Product details
Overview
R5F571MFDGFC#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and hardware AES/SHA encryption - deployed in industrial gateways requiring deterministic real-time networking and secure firmware updates.
For engineers reviewing the R5F571MFDGFC#V0 datasheet, R5F571MFDGFC#V0 pinout, R5F571MFDGFC#V0 application, or R5F571MFDGFC#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional pin roles, real-world use cases in time-sensitive networking, and two validated alternative MCUs with documented interface and memory trade-offs.
Technical Context
The R5F571MFDGFC#V0 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) - enabling deterministic real-time execution for IEC 60730 Class B safety-critical firmware. Its clock architecture supports independent domain scaling: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC, USBA, AES), and PCLKB up to 60 MHz (for timers, ADC, SCI).
It integrates dual Ethernet controllers with IEEE 1588 PTP hardware timestamping (EPTPCa), three CAN modules (32 mailboxes each), and a dedicated EXDMAC with cluster transfer mode - allowing concurrent high-bandwidth data movement between Ethernet, USB, and external SDRAM without CPU intervention. The device supports full-duplex audio via dual SSI interfaces with SRC and 24-bit stereo sampling.
