Product details
Overview
R5F564MJCDFB#31 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging support, and integrated 12-bit A/D and D/A converters - deployed in industrial automation controllers requiring real-time deterministic I/O, secure firmware updates, and time-synchronized networked operation.
For engineers reviewing the R5F564MJCDFB#31 datasheet, R5F564MJCDFB#31 pinout, R5F564MJCDFB#31 application, or R5F564MJCDFB#31 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel Ethernet with PTP hardware timestamping, on-chip FPU for motion control math, 64 KB data flash rated for 100,000 erase/write cycles, and IEC60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnostic.
Technical Context
The R5F564MJCDFB#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs with dedicated EPTPC (IEEE 1588) and EDMAC controllers, supporting MII/RMII interfaces and cut-through frame forwarding between channels.
Its clock system combines external crystal input (8–24 MHz), internal HOCO/LOCO oscillators, and PLL-based frequency synthesis to deliver independent clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers and analog modules - enabling precise timing isolation across subsystems.

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 |
|---|---|---|---|
| R5F565NEDDFB#31 | Same RX65N Group, 176-pin LFBGA, but adds 2 MB SRAM, 8 MB flash, and enhanced security (TRNG, RSA accelerator); no USB battery charging. | Better suited for edge AI inference or larger RTOS deployments; lacks USBA PHY for direct battery-charging USB device support. | Select when higher memory bandwidth or cryptographic acceleration outweighs USB charging capability. |
| R7FA6M2AF3CFB#AA0 | RX72M Group successor: 240 MHz CPU, single Ethernet MAC, no IEEE 1588 hardware, added CAN FD, lower power consumption. | Targets cost-sensitive motion control where dual Ethernet and PTP are unnecessary; requires external PHY for USB. | Select for next-generation designs prioritizing higher CPU throughput and CAN FD over legacy PTP/Ethernet redundancy. |
Compared with R5F564MJCDFB#31, R5F565NEDDFB#31 offers greater memory headroom and advanced crypto but removes USB battery charging, while R7FA6M2AF3CFB#AA0 trades dual PTP Ethernet for higher clock speed and CAN FD - making R5F564MJCDFB#31 optimal for time-synchronized industrial gateways requiring integrated USB charging and dual-MAC redundancy.
