Renesas R5F564MFCGFB#V1

Overview

R5F564MFCGFB#V1 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM, and integrated IEEE 1588-compliant Ethernet MAC, USB 2.0 FS with battery charging, CAN, SD host interface, and hardware encryption (AES/DES/SHA). It targets industrial automation controllers requiring real-time deterministic execution, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MFCGFB#V1 datasheet, R5F564MFCGFB#V1 pinout, R5F564MFCGFB#V1 application, or R5F564MFCGFB#V1 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet MAC support, 12-bit dual A/D converters with self-diagnostic capability, 32 KB ECC-protected RAM, and IEC60730 safety features for Class B compliance.

Technical Context

The R5F564MFCGFB#V1 implements the RXv2 CPU core with 5-stage CISC Harvard pipeline, 240 DMIPS performance at 120 MHz, and variable-length instructions enabling ultra-compact code density. It integrates dual independent clock domains: ICLK up to 120 MHz for CPU and high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers, ADCs, and low-speed interfaces.

Its peripheral architecture includes three dedicated DMA controllers-DMACAa (8 channels), EXDMACa (2 channels), and EDMACa (3 channels for Ethernet)-enabling concurrent high-bandwidth transfers without CPU intervention. The ELC (Event Link Controller) supports 119 internal event signals for hardware-triggered timer starts, A/D conversions, and PWM dead-time compensation, eliminating software latency in time-critical control loops.
