Product details
Overview
R5F571MJGGFC#V0 from Renesas is a 32-bit RXv2 core 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 R5F571MJGGFC#V0 datasheet, R5F571MJGGFC#V0 pinout, R5F571MJGGFC#V0 application, or R5F571MJGGFC#V0 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + high-speed USB 2.0 + CAN triple interface concurrency, 240-MHz deterministic real-time performance, and IEC60730 safety support including CRC, IWDTa, and A/D self-diagnostic functions.
Technical Context
The R5F571MJGGFC#V0 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload frame handling from the CPU.
Its clock system supports simultaneous domain-specific frequencies: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals - all derived from PLL, HOCO, or external crystal sources with independent division/multiplication settings.
