1.1
Features
The core of each product in the H8SX/1650 Group of CISC (complex instruction set computer)
microcomputers is an H8SX CPU, which has an internal 32-bit architecture. The H8SX CPU
provides upward-compatibility with the CPUs of other Renesas Technology-original
microcomputers; H8/300, H8/300H, and H8S.
As peripheral functions, each LSI of the Group includes a bus-state controller that enables direct
connection to different kinds of memory. The LSI of the Group also includes serial
communication interfaces, A/D and D/A converters, and a multi-function timer that makes motor
control easy. Together, the modules realize low-cost configurations for end systems. The power
consumption of these modules are kept down dynamically by an on-chip power-management
function.
1.1.1
Applications
Examples of the applications of this LSI include PC peripheral equipment, optical storage devices,
office automation equipment, and industrial equipment.
Notes: The following additions and changes have been made in the switch from the H8SX/1650A
to the H8SX/1650C.
• The chip select signal is added to PF7, PF6, and PF5.
