Product details
Overview
R5F571MFHDLJ#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 R5F571MFHDLJ#20 datasheet, R5F571MFHDLJ#20 pinout, R5F571MFHDLJ#20 application, or R5F571MFHDLJ#20 equivalent, this MCU supports simultaneous high-speed USB 2.0 HS + battery charging, CAN FD-ready triple CAN interfaces, SD host interface, quad SPI, and hardware AES/SHA encryption - critical for IEC 60730 Class B safety certification and time-sensitive networking (TSN) edge node design.
Technical Context
The R5F571MFHDLJ#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 hardware (EPTPCa) compliant with IEEE 1588-2008 for sub-microsecond timestamping and synchronization across distributed nodes.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis - enabling independent domain clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC, USBA, AES), and PCLKB up to 60 MHz (for timers, ADC, SCI). The device includes ELC (Event Link Controller) for hardware-triggered peripheral chaining without CPU intervention.
