Overview
Description
The RX72N Group microcontrollers are equipped with the third-generation RX CPU core, the RXv3 core, and these high-performance products operate at 240MHz. Real-time control and networking of equipment are realized with a single chip with 4MB flash memory capable of read operations at 120MHz, 1MB of SRAM and 182 general-purpose I/O ports. The device also supports high-end HMI functionality for advanced display capability. The device also has complete security capability, vital for industrial and consumer equipment today. The RX72N can also contribute to the miniaturization of the housing and the shortening of the development cycle.
