For engineers reviewing the R5F564MLHDLK#21 datasheet, R5F564MLHDLK#21 pinout, R5F564MLHDLK#21 application, or R5F564MLHDLK#21 equivalent, this page delivers verified package mapping (176-pin LFBGA), confirmed peripheral counts (3× CAN, 2× Ethernet, 9× SCI), exact clock domain assignments (PCLKA up to 120 MHz, PCLKB up to 60 MHz), and validated alternative MCU options for migration or second sourcing.
Technical Context
The R5F564MLHDLK#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 240 DMIPS at 120 MHz. It integrates dual independent Ethernet controllers (ETHERC) with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC channels for zero-copy frame handling.
Its memory subsystem includes 4 MB of no-wait-state code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and 512 KB SRAM - 32 KB of which features SEC-DED ECC. Peripheral clock domains are strictly partitioned: PCLKA drives Ethernet/USB/AES at up to 120 MHz, while PCLKB governs timers, ADC, and I²C at up to 60 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F565NEHDFP#30 | Same RX65N family, 100-pin LQFP, 2 MB flash, no Ethernet MAC, adds TrustZone-based secure boot | Targeted at cost-sensitive edge nodes where Ethernet is replaced by Wi-Fi/BLE via external modules | Select when footprint reduction and hardware root-of-trust outweigh dual Ethernet requirement |
