Overview
R5F564MLDDFC#31 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with single-precision FPU, 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, and CAN interface - designed for industrial networking, gateway control, and real-time edge processing in harsh environments.
For engineers reviewing the R5F564MLDDFC#31 datasheet, R5F564MLDDFC#31 pinout, R5F564MLDDFC#31 application, or R5F564MLDDFC#31 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB + CAN coexistence, 12-bit dual A/D with self-diagnostic, 32 KB ECC RAM, and IEC60730 safety support - all operating across –40°C to +105°C.
Technical Context
The R5F564MLDDFC#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, Harvard architecture, variable-length instructions, and MPU support. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP timing via EPTPC, plus dedicated EDMAC channels (3 total) for zero-copy frame handling and hardware timestamping.
Its clock system combines external crystal (8–24 MHz), internal HOCO/LOCO oscillators, and PLL for independent domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz (for ETHERC/USBA/AES), PCLKB up to 60 MHz (for timers/ADC), and BCLK up to 60 MHz for external bus interfacing - enabling deterministic real-time peripheral scheduling.
