For engineers reviewing the R5F564MLCGFC#V1 datasheet, R5F564MLCGFC#V1 pinout, R5F564MLCGFC#V1 application, or R5F564MLCGFC#V1 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), functional pin roles, IEC60730-ready safety features, and validated alternative MCUs for migration or second-sourcing - all grounded in Renesas R01DS0173EJ0120 Rev.1.20 documentation.

Technical Context

The R5F564MLCGFC#V1 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP timing, EPTPC hardware timestamping, and EDMAC with 3-channel DMA - optimized for deterministic networked control systems.

Its clock system combines external crystal (8–24 MHz) with internal PLL and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated), allowing independent domain clocking: ICLK up to 120 MHz, PCLKA up to 120 MHz for high-speed peripherals, and PCLKB up to 60 MHz for timers and ADCs - enabling precise power/performance trade-offs across low-power and real-time domains.
