For engineers reviewing the R5F571MFHDLK#20 datasheet, R5F571MFHDLK#20 pinout, R5F571MFHDLK#20 application, or R5F571MFHDLK#20 equivalent, this page delivers verified package mapping (PLQP0176KB-A, 176-pin LFBGA), confirmed peripheral channel counts (2× ETHERC, 3× CAN, 9× SCI), IEEE 1588 PTP timestamping capability, and functional alternatives for industrial automation MCU selection.
Technical Context
The R5F571MFHDLK#20 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and single-cycle 32×32 multiplier - enabling 480 DMIPS at 240 MHz. It integrates dual Ethernet controllers with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC with 3 DMA channels per ETHERC.
