Overview

The R5F564MLCDFC#31 is a high-performance 32-bit microcontroller from the Renesas RX64M group, featuring a 120MHz RXv2 core with an integrated Floating Point Unit (FPU) and DSP instructions. It offers an expansive 4MB of flash memory and 512KB of SRAM, making it suitable for memory-intensive industrial applications that require real-time processing and extensive connectivity.

Why Choose This Part

This MCU provides a robust safety and reliability suite, including ECC memory and an Event Link Controller (ELC) that reduces CPU overhead by allowing peripherals to interact directly. Its massive 4MB flash allows for significant local data logging or complex middleware without requiring external memory chips.

Applications

Industrial Automation Control
High memory capacity and FPU performance enable complex PLC-like control logic and motor control algorithms.
Networked Gateways
Utilizes the large RAM and flash to handle communication stacks for bridging industrial Ethernet and fieldbus protocols.
Smart Energy Management
Integrated SEC-DED (Error Correction Code) on RAM and self-diagnostic ADC features support reliable monitoring in power distribution systems.
Human-Machine Interface (HMI)
The 176-pin package provides ample I/O for driving mid-sized graphical displays and peripheral expansion.

Getting Started

Develop using the Renesas e2 studio IDE or IAR Embedded Workbench for RX. Hardware evaluation is best performed using the Renesas Starter Kit+ for RX64M (RTK50564MSS00000BE) and the E1 or E2 On-Chip Debugging Emulators.
