Product details
Overview
R5F571MLGDFB#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MLGDFB#V0 datasheet, R5F571MLGDFB#V0 pinout, R5F571MLGDFB#V0 application, or R5F571MLGDFB#V0 equivalent, key selection criteria include dual Ethernet timing precision (IEEE 1588 PTP), 240-MHz deterministic interrupt latency, 4-MB flash for field-upgradable firmware, hardware AES/SHA crypto acceleration, and 177-pin TFLGA package compatibility with industrial PCB thermal and EMI constraints.
Technical Context
The R5F571MLGDFB#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and single-cycle 32×32 multiplier - enabling 480 DMIPS at 240 MHz while supporting IEEE-754 single-precision floating-point and DSP instructions. Its memory subsystem integrates 4 MB code flash (with AFU-assisted zero-wait access up to 120 MHz), 64 KB data flash (100k write cycles), and 512 KB SRAM split across no-wait and wait-state regions based on ICLK frequency.
Peripherals are clocked via independent domain dividers: PCLKA (up to 120 MHz) drives Ethernet, USB, AES, and RSPI; PCLKB (up to 60 MHz) serves timers, ADC, and I/O; PCLKC/D (60 MHz) feed dual 12-bit S12ADC units. The device supports IEEE 1588 timestamping via EPTPC linked to ETHERC, and real-time determinism is reinforced by ELC event linking, 298-interrupt-source ICUA, and four low-power modes including deep software standby with 8 KB backup RAM.
