Overview
R5F571MGDDFC#30 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 IEEE 1588-compliant dual Ethernet MAC - designed for industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MGDDFC#30 datasheet, R5F571MGDDFC#30 pinout, R5F571MGDDFC#30 application, or R5F571MGDDFC#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel high-speed USB 2.0 with battery charging support, 3-channel CAN FD-capable interfaces, and hardware-accelerated AES/SHA encryption for IEC 60730 Class B compliance.
Technical Context
The R5F571MGDDFC#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP timing precision, supported by dedicated EPTPC and EDMAC peripherals for hardware timestamping and descriptor-based DMA offload.
Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL multiplication to generate independent clocks: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals - enabling precise domain isolation and low-jitter real-time operation.
