Product details
Overview
R5F571MLGDFC#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 - designed for industrial real-time control, networked gateway, and secure edge node applications.
For engineers reviewing the R5F571MLGDFC#30 datasheet, R5F571MLGDFC#30 pinout, R5F571MLGDFC#30 application, or R5F571MLGDFC#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional pin assignments, IEC60730-ready safety features, and validated alternative MCUs for migration or sourcing flexibility.
Technical Context
The R5F571MLGDFC#30 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 MACs with IEEE 1588 PTP hardware timestamping, high-speed USB 2.0 with battery charging (USBAa), and three CAN modules compliant with ISO 11898-1 - all synchronized across independent clock domains (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Its memory subsystem includes 4 MB code flash with background programming/erasing (BGO), 64 KB data flash rated for 100,000 write/erase cycles, and segmented SRAM with region-specific wait-state behavior: 256 KB accessible at full 240 MHz, while the upper 256 KB incurs one wait state above 120 MHz. The device supports IEC60730 Class B compliance via oscillation-stop detection, CRC engines, IWDTa with window function, and A/D self-diagnostic capability.
