Product details
Overview
R5F571MLCGFC#H0 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 dual 12-bit A/D converters (29 total channels). It targets industrial automation controllers requiring deterministic real-time I/O, secure firmware updates, and networked time synchronization.
For engineers reviewing the R5F571MLCGFC#H0 datasheet, R5F571MLCGFC#H0 pinout, R5F571MLCGFC#H0 application, or R5F571MLCGFC#H0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP support, 240-MHz real-time performance with FPU, and IEC60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnosis.
Technical Context
The R5F571MLCGFC#H0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a single-precision IEEE-754 FPU, two MAC units, and a 32-bit multiplier with one-cycle execution - all operating at 240 MHz system clock (ICLK) while peripheral modules run on independent clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Its communication subsystem includes dual IEEE 1588-compliant Ethernet MACs with dedicated EDMAC (3-channel), USBAa (HS USB 2.0 + BC1.2), USBb (FS/LS), three CAN modules (32 mailboxes each), nine SCIg/h interfaces with LIN/Smart Card modes, and QSPI for serial flash. Safety-critical functions are supported by IWDTa with windowing, MPU, ECCRAM (32 KB), and hardware-accelerated AES/SHA/DES encryption.
