Product details
Overview
R5F571MGGGFB#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, single-precision FPU, 4 Mbyte on-chip code flash, 512 Kbyte SRAM (including 32 Kbyte ECCRAM), and IEEE 1588-compliant dual Ethernet MAC - designed for industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus integration.
For engineers reviewing the R5F571MGGGFB#V0 datasheet, R5F571MGGGFB#V0 pinout, R5F571MGGGFB#V0 application, or R5F571MGGGFB#V0 equivalent, key selection criteria include 176-pin LFBGA package compatibility, -40°C to +105°C extended temperature operation, dual CAN v2.0B support, hardware AES/SHA crypto acceleration, and integrated SDHI/MMCIF for local firmware storage and field data logging.
Technical Context
The R5F571MGGGFB#V0 implements the RXv2 core with 5-stage CISC Harvard pipeline, 480 DMIPS at 240 MHz, and IEEE-754-compliant FPU - enabling high-precision motor control and sensor fusion without external coprocessors. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent PCLKA/PCLKB domains to drive Ethernet (PCLKA ≤120 MHz) and peripherals like ADC (PCLKD ≤60 MHz) concurrently.
Real-time determinism is enforced via ELC (Event Link Controller) linking 119 internal signals - allowing timer-triggered A/D conversion, PWM dead-time compensation, and RTC time-capture without CPU intervention. Memory subsystem includes 4 Mbyte code flash with background programming, 64 Kbyte data flash (100k erase cycles), and 8 Kbyte standby RAM backed by VBATT for RTC retention during deep software standby.
