Product details
Overview
R5F564MFCDLJ#21 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with single-precision FPU, 240 DMIPS performance, 4 MB on-chip code flash, 512 KB SRAM, and integrated IEEE 1588-compliant Ethernet MAC - designed for industrial real-time control, networked HMI, and secure edge node applications requiring deterministic timing and dual CAN/USB/Ethernet connectivity.
For engineers reviewing the R5F564MFCDLJ#21 datasheet, R5F564MFCDLJ#21 pinout, R5F564MFCDLJ#21 application, or R5F564MFCDLJ#21 equivalent, this MCU delivers verified real-time interrupt latency (fast interrupt), hardware-accelerated cryptography (AES-128/192/256, SHA-256), ECC-protected RAM, and IEC60730 safety support - critical for functional safety–certifiable designs in factory automation and energy infrastructure.
Technical Context
The R5F564MFCDLJ#21 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling ultra-compact code and secure memory partitioning. It executes floating-point operations per IEEE-754 single-precision standard and supports two multiply-and-accumulate units for DSP-intensive tasks.
Its clock system integrates PLL, LOCO/HOCO oscillators, and independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz), allowing precise domain isolation for Ethernet (PCLKA-synchronized EDMAC), ADC (PCLKC/D), and real-time timers. The device includes dedicated IWDTa running on 120-kHz LOCO-derived clock and RTC with battery backup via VBATT.

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 |
|---|---|---|---|
| R5F565NEHDFP#30 | Same RX65N group, 120 MHz, but 2 MB flash, no Ethernet MAC, adds TrustZone-based security extension. | Better suited for security-first applications (e.g., secure boot + OTA) where Ethernet is handled externally or omitted. | Select when cryptographic isolation (TrustZone) outweighs integrated Ethernet and larger flash capacity. |
| STM32H743ZIT6 | ARM Cortex-M7, 480 MHz, 2 MB flash, dual-core option, no native IEEE 1588 - requires external PHY and software PTP stack. | Higher raw compute throughput but lacks hardware-accelerated time synchronization and IEC60730 safety features out-of-box. | Select when maximum integer performance is prioritized and Ethernet timing precision is relaxed to >1 µs. |
Compared with R5F564MFCDLJ#21, the R5F565NEHDFP#30 trades integrated Ethernet and flash size for enhanced security isolation, while the STM32H743ZIT6 offers higher clock speed but demands additional firmware effort for PTP and safety certification - making R5F564MFCDLJ#21 optimal for time-critical, safety-aware industrial networking.
