Overview
R5F564MFCDFB#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 serves as a high-integration industrial control and networked edge node MCU in programmable logic controllers and gateway devices.
For engineers reviewing the R5F564MFCDFB#31 datasheet, R5F564MFCDFB#31 pinout, R5F564MFCDFB#31 application, or R5F564MFCDFB#31 equivalent, key selection criteria include its 176-pin LFBGA package, dual Ethernet + USB + CAN coexistence, 120 MHz real-time deterministic performance, and IEC60730 safety support for functional safety-critical firmware.
Technical Context
The R5F564MFCDFB#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its memory subsystem includes 4 MB on-chip code flash (no wait states at 120 MHz), 64 KB data flash (100,000 write cycles), and 512 KB SRAM - all operating without wait states.
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/USBb), and PCLKC/PCLKD (60 MHz for dual 12-bit A/D units). The device supports IEEE 1588 timestamping via EPTPC linked to ETHERC and provides hardware-accelerated AES/SHA/DES encryption.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F565NEDDFB#31 | Same RX65N Group pinout but adds 2 MB SRAM, 8 MB flash, and enhanced security (TRNG, secure boot ROM); lacks USB battery charging | Better suited for secure IoT edge nodes requiring larger code footprint and cryptographic root-of-trust | Select when >4 MB flash or hardware TRNG is mandatory; not drop-in due to different USB feature set |
| R5F566TEADFP#30 | RX66T Group part in 144-pin LQFP; 160 MHz CPU, 32 KB data flash, no Ethernet MAC, adds 3-phase PWM timer (GPTP) optimized for motor control | Targeted at cost-sensitive inverter drives where Ethernet is unnecessary but advanced PWM timing is critical | Choose for motor-specific timing features and lower package cost; requires PCB redesign due to LQFP vs LFBGA and missing Ethernet |
Compared with R5F564MFCDFB#31, R5F565NEDDFB#31 offers higher memory density and stronger security at the expense of USB battery charging, while R5F566TEADFP#30 trades Ethernet connectivity for motor-optimized PWM hardware in a smaller, lower-cost package - neither is pin-compatible, and both require layout and firmware adaptation.
