Product details
Overview
R5F571MFCGFB#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 (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and 12-bit A/D converters (29 total channels). It targets industrial networking gateways requiring deterministic real-time control, secure connectivity, and multi-protocol I/O.
For engineers reviewing the R5F571MFCGFB#V0 datasheet, R5F571MFCGFB#V0 pinout, R5F571MFCGFB#V0 application, or R5F571MFCGFB#V0 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS + CAN coexistence, 240-MHz real-time performance with FPU, IEC60730 safety features, and support for SD host interface and quad SPI in a single chip.
Technical Context
The R5F571MFCGFB#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point math for motor control and signal processing. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent peripheral clocks (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz) to decouple timing-critical peripherals like Ethernet and USB from CPU frequency scaling.
It supports full IEC60730 Class B compliance via hardware-assisted self-test: oscillation-stop detection, CRC engine, IWDTa with window function, register write protection, and A/D converter self-diagnostic. The ELC (Event Link Controller) enables zero-CPU-intervention peripheral coordination - e.g., triggering A/D conversion from TPU PWM edges or synchronizing RTC time capture with external event signals.
