Overview

The H8SX Family has a 32-bit CISC CPU with a maximum operating frequency of 50 MHz and abundant on-chip peripheral functions, realizing improved user system throughput. It inherits the instruction set of the H8S and enhances it, and it is upward compatible with the H8/H8S at the object level, so H8S software resources can be used effectively.

Family Lineup

H8SX Family

H8SX/1500

The H8SX/1500 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 48 MHz. The series is also equipped with peripheral functions very suitable for automotive controls, such as SSU* and CAN, which are LAN standard and employ a 5 V single power supply. It is a series well suited for industrial use, with the automotive field and factory automation as the focus. Models with large capacity flash memory and  improved peripheral functions are currently in development. *SSU:Synchronous Serial Communication Unit

H8SX/1600

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.
