Product details
Overview
R5F571MLCGFB#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS and integrated single-precision IEEE-754 FPU. It integrates 4 MB code flash, 512 KB SRAM (including 32 KB ECC RAM), dual 12-bit ADCs (29 total channels), IEEE 1588-compliant Ethernet MAC, and high-speed USB 2.0 with battery charging - designed for industrial real-time control and networked edge devices.
For engineers reviewing the R5F571MLCGFB#V0 datasheet, R5F571MLCGFB#V0 pinout, R5F571MLCGFB#V0 application, or R5F571MLCGFB#V0 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 240-MHz deterministic real-time performance, dual Ethernet + USB HS + CAN triple connectivity, IEC60730 safety features, and support for SD host, QSPI, and parallel camera interface in a single-chip solution.
Technical Context
The R5F571MLCGFB#V0 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for secure embedded execution. Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet/USB/AES), and PCLKB up to 60 MHz (for timers/ADC).
It supports four low-power modes (sleep, all-module clock stop, software standby, deep software standby) with RTC backup via VBATT and ultra-low active power of 0.2 mA/MHz (typ.). Safety-critical operation is reinforced by oscillation-stop detection, CRC engines, IWDTa with window function, register write protection, and A/D self-diagnostic functions compliant with IEC60730 Class B.
