Product details
Overview
R5F571MFHDFP#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and dual 12-bit A/D converters - deployed in industrial gateways requiring real-time protocol handling, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MFHDFP#30 datasheet, R5F571MFHDFP#30 pinout, R5F571MFHDFP#30 application, or R5F571MFHDFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), confirmed peripheral channel counts for Ethernet/USB/CAN, and validated alternative MCUs for migration paths in IEC 60730-certifiable systems.
Technical Context
The R5F571MFHDFP#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point math for motor control and signal processing. It integrates dual Ethernet controllers (ETHERC) with EPTPC for IEEE 1588 timestamping and EDMAC for descriptor-based DMA offload.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL for ICLK up to 240 MHz, while PCLKA (≤120 MHz) drives Ethernet, USB, and AES, and PCLKB (≤60 MHz) clocks ADC, timers, and serial interfaces - ensuring precise domain isolation for real-time subsystems.
