Overview

Description

The RX621 microcontrollers have 100MHz high-speed operation and enhanced communications functions. They have built-in CAN and two circuits of USB 2.0 host controller. A multi-function timer (MTU2, 2 units), 10-bit or 12-bit A/D converter, DMA controller, and other peripheral functions are incorporated on a single chip. Up to 512KB of Flash memory and 96KB of RAM are built in, as well as 32KB of Flash memory for data storage. Packages are available from 85 pins to 176 pins.
