Overview
R5F571MJHGFC#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip 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 real-time protocol bridging, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MJHGFC#V0 datasheet, R5F571MJHGFC#V0 pinout, R5F571MJHGFC#V0 application, or R5F571MJHGFC#V0 equivalent, this page delivers verified package mapping (176-pin LFBGA), confirmed peripheral channel counts (2× ETHERC, 3× CAN, 9× SCI), functional distinctions vs. alternatives, and design-meaningful specifications - all extracted from Renesas R01DS0249EJ0120 Rev.1.20.
Technical Context
The R5F571MJHGFC#V0 implements the RXv2 core with 480 DMIPS at 240 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. It integrates two independent Ethernet controllers (ETHERC) each with IEEE 1588 PTP support via EPTPC, and three CAN modules compliant with ISO 11898-1 - enabling time-synchronized multi-protocol industrial networking.
Its memory subsystem includes 4 MB code flash (no-wait up to 120 MHz), 64 KB data flash (100,000 write cycles), 512 KB SRAM (with 32 KB ECCRAM), and 8 KB standby RAM. Clock architecture supports simultaneous operation at ICLK = 240 MHz, PCLKA = 120 MHz (for ETHERC/USBA/AES), and PCLKB = 60 MHz (for timers/I/O).
