (IWDTa) with configurable windowing - all validated for Class B safety-critical embedded systems. The ELC (Event Link Controller) enables CPU-free peripheral coordination across 119 internal event signals.
