Product details
Overview
R5F571MJDDFB#30 from Renesas is a 32-bit RXv2 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 dual 12-bit A/D converters (8 + 21 channels). It serves as the main application processor in industrial Ethernet gateways requiring real-time control, secure communication, and deterministic timing.
For engineers reviewing the R5F571MJDDFB#30 datasheet, R5F571MJDDFB#30 pinout, R5F571MJDDFB#30 application, or R5F571MJDDFB#30 equivalent, key selection criteria include IEEE 1588-compliant Ethernet MAC support, high-speed USB 2.0 with battery charging, CAN v2.0B compliance, SD host interface capability, and IEC60730 safety features for functional safety certification.
Technical Context
The R5F571MJDDFB#30 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 processing from the CPU.
Its clock system supports multiple independent domains: 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. The device includes hardware-accelerated cryptographic engines (AES-128/192/256, DES/T-DES, SHA-1/224/256) and a memory protection unit (MPU) for secure partitioning of firmware and data spaces.
