For engineers reviewing the R5F564MLCDFB#31 datasheet, R5F564MLCDFB#31 pinout, R5F564MLCDFB#31 application, or R5F564MLCDFB#31 equivalent, this MCU supports IEC 60730 safety compliance, hardware AES/SHA encryption, dual 12-bit ADCs (29 total channels), full-speed USB 2.0 with battery charging, and SD host interface - critical for BOM-stable design of networked edge controllers.
Technical Context
The R5F564MLCDFB#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual clock domains: ICLK up to 120 MHz for CPU and high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers, ADCs, and communication interfaces.
Its memory subsystem includes 4 MB code flash (120 MHz, zero-wait), 64 KB data flash (100,000 write cycles), 512 KB SRAM (no wait), 32 KB ECC RAM (SEC-DED), and 8 KB standby RAM. Peripheral integration features two IEEE 1588-capable Ethernet MACs, three CAN modules (32 mailboxes each), nine SCIs, four SCIFAs, two RIICs, QSPI, SDHI, and parallel camera capture (PDC) - all mapped to 127 GPIOs with 5-V tolerance on 19 pins.
