Renesas' RX63N and RX631 32-bit microcontrollers are capable of operating at up to 100 MHz. The built-in flash is capable of accessing with no wait, and at 100 MHz high-performance processing of 165 DMIPS (Dhrystone MIPS) is realized. A broad memory lineup from 2 MB to 256 KB built-in flash (+ ROMless), to 256 KB to 64 KB built-in RAM is available to match the scale of your system. All products also contain 32 KB of built-in Flash memory for data storage. An abundant selection of packages is also available, from 48 to 177 pins.

Features

• Up to 21-channels of 12-bit A/D converter, and up to 2-channels of D/A converter
• High-function timer and pulse output functions which make PWM output for motor control possible
• Independent watchdog timer, and CRC function for supporting the home appliance safety standard (IEC 60730) for Europe
• Abundant communication functions, such as SCI, RSPI, and I²C

Special Functions

• Connectivity
  • The RX63N and the RX631 have built-in USB 2.0 full-speed (Function/Host/OTG) functionality, and CAN can be selected as an option. There are also RX631 products that have two built-in USB channels while still having a low pin count. The RX63N has an Ethernet controller which is suitable for networking equipment. Since the RX631 and the RX63N have 192 KB/256 KB large-capacity on-chip RAM, which can be used for buffering a variety of communication functions, they are also suitable for gateway devices such as HEMS and BEMS and industrial networking equipment
• Sensing by CMOS camera, and image display
  • The RX631 has a built-in parallel data capture unit (PDC) that can connect to a CMOS camera module. The PDC can capture images from the CMOS camera for simple image sensor applications such as a motion detector or barcode reader. Furthermore, by using the built-in USB or ExDMAC of the RX631, the entire process from image capture to display can be performed using a single chip 
• Security
  • The RX63N and the RX631 have a built-in data encryption unit (DEU) that processes AES encryption/decryption by hardware without putting a load on the CPU, making them suitable for devices that handle private information or require security
