For engineers reviewing the R5F571MGGDBG#20 datasheet, R5F571MGGDBG#20 pinout, R5F571MGGDBG#20 application, or R5F571MGGDBG#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, real-world use cases for industrial automation and energy metering, and two validated alternative MCUs with documented interface and memory trade-offs.
Technical Context
The R5F571MGGDBG#20 implements the RXv2 CPU core with single-precision IEEE-754 FPU, 480 DMIPS performance at 240 MHz, and hardware-accelerated AES/SHA/DES encryption. It integrates dual Ethernet controllers (ETHERC + EPTPC) compliant with IEEE 1588-2008 for sub-microsecond time synchronization and supports full-duplex 100 Mbps operation via MII/RMII.
Its peripheral set includes three CAN modules (32 mailboxes each), four SCIFA interfaces with 16-byte FIFOs, two USB modules (FS-only USBb + HS-capable USBAa), and dual 12-bit S12ADC units (8 + 21 channels) with self-diagnostic and disconnection detection - all synchronized to independent clock domains (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
