Overview
R5F564MGCDFC#31 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 4 MB code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging support, CAN (ISO 11898-1), and hardware AES/SHA encryption - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F564MGCDFC#31 datasheet, R5F564MGCDFC#31 pinout, R5F564MGCDFC#31 application, or R5F564MGCDFC#31 equivalent, this MCU delivers verified 240 DMIPS performance, on-chip ECC-protected RAM, BGO-capable data flash (100k write cycles), and IEC 60730-compliant safety features including oscillation-stop detection, CRC, and A/D self-diagnosis - critical for functional safety certification in motor drives and PLCs.
Technical Context
The R5F564MGCDFC#31 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, single-cycle 32×32 multiplier, and IEEE-754-compliant single-precision FPU - enabling high-efficiency floating-point math for motion control algorithms. Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU/core logic, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/ADC.
Real-time determinism is enforced via ELC (Event Link Controller) for zero-CPU-intervention peripheral interoperation, DTC/DMAC/EXDMAC for autonomous data movement, and MTU3/GPT with dead-time-compensated complementary PWM - all synchronized to precise PCLK domains. The device integrates dual Ethernet controllers with dedicated EDMAC (3-channel) and EPTPC for IEEE 1588 timestamping, plus USBA with 8.5 KB on-chip buffer and battery-charging capability.
