Overview

Description

The RX66N Group microcontrollers feature flash memory that can be read with zero wait states from the CPU, delivering superior real-time performance. They are equipped with the third-generation RX CPU core, the RXv3 core, and these high-performance products operate at 120MHz. 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 RX66N can also contribute to the miniaturization of the housing and the shortening of the development cycle.

Features

  • 120MHz RXv3 core, double-precision FPU, and register bank save function that speeds up interrupt response
  • 4MB flash memory (120MHz read access, dual bank), 1MB SRAM
  • 182 general I/O ports
  • Ethernet, SD Host interface, USB 2.0 Full Speed, 3-channel CAN, QSPI
  • TFT LCD controller, 2D drawing engine, serial sound interface, CMOS camera interface
  • Encryption engines (AES, 3DES, RSA, ECC, SHA, TRNG), key management, flash memory protection
  • Single power supply with operation from 2.7V to 3.6V
  • Operating ambient temperature: -40 to 85°C or -40 to 105°C
