Overview
R5F564MLCDFP#31 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 4-MB code flash, 512-KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, CAN (3 channels), and 12-bit A/D (29 total channels). It targets industrial automation controllers requiring deterministic real-time I/O, secure connectivity, and functional safety support per IEC60730.
For engineers reviewing the R5F564MLCDFP#31 datasheet, R5F564MLCDFP#31 pinout, R5F564MLCDFP#31 application, or R5F564MLCDFP#31 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB + CAN coexistence, 120-MHz deterministic timing, on-chip ECC RAM, and hardware AES/SHA encryption for secure firmware updates and data integrity.
Technical Context
The R5F564MLCDFP#31 implements the RXv2 CPU core with 240 DMIPS performance at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its memory subsystem includes 4-MB zero-wait-state flash, 512-KB no-wait SRAM, 32-KB ECC-protected RAM, and 64-KB data flash rated for 100,000 erase/write cycles.
Peripherals are clocked across four domains: ICLK (up to 120 MHz for CPU), PCLKA (up to 120 MHz for ETHERC/USBA/AES), PCLKB (up to 60 MHz for timers/SCI/RIIC), and PCLKC/PCLKD (60 MHz for dual 12-bit A/D converters). The device supports IEEE 1588 PTP timestamping via EPTPC linked to ETHERC and offers hardware-accelerated cryptographic functions (AES-128/192/256, SHA-224/256, HMAC).
