Overview

The R5F5651CDDFP#30 is a high-performance 32-bit microcontroller from the Renesas RX651 series, powered by the 120MHz RXv2 core. It features 1.5MB of Flash memory, 640KB of RAM, and 32KB of data EEPROM, making it suitable for complex control applications requiring significant memory overhead. This MCU provides extensive connectivity options including Ethernet, CANbus, and USB, along with dual-bank Flash functionality for secure background firmware updates.

Why Choose This Part

This MCU offers a high memory-to-pin-count ratio with 1.5MB Flash in a 100-LQFP package. The RXv2 core delivers high computational efficiency with an integrated FPU, while the dual-bank Flash enables robust over-the-air (OTA) updates with minimal downtime.

Applications

Industrial Network Gateways
Utilizes the integrated Ethernet and CANbus interfaces to bridge fieldbus protocols and industrial networks.
Human Machine Interface (HMI)
The 640KB RAM and high clock speed support driving small to medium graphic displays and touch interfaces.
Building Automation Controllers
Manages HVAC, lighting, and security systems using its diverse serial communication ports (UART, I2C, SPI).
IoT Edge Gateways
Provides enough processing power and memory to handle local data logging and secure TLS communication for cloud connectivity.
