Product details
Overview
R5F571MFDDFC#30 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 (including 32 KB ECC RAM), 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 real-time deterministic I/O, secure firmware updates, and time-synchronized networked operation.
For engineers reviewing the R5F571MFDDFC#30 datasheet, R5F571MFDDFC#30 pinout, R5F571MFDDFC#30 application, or R5F571MFDDFC#30 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP support, 240-MHz real-time performance, and integrated AES/SHA crypto acceleration for IEC 60730 Class B compliance in safety-critical embedded systems.
Technical Context
The R5F571MFDDFC#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point execution at 240 MHz. Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and 512 KB SRAM split across no-wait and wait-state regions based on clock domain (ICLK ≤120 MHz vs. >120 MHz).
Peripheral integration centers on deterministic real-time control: dual ETHERC modules with EPTPC for IEEE 1588 timestamping, USBAa for high-speed USB 2.0 host/function with battery charging, and three independent CAN controllers each supporting 32 mailboxes. Clock domains are strictly segmented - ICLK (240 MHz), PCLKA (120 MHz for Ethernet/USB/AES), PCLKB (60 MHz for timers/SCI), and dedicated ADCLKs (60 MHz) - ensuring predictable timing isolation across mixed-criticality functions.
