For engineers reviewing the R5F564MFHDFB#31 datasheet, R5F564MFHDFB#31 pinout, R5F564MFHDFB#31 application, or R5F564MFHDFB#31 equivalent, key selection criteria include its 177-pin TFLGA package (8 × 8 mm), dual Ethernet + PTP support, 127 GPIOs with 5-V tolerance, 12-bit dual A/D converters (29 total channels), and IEC60730 safety features including self-diagnostic A/D and oscillation-stop detection.
Technical Context
The R5F564MFHDFB#31 implements the RXv2 CPU core with 240 DMIPS performance at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. It integrates a memory protection unit (MPU), JTAG/FINE debug interfaces, and supports little- or big-endian data arrangement.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for flexible domain partitioning: ICLK up to 120 MHz, PCLKA up to 120 MHz (for ETHERC, USBA, AES), PCLKB up to 60 MHz (for timers, SCI), and dedicated ADCLK domains for S12AD units.

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 |
|---|---|---|---|
| R5F565NEHDFB#31 | Same RX64M family, identical 177-pin TFLGA package, but with 2 MB flash, 384 KB SRAM, and no USBA module (lacks battery charging USB) | Suitable for cost-sensitive gateways where full USB battery charging is unnecessary and firmware footprint fits within 2 MB | Select when reducing BOM cost is critical and cryptographic acceleration (AES/SHA) remains required |
| R5F572MHDFB#31 | RX72M family successor: 240 MHz CPU, 4 MB flash, enhanced EtherCAT slave support, but larger 216-pin LFBGA (13 × 13 mm) and no SDHI | Better suited for high-performance motion control with integrated EtherCAT slave stack and higher PWM resolution | Choose for next-gen designs needing >200 MHz real-time throughput and EtherCAT conformance - not drop-in compatible due to package and pinout change |
Compared with R5F564MFHDFB#31, R5F565NEHDFB#31 reduces memory and removes USB battery charging while retaining PTP/Ethernet and crypto engines; R5F572MHDFB#31 delivers higher CPU performance and EtherCAT support but requires PCB redesign due to incompatible 216-pin LFBGA packaging and missing SDHI interface.
