Product details
Overview
R5F571MFDGFP#V0 from Renesas is a 32-bit RXv2 microcontroller designed for industrial Ethernet and real-time control applications. It operates at up to 240 MHz, delivers 480 DMIPS, integrates IEEE 1588-compliant Ethernet MAC, dual CAN interfaces, and 4 MB on-chip code flash memory. Its role includes deterministic real-time processing in networked PLCs and motor drives requiring precise timing and secure firmware execution.
For engineers reviewing the R5F571MFDGFP#V0 datasheet, R5F571MFDGFP#V0 pinout, R5F571MFDGFP#V0 application, or R5F571MFDGFP#V0 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual-CAN mailbox count (32 per channel), 240-MHz real-time interrupt latency, and support for IEC 60730 Class B safety diagnostics including CRC, oscillation-stop detection, and A/D self-test.
Technical Context
The R5F571MFDGFP#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports little-endian data and configurable instruction endianness, with single-cycle 32×32-bit multiply and two-cycle 32/32-bit divide operations.
Its clock system combines external crystal (8–24 MHz) with internal PLL and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated), allowing independent domain clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz for Ethernet/AES/USB, and PCLKB up to 60 MHz for timers and serial interfaces - enabling concurrent high-speed peripheral operation without CPU contention.
