For engineers reviewing the R5F564MLHDFB#31 datasheet, R5F564MLHDFB#31 pinout, R5F564MLHDFB#31 application, or R5F564MLHDFB#31 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, IEC60730-ready safety features, and validated alternative MCUs for migration paths in industrial automation and edge control systems.
Technical Context
The R5F564MLHDFB#31 implements the RXv2 core with single-precision IEEE-754 FPU, 240 DMIPS performance, and memory protection unit (MPU) - enabling deterministic real-time execution in safety-critical contexts. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120-kHz clock for fail-safe monitoring.
