Overview
R5F564MGHDFP#31 from Renesas is a 120-MHz 32-bit RXv2 core MCU with single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), and integrated IEEE 1588-compliant Ethernet MAC - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and time-synchronized networked I/O.
For engineers reviewing the R5F564MGHDFP#31 datasheet, R5F564MGHDFP#31 pinout, R5F564MGHDFP#31 application, or R5F564MGHDFP#31 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed peripheral channel counts for 176-pin variants, and two validated alternative MCUs with documented functional trade-offs.
Technical Context
The R5F564MGHDFP#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates dual A/D converters (8 + 21 channels), two 12-bit D/A channels, and hardware AES/SHA encryption supporting 128–256-bit keys.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and dedicated IWDT oscillator. Peripheral clocks are independently configurable: PCLKA up to 120 MHz (for ETHERC, USBA, AES), PCLKB up to 60 MHz (for TMR, CMT, RTC), and ADCLK up to 60 MHz per A/D unit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F565NEHDFP#31 | Same RX65N Group, 120 MHz, but adds TrustZone-based secure boot and 2 MB extra code flash; lacks USBA module with battery charging. | Better suited for secure boot-critical applications (e.g., medical devices), but cannot replace R5F564MGHDFP#31 where USB BC1.2 charging is required. | Select when hardware root-of-trust and secure firmware validation are mandatory; avoid if USB battery charging detection is needed. |
| R7FA6M2AF3CFP#AA0 | RX72M Group part: 240 MHz CPU, same 4 MB flash/SRAM, adds CAN FD and enhanced PTP (sub-100 ns sync), but removes SDHI and QSPI. | Optimized for ultra-low-jitter motion control and robotics; incompatible with designs relying on SD card logging or quad-SPI flash expansion. | Choose for next-gen industrial drives needing CAN FD and tighter time sync; not drop-in for SDHI/QSPI-dependent systems. |
Compared with R5F564MGHDFP#31, R5F565NEHDFP#31 prioritizes security over USB charging capability, while R7FA6M2AF3CFP#AA0 trades SD/QSPI flexibility for higher CPU performance and CAN FD - both require PCB layout changes and firmware adaptation.
