Product details
Overview
R5F564MFCDFC#31 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with on-chip FPU, 240 DMIPS performance, 4-MB code flash, 512-KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, and CAN interface - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F564MFCDFC#31 datasheet, R5F564MFCDFC#31 pinout, R5F564MFCDFC#31 application, or R5F564MFCDFC#31 equivalent, key selection considerations include its 176-pin LFBGA (PLQP0176KB-A) package, dual-channel Ethernet with PTP hardware timestamping, integrated AES/SHA crypto engine, and support for IEC60730 Class B functional safety compliance.
Technical Context
The R5F564MFCDFC#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs with dedicated EPTPC hardware compliant with IEEE 1588-2008 for sub-microsecond time synchronization, plus an EDMAC with 3 channels (2 for ETHERC, 1 for EPTPC) to offload frame processing.
Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU execution, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers and ADCs. The device includes two 12-bit A/D converters (8 + 21 channels), dual 12-bit D/A outputs, and a temperature sensor with ±1°C relative precision - all synchronized via Event Link Controller (ELC) for deterministic trigger chaining without CPU intervention.
