Overview
R5F571MLGDLC#20 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 - deployed in industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus coexistence.
For engineers reviewing the R5F571MLGDLC#20 datasheet, R5F571MLGDLC#20 pinout, R5F571MLGDLC#20 application, or R5F571MLGDLC#20 equivalent, this MCU supports IEC 60730 Class B compliance via hardware CRC, oscillation-stop detection, self-diagnostic A/D, register write protection, and independent watchdog timer - critical for functional safety validation in motor control and energy metering systems.
Technical Context
The R5F571MLGDLC#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with dedicated PTP timing engines (EPTPC) and three-channel EDMAC for zero-copy frame processing - supporting time-synchronized packet timestamping at sub-microsecond resolution.
Its memory subsystem includes 4 MB code flash with background programming/erasing (BGO), 64 KB data flash rated for 100,000 erase/write cycles, and segmented SRAM with differentiated wait-state behavior: 256 KB accessible at full 240 MHz ICLK, while upper 256 KB incurs one wait state above 120 MHz - enabling deterministic real-time task scheduling across mixed-criticality workloads.
