For engineers reviewing the R5F564MLHDBG#21 datasheet, R5F564MLHDBG#21 pinout, R5F564MLHDBG#21 application, or R5F564MLHDBG#21 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC + PTP controller, USB 2.0 FS with battery charging support, 3-channel CAN, and hardware AES/SHA encryption for IEC 60730 Class B compliance.
Technical Context
The R5F564MLHDBG#21 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, CISC Harvard architecture, 5-stage pipeline, 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, ADC, and low-speed interfaces.
Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, 512 KB SRAM with no wait states, and 32 KB ECC-protected RAM supporting SEC-DED error correction - all coordinated via an on-chip memory protection unit (MPU) and trusted memory (TM) blocks 8–9 for secure boot partitioning.
