Product details
Overview
R5F571MLCDFB#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 - deployed in industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus coexistence.
For engineers reviewing the R5F571MLCDFB#30 datasheet, R5F571MLCDFB#30 pinout, R5F571MLCDFB#30 application, or R5F571MLCDFB#30 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual Ethernet channel isolation, 240-MHz real-time interrupt latency, and hardware AES/SHA acceleration for secure boot and OTA integrity verification.
Technical Context
The R5F571MLCDFB#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates two independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and EPTPC blocks compliant with IEEE 1588-2008 for hardware timestamping and PTP synchronization.
Its clock system supports simultaneous operation of ICLK at 240 MHz, PCLKA at 120 MHz (for Ethernet, USB, AES), and PCLKB at 60 MHz (for timers, ADC, serial interfaces), with independent frequency division/multiplication per domain and low-jitter PLL synthesis from external crystal or internal HOCO.
