Overview

The H8SX/1600 series has the Renesas exclusive high-speed, high-performance 32-bit CISC H8SX CPU core. Renesas has maintained object level compatibility with its existing H8 and H8S products while increasing the maximum operating frequency to 50 MHz. Also, features include easy connection to equipment by on-chip peripheral functions and large-capacity on-chip flash memory to support the increasing program sizes of enhanced systems. This series is well-suited for system control applications in both office equipment and consumer appliances. In order to support the increasing range of future applications, we will continue to develop improved on-chip peripheral functions and product with a  variety of on-chip memory units.
